Without the existence of time travel, Harry must act fast to save the day.

Chapter 16

Harry's euphoria at finally winning the Quidditch Cup lasted at least a week. Even the weather seemed to be celebrating; as June approached, the days became cloudless and sultry, and all anybody felt like doing was strolling onto the grounds and flopping down on the grass with several pints of iced pumpkin juice, perhaps playing a casual game of Gobstones or watching the giant squid propel itself dreamily across the surface of the lake.

But they couldn't. Exams were nearly upon them, and instead of lazing around outside, the students were forced to remain inside the castle, trying to bully their brains into concentrating while enticing wafts of summer air drifted in through the windows. Even Fred and George Weasley had been spotted working; they were about to take their O.W.L.s (Ordinary Wizarding Levels). Percy was getting ready to take his N.E.W.T.s (Nastily Exhausting Wizarding Tests), the highest qualification Hogwarts offered. As Percy hoped to enter the Ministry of Magic, he needed top grades. He was becoming increasingly edgy, and gave very severe punishments to anybody who disturbed the quiet of the common room in the evenings. Harry, Ron, and Hermione had plenty of opportunity to speak to Hagrid.

"Beaky's gettin' a bit depressed," Hagrid told them, bending low on the pretense of checking that Harry's flobberworm was still alive. "Bin cooped up too long. But still...we'll know day after tomorrow - one way or the other -"

They had Potions that afternoon, which was an unqualified disaster. Try as Harry might, he couldn't get his Confusing Concoction to thicken, and Snape, standing watch with an air of vindictive pleasure, scribbled something that looked suspiciously like a zero onto his notes before moving away.

Then came Astronomy at midnight, up on the tallest tower; History of Magic on Wednesday morning, in which Harry scribbled everything Florean Fortescue had ever told him about medieval witch-hunts, while wishing he could have had one of Fortescue's choco-nut sundaes with him in the stifling classroom. Wednesday afternoon meant Herbology, in the greenhouses under a baking-hot sun; then back to the common room once more, with sunburnt necks, thinking longingly of this time next day, when it would all be over.

Their second to last exam, on Thursday morning, was Defense Against the Dark Arts. Professor Lupin had compiled the most unusual exam any of them had ever taken; a sort of obstacle course outside in the sun, where they had to wade across a deep paddling pool containing a Grindylow, cross a series of potholes full of Red Caps, squish their way across a patch of marsh while ignoring misleading directions from a Hinkypunk, then climb into an old trunk and battle with a new Boggart.

"Excellent, Harry," Lupin muttered as Harry climbed out of the trunk, grinning. "Full marks."

Flushed with his success, Harry hung around to watch Ron and Hermione. Ron did very well until he reached the Hinkypunk, which successfully confused him into sinking waist-high into the quagmire. Hermione did everything perfectly until she reached the trunk with the Boggart in it. After about a minute inside it, she burst out again, screaming.

"Hermione!" said Lupin, startled. "What's the matter?"

"P-P-Professor McGonagall!" Hermione gasped, pointing into the trunk. "Sh-she said I'd failed everything!"

It took a little while to calm Hermione down. When at last she had regained a grip on herself, she, Harry, and Ron went back to the castle. Ron was still slightly inclined to laugh at Hermione's Boggart, but an argument was averted by the sight that met them on the top of the steps.

Cornelius Fudge, sweating slightly in his pinstriped cloak, was standing there staring out at the grounds. He started at the sight of Harry.

"Hello there, Harry!" he said. "Just had an exam, I expect? Nearly finished?"

"Yes," said Harry. Hermione and Ron, not being on speaking terms with the Minister of Magic, hovered awkwardly in the background.

"Lovely day," said Fudge, casting an eye over the lake.

"Pity...pity..."

He sighed deeply and looked down at Harry.

"I'm here on an unpleasant mission, Harry. The Committee for the Disposal of Dangerous Creatures required a witness to the execution of a mad Hippogriff. As I needed to visit Hogwarts to check on the Black situation, I was asked to step in."

"Does that mean the appeal's already happened?" Ron interrupted, stepping forward.

"No, no, it's scheduled for this afternoon," said Fudge, looking curiously at Ron.

"Then you might not have to witness an execution at all!" said Ron stoutly. "The Hippogriff might get off!"

Before Fudge could answer, two wizards came through the castle doors behind him. One was so ancient he appeared to be withering before their very eyes; the other was tall and strapping, with a thin back mustache. Harry gathered that they were representatives of the Committee for the Disposal of Dangerous Creatures, because the very old wizard squinted toward Hagrid's cabin and said in a feeble voice, "Dear, dear, I'm getting too old for this...Two o'clock, isn't it, Fudge?"

The black-mustached man was fingering something in his belt; Harry looked and saw that he was running one broad thumb along the blade of a shining axe. Ron opened his mouth to say something, but Hermione nudged him hard in the ribs and jerked her head toward the entrance hall.

"Why'd you stop me?" said Ron angrily as they entered the Great Hall for lunch. "Did you see them? They've even got the axe ready! This isn't justice!"

"Ron, your dad works for the Ministry, you can't go saying things like that to his boss!" said Hermione, but she too looked very upset. "As long as Hagrid keeps his head this time, and argues his case properly, they can't possibly execute Buckbeak..."

But Harry could tell Hermione didn't really believe what she was saying. All around them, people were talking excitedly as they ate their lunch, happily anticipating the end of the exams that afternoon, but Harry, Ron, and Hermione, lost in worry about Hagrid and Buckbeak, didn't join in.

Harry's and Ron's last exam was Divination; Hermione's, Muggle Studies. They walked up the marble staircase together; Hermione left them on the first floor and Harry and Ron proceeded all the way up to the seventh, where many of their class were sitting on the spiral staircase to Professor Trelawney's classroom, trying to cram in a bit of last-minute studying.

"She's seeing us all separately," Neville informed them as they went to sit down next to him. He had his copy of Unfogging the Future open on his lap at the pages devoted to crystal gazing. "Have either of you ever seen anything in a crystal ball?" he asked them unhappily.

"Nope," said Ron in an offhand voice. He kept checking his watch; Harry knew that he was counting down the time until Buckbeak's appeal started.

The line of people outside the classroom shortened very slowly. As each person climbed back down the silver ladder, the rest of the class hissed, "What did she ask? Was it okay?"

But they all refused to say.

"She says the crystal ball's told her that if I tell you, I'll have a horrible accident!" squeaked Neville as he clambered back down the ladder toward Harry and Ron, who had now reached the landing.

"That's convenient," snorted Ron. "You know, I'm starting to think Hermione was right about her" - he jabbed his thumb toward the trapdoor overhead - "she's a right old fraud."

"Yeah," said Harry, looking at his own watch. It was now two o'clock. "Wish she'd hurry up..."

Parvati came back down the ladder glowing with pride.

"She says I've got all the makings of a true Seer," she informed Harry and Ron. "I saw loads of stuff...Well, good luck!"

She hurried off down the spiral staircase toward Lavender.

"Ronald Weasley," said the familiar, misty voice from over their heads. Ron grimaced at Harry and climbed the silver ladder out of sight. Harry was now the only person left to be tested. He settled himself on the floor with his back against the wall, listening to a fly buzzing in the sunny window, his mind across the grounds with Hagrid.

Finally, after about twenty minutes, Ron's large feet reappeared on the ladder.

"How'd it go?" Harry asked him, standing up.

"Rubbish," said Ron. "Couldn't see a thing, so I made some stuff up. Don't think she was convinced, though..."

"Meet you in the common room," Harry muttered as Professor Trelawney's voice called, "Harry Potter!"

The tower room was hotter than ever before; the curtains were closed, the fire was alight, and the usual sickly scent made Harry cough as he stumbled through the clutter of chairs and table to where Professor Trelawney sat waiting for him before a large crystal ball.

"Good day, my dear," she said softly. "If you would kindly gaze into the Orb...Take your time, now...then tell me what you see within it..."

Harry bent over the crystal ball and stared, stared as hard as he could, willing it to show him something other than swirling white fog, but nothing happened.

"Well?" Professor Trelawney prompted delicately. "What do you see?"

The heat was overpowering and his nostrils were stinging with the perfumed smoke wafting from the fire beside them. He thought of what Ron had just said, and decided to pretend.

"Er -" said Harry, "a dark shape...um..."

"What does it resemble?" whispered Professor Trelawney. "Think, now..."

Harry cast his mind around and it landed on Buckbeak.

"A Hippogriff," he said firmly.

"Indeed!" whispered Professor Trelawney, scribbling keenly on the parchment perched upon her knees. "My boy, you may well be seeing the outcome of poor Hagrid's trouble with the Ministry of Magic! Look closer...Does the Hippogriff appear to...have its head?"

"Yes," said Harry firmly.

"Are you sure?" Professor Trelawney urged him. "Are you quite sure, dear? You don't see it writhing on the ground, perhaps, and a shadowy figure raising an axe behind it?"

"No!" said Harry, starting to feel slightly sick.

"No blood? No weeping Hagrid?"

"No!" said Harry again, wanting more than ever to leave the room and the heat. "It looks fine, it's - flying away..."

Professor Trelawney sighed.

"Well, dear, I think we'll leave it there...A little disappointing...but I'm sure you did your best."

Relieved, Harry got up, picked up his bag and turned to go, but then a loud, harsh voice spoke behind him.

"IT WILL HAPPEN TONIGHT."

Harry wheeled around. Professor Trelawney had gone rigid in her armchair; her eyes were unfocused and her mouth sagging.

"S - sorry?" said Harry.

But Professor Trelawney didn't seem to hear him. Her eyes started to roll. Harry sat there in a panic. She looked as though she was about to have some sort of seizure. He hesitated, thinking of running to the hospital wing - and then Professor Trelawney spoke again, in the same harsh voice, quite unlike her own:

"THE DARK LORD LIES ALONE AND FRIENDLESS, ABANDONED BY HIS FOLLOWERS. HIS SERVANT HAS BEEN CHAINED THESE TWELVE YEARS. TONIGHT, BEFORE MIDNIGHT...THE SERVANT WILL BREAK FREE AND SET OUT TO REJOIN HIS MASTER. THE DARK LORD WILL RISE AGAIN WITH HIS SERVANT'S AID, GREATER AND MORE TERRIBLE THAN EVER HE WAS. TONIGHT...BEFORE MIDNIGHT...THE SERVANT...WILL SET OUT...TO REJOIN...HIS MASTER..."

Professor Trelawney's head fell forward onto her chest. She made a grunting sort of noise. Harry sat there, staring at her. Then, quite suddenly, Professor Trelawney's head snapped up again.

"I'm so sorry, dear boy," she said dreamily, "the heat of the day, you know...I drifted off for a moment..."

Harry sat there, staring at her.

"Is there anything wrong, my dear?"

"You - you just told me that the - the Dark Lord's going to rise again...that his servant's going to go back to him."

Professor Trelawney looked thoroughly startled.

"The Dark Lord? He-Who-Must-Not-Be-Named? My dear boy, that's hardly something to joke about...Rise again, indeed -"

"But you just said it! You said the Dark Lord -"

"I think you must have dozed off too, dear!" said Professor Trelawney. "I would certainly not presume to predict anything quite as far-fetched as that!"

Harry climbed back down the ladder and the spiral staircase, wondering...had he just heard Professor Trelawney make a real prediction? Or had that been her idea of an impressive end to the test?

Five minutes later he was dashing past the security trolls outside the entrance to Gryffindor Tower, Professor Trelawney's words still resounding in his head. People were striding past him in the opposite direction, laughing and joking, heading for the grounds and a bit of long-awaited freedom; by the time he had reached the portrait hole and entered the common room, it was almost deserted. Over in the corner, however, sat Ron and Hermione.

"Professor Trelawney," Harry panted, "just told me -"

But he stopped abruptly at the sight of their faces.

"Buckbeak lost," said Ron weakly. "Hagrid's just sent this."

Hagrid's note was dry this time, no tears had splattered it, yet his hand seemed to have shaken so much as he wrote that it was hardly legible.

Lost appeal. They're going to execute at sunset. Nothing you can do. Don't come down. I don't want you to see it.
Hagrid
Harry sank down next to Ron and Hermione, thinking hard.

"We've got to go," said Harry at once. "He can't just sit there on his own, waiting for the executioner!"

"Sunset, though," said Ron, who was staring out the window in a glazed sort of way. "We'd never be allowed ...'specially you, Harry..."

Harry sank his head into his hands, thinking.

"If we only had the Invisibility Cloak..."

"Where is it?" said Hermione.

Harry told her about leaving it in the passageway under the one-eyed witch.

"... if Snape sees me anywhere near there again, I'm in serious trouble," he finished.

"That's true," said Hermione, getting to her feet. "If he sees you...How do you open the witch's hump again?"

"You - you tap it and say, 'Dissendium,'" said Harry. "But -"

Hermione didn't wait for the rest of his sentence; she strode across the room, pushed open the Fat Lady's portrait and vanished from sight.

"She hasn't gone to get it?" Ron said, staring after her.

She had. Hermione returned a quarter of an hour later with the silvery cloak folded carefully under her robes.

"Hermione, I don't know what's gotten, into you lately!" said Ron, astounded. "First you hit Malfoy, then you walk out on Professor Trelawney -"

Hermione looked rather flattered.

They went down to dinner with everybody else, but did not return to Gryffindor Tower afterward. Harry had the cloak hidden down the front of his robes; he had to keep his arms folded to hide the lump. They skulked in an empty chamber off the entrance hall, listening, until they were sure it was deserted. Hermione poked her head around the door.

"Okay," she whispered, "no one there - cloak on -"

Walking very close together so that nobody would see them, they crossed the hall on tiptoe beneath the cloak, then walked down the stone front steps into the grounds. The sun was already sinking behind the Forbidden Forest, gilding the top branches of the trees.

They reached Hagrid's cabin and knocked. He was a minute in answering, and when he did, he looked all around for his visitor, pale-faced and trembling.

"It's us," Harry hissed. "We're wearing the Invisibility Cloak. Let us in and we can take it off."

"Yeh shouldn've come!" Hagrid whispered, but he stood back, and they stepped inside. Hagrid shut the door quickly and Harry pulled off the cloak.

Hagrid was not crying, nor did he throw himself upon their necks. He looked like a man who did not know where he was or what to do. This helplessness was worse to watch than tears.

"Wan' some tea?" he said. His great hands were shaking as he reached for the kettle.

"Where's Buckbeak, Hagrid?" said Hermione hesitantly.

"I - I took him outside," said Hagrid, spilling milk all over the table as he filled up the jug. "He's tethered in me pumpkin patch. Thought he oughta see the trees an' - an' smell fresh air - before -"

Hagrid's hand trembled so violently that the milk jug slipped from his grasp and shattered all over the floor. But Harry hardly noticed. He had just thought of an idea.

"I'll do it, Hagrid," said Hermione quickly, hurrying over and starting to clean up the mess.

"There's another one in the cupboard," Hagrid said, sitting down and wiping his forehead on his sleeve. Harry glanced at Ron, who looked back hopelessly.

"Isn't there anything anyone can do, Hagrid?" Harry asked fiercely, sitting down next to him. "Dumbledore -"

"He's tried," said Hagrid. "He's got no power ter overrule the Committee. He told 'em Buckbeak's all right, but they're scared...Yeh know what Lucius Malfoy's like...threatened 'em, I expect...an' the executioner, Macnair, he's an old pal o' Malfoy's...but it'll be quick an' clean...an' I'll be beside him..."

Hagrid swallowed. His eyes were darting all over the cabin as though looking for some shred of hope or comfort.

"Dumbledore's gonna come down while it - while it happens. Wrote me this mornin'. Said he wants ter - ter be with me. Great man, Dumbledore..."

Hermione, who had been rummaging in Hagrid's cupboard for another milk jug, let out a small, quickly stifled sob. She straightened up with the new jug in her hands, fighting back tears.

"We'll stay with you too, Hagrid," she began, but Hagrid shook his shaggy head.

"Yeh're ter go back up ter the castle. I told yeh, I don' wan' yeh watchin'. An' yeh shouldn' be down here anyway...If Fudge an' Dumbledore catch yeh out without permission, Harry, yeh'll be in big trouble."

Silent tears were now streaming down Hermione's face, but she hid them from Hagrid, bustling around making tea. Then, as she picked up the milk bottle to pour some into the jug, she let out a shriek.

"Ron, I don't believe it - it's Scabbers!"

Ron gaped at her.

"What are you talking about?"

Hermione carried the milk jug over to the table and turned it upside down. With a frantic squeak, and much scrambling to get back inside, Scabbers the rat came sliding out onto the table.

"Scabbers!" said Ron blankly. "Scabbers, what are you doing here?"

He grabbed the struggling rat and held him up to the light. Scabbers looked dreadful. He was thinner than ever, large tufts of hair had fallen out leaving wide bald patches, and he writhed in Ron's hands as though desperate to free himself

"It's okay, Scabbers!" said Ron. "No cats! There's nothing here to hurt you!"

Hagrid suddenly stood up, his eyes fixed on the window. His normally ruddy face had gone the color of parchment.

"They're comin'..."

Harry, Ron, and Hermione whipped around. A group of men was walking down the distant castle steps. In front was Albus Dumbledore, his silver beard gleaming in the dying sun. Next to him trotted Cornelius Fudge. Behind them came the feeble old Committee member and the executioner, Macnair.

"Yeh gotta go," said Hagrid. Every inch of him was trembling. "They mustn' find yeh here...Go now..."

Ron stuffed Scabbers into his pocket and Hermione picked up the cloak. "I'll let yeh out the back way," said Hagrid.

They followed him to the door into his back garden. Harry felt very nervous about what he was going to try to do, but he knew he had to. Buckbeak seemed to know something was happening. He turned his sharp head from side to side and pawed the ground nervously.

"It's okay, Beaky," said Hagrid softly. "It's okay..." He turned to Harry, Ron, and Hermione. "Go on," he said. "Get goin'."

As Hermione threw the cloak over Harry and Ron, they heard voices at the front of the cabin. Hagrid looked at the place where they had just vanished from sight.

"Go quick," he said hoarsely. "Don' listen..."

And he strode back into his cabin as someone knocked at the front door.

Ron and Hermione made to walk away from Hagrid's hut.

"No," Harry whispered.

"Harry," said Hermione, in a terrified whisper, "we-"

"Now's our chance to free Buckbeak. Once they've seen he's tied outside, we can quickly untie him, take him into the forest, and they won't be able to blame Hagrid."

"But where can he go?" asked Ron.

"We'll worry about that when we have to," whispered. So the three of them listened intently.

"Where is the beast?" came the cold voice of Macnair.
"Out - outside," Hagrid croaked.

Macnair's face appeared at Hagrid's window, staring out at Buckbeak. Then Fudge spoke.

"We - er - have to read you the official notice of execution, Hagrid. I'll make it quick. And then you and Macnair need to sign it. Macnair, You're supposed to listen too, that's procedure -"

Macnair's face vanished from the window. It was now or never.

"Let's go," whispered, and they slowly walked up to Buckbeak.

"It is the decision of the Committee for the Disposal of Dangerous Creatures that the Hippogriff Buckbeak, hereafter called the condemned, shall he executed on the sixth of June at sundown -"

Harry began to fumble with the knot of rope tying Buckbeak to the fence.

"... sentenced to execution by beheading, to be carried out by the Committee's appointed executioner, Walden Macnair..."

"Come on, Buckbeak," Ron murmured.

"Come on, we're going to help you," said Hermione. "Quietly... quietly..."

"... as witnessed below. Hagrid, you sign here..."

Harry, Ron, and Hermione threw all their weight onto the rope, but Buckbeak had dug in his front feet.

"Well, let's get this over with," said the reedy voice of the Committee member from inside Hagrid's cabin. "Hagrid, perhaps it will be better if you stay inside -"

"No, I - I wan' ter be with him... I don' wan' him ter be alone -"

Footsteps echoed from within the cabin.

"Buckbeak, move!" Harry hissed.

They tugged harder on the rope around Buckbeak's neck. The Hippogriff began to walk, rustling its wings irritably. They were still ten feet away from the forest, in plain view of Hagrid's back door. "One moment, please, Macnair," came Dumbledore's voice. "You need to sign too." The footsteps stopped. Harry heaved on the rope. Buckbeak snapped his beak and walked a little faster.

Harry could still hear Dumbledore's voice talking from within the cabin. He gave the rope another wrench. Buckbeak broke into a grudging trot. They had reached the trees.

Harry looked over his shoulder; they were now blocked from sight; they couldn't see Hagrid's garden at all.

Hagrid's back door had opened with a bang. Harry, Ron, Hermione, and Buckbeak stood quite still; even the Hippogriff seemed to be listening intently. Silence... then -

"Where is it?" said the reedy voice of the Committee member. "Where is the beast?"

"It was tied here!" said the executioner furiously. "I saw it! Just here!"

"How extraordinary," said Dumbledore. There was a note of amusement in his voice.

"Beaky!" said Hagrid huskily.

There was a swishing noise, and the thud of an axe. The executioner seemed to have swung it into the fence in anger. Hagrid gave a howl of pleasure, and started sobbing.

"Gone! Gone! Bless his little beak, he's gone! Musta pulled himself free! Beaky, yeh clever boy!"

Buckbeak started to strain against the rope, trying to get back to Hagrid. Harry, Ron, and Hermione tightened their grip and dug their heels into the forest floor to stop him.

"Someone untied him!" the executioner was snarling. "We should search the grounds, the forest."

"Macnair, if Buckbeak has indeed been stolen, do you really think the thief will have led him away on foot?" said Dumbledore, still sounding amused. "Search the skies, if you will... Hagrid, I could do with a cup of tea. Or a large brandy."

"O' - o' course, Professor," said Hagrid, who sounded weak with happiness. "Come in, come in..."

Harry, Ron, and Hermione listened closely. They heard footsteps, the soft cursing of the executioner, the snap of the door, and then silence once more.

"Now what?" whispered Ron, looking around.

"We'll have to hide in here," said Hermione, who looked very shaken. "We need to wait until they've gone back to the castle. And then we'll take him back to Hagrid's and maybe Hagrid will be able to find a good hiding place for him. Oh, this is going to be difficult..."

"Let's get further away from Hagrid's cabin," Harry whispered.

The three of them began to slowly edge along the perimeter of the forest, making sure to keep Buckbeak out of sight.

Chapter 17

Ron came to a sudden halt.

"Oh please Ron," Hermione Began.

"It's Scabbers - he won't - stay put – OUCH! He bit me!"

"Ron, be quiet!" Hermione whispered urgently. "Fudge'll be out here in a minute -"

"He won't - stay - put -"

Scabbers was plainly terrified. He was writhing with all his might, trying to break free of Ron's grip.

"What's the matter with him?"

But Harry had just seen - slinking toward them, his body low to the ground, wide yellow eyes glinting eerily in the darkness - Crookshanks. Whether he could see them or was following the sound of Scabbers's squeaks, Harry couldn't tell.

"Crookshanks!" Hermione moaned. "No, go away, Crookshanks! Go away!"

But the cat was getting nearer -

"Scabbers - NO!"

Too late - the rat had slipped between Ron's clutching fingers, hit the ground, and scampered away. In one bound, Crookshanks sprang after him, and before Harry or Hermione could stop him, Ron had thrown the Invisibility Cloak off himself, let go of the rope, and pelted out of the forest and into the darkness.

"Ron!" Hermione moaned.

"We'll tie him up for now," said Harry. "They'll never find him here." Quickly, Harry and Hermione tied Buckbeak to the nearest tree, then ran out of the forest after Ron.

It was impossible to run full out under the cloak; they pulled it off and it streamed behind them like a banner as they hurtled after Ron; they could hear his feet thundering along ahead and his shouts at Crookshanks.

"Get away from him - get away - Scabbers, come here -"

There was a loud thud.

"Gotcha! Get off, you stinking cat -"

Harry and Hermione almost fell over Ron; they skidded to a stop right in front of him. He was sprawled on the ground, but Scabbers was back in his pocket; he had both hands held tight over the quivering lump.

"Ron - come on back under the cloak -" Hermione panted. "Dumbledore - the Minister - they'll be coming back out in a minute – We have to get back to Buckbeak."

But before they could cover themselves again, before they could even catch their breath, they heard the soft pounding of gigantic paws... Something was bounding toward them, quiet as a shadow - an enormous, pale-eyed, jet-black dog.

Harry reached for his wand, but too late - the dog had made an enormous leap and the front paws hit him on the chest; he keeled over backward in a whirl of hair; he felt its hot breath, saw inch-long teeth -

But the force of its leap had carried it too far; it rolled off him. Dazed, feeling as though his ribs were broken, Harry tried to stand up; he could hear it growling as it skidded around for a new attack.

Ron was on his feet. As the dog sprang back toward them he pushed Harry aside; the dog's jaws fastened instead around Ron's outstretched arm. Harry lunged forward, he seized a handful of the brute's hair, but it was dragging Ron away as easily as though he were a rag doll -

Then, out of nowhere, something hit Harry so hard across the face he was knocked off his feet again. He heard Hermione shriek with pain and fall too.

Harry groped for his wand, blinking blood out of his eyes

"Lumos!" he whispered.

The wandlight showed him the trunk of a thick tree; they had chased Scabbers into the shadow of the Whomping Willow and its branches were creaking as though in a high wind, whipping backward and forward to stop them going nearer.

And there, at the base of the trunk, was the dog, dragging Ron backward into a large gap in the roots - Ron was fighting furiously, but his head and torso were slipping out of sight -

"Ron!" Harry shouted, trying to follow, but a heavy branch whipped lethally through the air and he was forced backward again.

All they could see now was one of Ron's legs, which he had hooked around a root in an effort to stop the dog from pulling him farther underground - but a horrible crack cut the air like a gunshot; Ron's leg had broken, and a moment later, his foot vanished from sight.

"Harry - we've got to go for help -" Hermione gasped; she was bleeding too; the Willow had cut her across the shoulder.

"No! That thing's big enough to eat him; we haven't got time -"

"Harry - we're never going to get through without help -"

Another branch whipped down at them, twigs clenched like knuckles.

"If that dog can get in, we can," Harry panted, darting here and there, trying to find a way through the vicious, swishing branches, but he couldn't get an inch nearer to the tree roots without being in range of the tree's blows.

"Oh, help, help," Hermione whispered frantically, dancing uncertainly on the spot, "Please..."

Crookshanks darted forward. He slithered between the battering branches like a snake and placed his front paws upon a knot on the trunk.

Abruptly, as though the tree had been turned to marble, it stopped moving. Not a leaf twitched or shook.

"Crookshanks!" Hermione whispered uncertainly. She now grasped Harry's arm painfully hard. "How did he know -?"

"He's friends with that dog," said Harry grimly. "I've seen them together. Come on - and keep your wand out -"

They covered the distance to the trunk in seconds, but before they had reached the gap in the roots, Crookshanks had slid into it with a flick of his bottlebrush tail. Harry went next; he crawled forward, headfirst, and slid down an earthy slope to the bottom of a very low tunnel. Crookshanks was a little way along, his eyes flashing in the light from Harry's wand. Seconds later, Hermione slithered down beside him.

"Where's Ron?" she whispered in a terrified voice.

"This way," said Harry, setting off, bent-backed, after Crookshanks.

"Where does this tunnel come out?" Hermione asked breathlessly from behind him.

"I don't know...It's marked on the Marauder's Map but Fred and George said no one's ever gotten into it...It goes off the edge of the map, but it looked like it was heading for Hogsmeade..."

They moved as fast as they could, bent almost double; ahead of them, Crookshanks's tail bobbed in and out of view. On and on went the passage; it felt at least as long as the one to Honeydukes... All Harry could think of was Ron and what the enormous dog might be doing to him...He was drawing breath in sharp, painful gasps, running at a crouch...

And then the tunnel began to rise; moments later it twisted, and Crookshanks had gone. Ahead Harry could see a patch of dim light through a small opening.

He and Hermione paused, gasping for breath, edging forward. Both raised their wands to see what lay beyond.

It was a room, a very disordered, dusty room. Paper was peeling from the walls; there were stains all over the floor; every piece of furniture was broken as though somebody had smashed it. The windows were all boarded up.

Harry glanced at Hermione, who looked very frightened but nodded.

Harry pulled himself out of the hole, staring around. The room was deserted, but a door to their right stood open, leading to a shadowy hallway. Hermione suddenly grabbed Harry's arm again. Her wide eyes were traveling around the boarded windows.

"Harry," she whispered, "I think we're in the Shrieking Shack."

Harry looked around. His eyes fell on a wooden chair near them. Large chunks had been torn out of it; one of the legs had been ripped off entirely.

"Ghosts didn't do that," he said slowly.

At that moment, there was a creak overhead. Something had moved upstairs. Both of them looked up at the ceiling. Hermione's grip on Harry's arm was so tight he was losing feeling in his fingers. He raised his eyebrows at her; she nodded again and let go.

Quietly as they could, they crept out into the hall and up the crumbling staircase. Everything was covered in a thick layer of dust except the floor, where a wide shiny stripe had been made by something being dragged upstairs.

They reached the dark landing.

"Nox," they whispered together, and the lights at the end of their wands went out. Only one door was open. As they crept toward it, they heard movement from behind it; a low moan, and then a deep, loud purring. They exchanged a last look, a last nod.

Wand held tightly before him, Harry kicked the door wide open.

On a magnificent four-poster bed with dusty hangings lay Crookshanks, purring loudly at the sight of them. On the floor beside him, clutching his leg, which stuck out at a strange angle, was Ron.

Harry and Hermione dashed across to him.

"Ron - are you okay?"

"Where's the dog?"

"Not a dog," Ron moaned. His teeth were gritted with pain. "Harry, it's a trap -"

"What -"

"He's the dog...he's an Animagus."

Ron was staring over Harry's shoulder. Harry wheeled around. With a snap, the man in the shadows closed the door behind them.

A mass of filthy, matted hair hung to his elbows. If eyes hadn't been shining out of the deep, dark sockets, he might have been a corpse. The waxy skin was stretched so tightly over the bones of his face, it looked like a skull. His yellow teeth were bared in a grin. It was Sirius Black.

"Expelliarmus!" he croaked, pointing Ron's wand at them.

Harry's and Hermione's wands shot out of their hands, high in the air, and Black caught them. Then he took a step closer. His eyes were fixed on Harry.

"I thought you'd come and help your friend," he said hoarsely.

His voice sounded as though he had long since lost the habit of using it. "Your father would have done the same for me. Brave of you not to run for a teacher. I'm grateful...it will make everything much easier..."

The taunt about his father rang in Harry's ears as though Black had bellowed it. A boiling hate erupted in Harry's chest, leaving no place for fear. For the first time in his life, he wanted his wand back in his hand, not to defend himself, but to attack...to kill. Without knowing what he was doing, he started forward, but there was a sudden movement on either side of him and two pairs of hands grabbed him and held him back... "No, Harry!" Hermione gasped in a petrified whisper; Ron, however, spoke to Black.

"If you want to kill Harry, you'll have to kill us too!" he said fiercely, though the effort of standing upright was draining him of still more color, and he swayed slightly as he spoke.

Something flickered in Black's shadowed eyes.

"Lie down," he said quietly to Ron. "You will damage that leg even more."

"Did you hear me?" Ron said weakly, though he was clinging painfully to Harry to stay upright. "You'll have to kill all three of us!"

"There'll be only one murder here tonight," said Black, and his grin widened.

"Why's that?" Harry spat, trying to wrench himself free of Ron, and Hermione. "Didn't care last time, did you? Didn't mind slaughtering all those Muggles to get at Pettigrew...What's the matter, gone soft in Azkaban?"

"Harry!" Hermione whimpered. "Be quiet!"

"HE KILLED MY MUM AND DAD!" Harry roared, and with a huge effort he broke free of Hermione's and Ron's restraint and lunged forward -

He had forgotten about magic - he had forgotten that he was short and skinny and thirteen, whereas Black was a tall, full-grown man - all Harry knew was that he wanted to hurt Black as badly as he could and that he didn't care how much he got hurt in return -

Perhaps it was the shock of Harry doing something so stupid, but Black didn't raise the wands in time - one of Harry's hands fastened over his wasted wrist, forcing the wand tips away; the knuckles of Harry's other hand collided with the side of Black's head and they fell, backward, into the wall -

Hermione was screaming; Ron was yelling; there was a blinding flash as the wands in Black's hand sent a jet of sparks into the air that missed Harry's face by inches; Harry felt the shrunken arm under his fingers twisting madly, but he clung on, his other hand punching every part of Black it could find.

But Black's free hand had found Harry's throat

"No," he hissed, "I've waited too long -"

The fingers tightened, Harry choked, his glasses askew.

Then he saw Hermione's foot swing out of nowhere. Black let go of Harry with a grunt of pain; Ron had thrown himself on Black's wand hand and Harry heard a faint clatter -

He fought free of the tangle of bodies and saw his own wand rolling across the floor; he threw himself toward it but

"Argh!"

Crookshanks had joined the fray; both sets of front claws had sunk themselves deep into Harry's arm; Harry threw him off, but Crookshanks now darted toward Harry's wand -

"NO YOU DON'T!" roared Harry, and he aimed a kick at Crookshanks that made the cat leap aside, spitting; Harry snatched up his wand and turned -

"Get out of the way!" he shouted at Ron and Hermione.

They didn't need telling twice. Hermione, gasping for breath, her lip bleeding, scrambled aside, snatching up her and Ron's wands. Ron crawled to the four-poster and collapsed onto it, panting, his white face now tinged with green, both hands clutching his broken leg.

Black was sprawled at the bottom of the wall. His thin chest rose and fell rapidly as he watched Harry walking slowly nearer, his wand pointing straight at Black's heart.

"Going to kill me, Harry?" he whispered.

Harry stopped right above him, his wand still pointing at Black's chest, looking down at him. A livid bruise was rising around Black's left eye and his nose was bleeding.

"You killed my parents," said Harry, his voice shaking slightly, but his wand hand quite steady.

Black stared up at him out of those sunken eyes.

"I don't deny it," he said very quietly. "But if you knew the whole story."

"The whole story?" Harry repeated, a furious pounding in his ears. "You sold them to Voldemort. That's all I need to know."

"You've got to listen to me," Black said, and there was a note of urgency in his voice now. "You'll regret it if you don't...You don't understand..."

"I understand a lot better than you think," said Harry, and his voice shook more than ever. "You never heard her, did you? My mum...trying to stop Voldemort killing me...and you did that...you did it..."

Before either of them could say another word, something ginger streaked past Harry; Crookshanks leapt onto Black's chest and settled himself there, right over Black's heart. Black blinked and looked down at the cat.

"Get off," he murmured, trying to push Crookshanks off him.

But Crookshanks sank his claws into Black's robes and wouldn't shift. He turned his ugly, squashed face to Harry and looked up at him with those great yellow eyes. To his right, Hermione gave a dry sob.

Harry stared down at Black and Crookshanks, his grip tightening on the wand. So what if he had to kill the cat too? It was in league with Black...If it was prepared to die, trying to protect Black, that wasn't Harry's business... If Black wanted to save it, that only proved he cared more for Crookshanks than for Harry's parents...

Harry raised the wand. Now was the moment to do it. Now was the moment to avenge his mother and father. He was going to kill Black. He had to kill Black. This was his chance...

The seconds lengthened. And still Harry stood frozen there, wand poised, Black staring up at him, Crookshanks on his chest. Ron's ragged breathing came from near the bed; Hermione was quite silent.

And then came a new sound -

Muffled footsteps were echoing up through the floor - someone was moving downstairs.

"WE'RE UP HERE!" Hermione screamed suddenly. "WE'RE UP HERE - SIRIUS BLACK - QUICK!"

Black made a startled movement that almost dislodged Crookshanks; Harry gripped his wand convulsively - Do it now! said a voice in his head - but the footsteps were thundering up the stairs and Harry still hadn't done it.

The door of the room burst open in a shower of red sparks and Harry wheeled around as Professor Lupin came hurtling into the room, his face bloodless, his wand raised and ready. His eyes flickered over Ron, lying on the floor, over Hermione, cowering next to the door, to Harry, standing there with his wand covering Black, and then to Black himself, crumpled and bleeding at Harry's feet.

"Expelliarmus!" Lupin shouted.

Harry's wand flew once more out of his hand; so did the two Hermione was holding. Lupin caught them all deftly, then moved into the room, staring at Black, who still had Crookshanks lying protectively across his chest.

Harry stood there, feeling suddenly empty. He hadn't done it. His nerve had failed him. Black was going to be handed back to the Dementors.

Then Lupin spoke, in a very tense voice.

"Where is he, Sirius?"

Harry looked quickly at Lupin. He didn't understand what Lupin meant. Who was Lupin talking about? He turned to look at Black again.

Black's face was quite expressionless. For a few seconds, he didn't move at all. Then, very slowly, he raised his empty hand and pointed straight at Ron. Mystified, Harry glanced around at Ron, who looked bewildered.

"But then..." Lupin muttered, staring at Black so intently it seemed he was trying to read his mind, "...why hasn't he shown himself before now? Unless" - Lupin's eyes suddenly widened, as though he was seeing something beyond Black, something none of the rest could see, "- unless he was the one...unless you switched... without telling me?"

Very slowly, his sunken gaze never leaving Lupin's face, Black nodded.

"Professor," Harry interrupted loudly, "what's going on -?"

But he never finished the question, because what he saw made his voice die in his throat. Lupin was lowering his wand, gazing fixed at Black. The Professor walked to Black's side, seized his hand, pulled him to his feet so that Crookshanks fell to the floor, and embraced Black like a brother.

Harry felt as though the bottom had dropped out of his stomach.

"I DON'T BELIEVE IT!" Hermione screamed.

Lupin let go of Black and turned to her. She had raised herself off the floor and was pointing at Lupin, wild-eyed. "You - you -"

"Hermione -"

"¨C you and him!"

"Hermione, calm down -"

"I didn't tell anyone!" Hermione shrieked. "I've been covering up for you -"

"Hermione, listen to me, please" Lupin shouted. "I can explain -"

Harry could feel himself shaking, not with fear, but with a fresh wave of fury.

"I trusted you," he shouted at Lupin, his voice wavering, out of control, "and all the time you've been his friend!"

"You're wrong," said Lupin. "I haven't been Sirius's friend, but I am now - Let me explain..."

"NO!" Hermione screamed. "Harry, don't trust him, he's been helping Black get into the castle, he wants you dead too - he's a werewolf!"

There was a ringing silence. Everyone's eyes were now on Lupin, who looked remarkably calm, though rather pale.

"Not at all up to your usual standard, Hermione," he said. "Only one out of three, I'm afraid. I have not been helping Sirius get into the castle and I certainly don't want Harry dead. An odd shiver passed over his face. "But I won't deny that I am a werewolf."

Ron made a valiant effort to get up again but fell back with a whimper of pain. Lupin made toward him, looking concerned, but Ron gasped, "Get away from me, werewolf!"

Lupin stopped dead. Then, with an obvious effort, he turned to Hermione and said, "How long have you known?"

"Ages," Hermione whispered. "Since I did Professor Snape's essay..."

"He'll be delighted," said Lupin coolly. "He assigned that essay hoping someone would realize what my symptoms meant... Did you check the lunar chart and realize that I was always ill at the full moon? Or did you realize that the Boggart changed into the moon when it saw me?"

"Both," Hermione said quietly.

Lupin forced a laugh.

"You're the cleverest witch of your age I've ever met, Hermione."

"I'm not," Hermione whispered. "If I'd been a bit cleverer, I'd have told everyone what you are!"

"But they already know," said Lupin. "At least, the staff do."

"Dumbledore hired you when he knew you were a werewolf," Ron gasped. "Is he mad?"

"Some of the staff thought so," said Lupin. "He had to work very hard to convince certain teachers that I'm trustworthy -"

"AND HE WAS WRONG!" Harry yelled. "YOU'VE BEEN HELPING HIM ALL THE TIME!" He was pointing at Black, who suddenly crossed to the four-poster bed and sank onto it, his face hidden in one shaking hand. Crookshanks leapt up beside him and stepped onto his lap, purring. Ron edged away from both of them, dragging his leg.

"I have not been helping Sirius," said Lupin. "If you'll give me a chance, I'll explain. Look -"

He separated Harry's, Ron's and Hermione's wands and threw each back to its owner; Harry caught his, stunned.

"There," said Lupin, sticking his own wand back into his belt "You're armed, we're not. Now will you listen?"

Harry didn't know what to think. Was it a trick?

"If you haven't been helping him," he said, with a furious glance at Black, "how did you know he was here?"

"The map," said Lupin. "The Marauder's Map. I was in my office examining it -"

"You know how to work it?" Harry said suspiciously.

"Of course I know how to work it," said Lupin, waving his hand impatiently. "I helped write it. I'm Moony - that was my friends' nickname for me at school."

"You wrote -?"

"The important thing is, I was watching it carefully this evening, because I had an idea that you, Ron, and Hermione might try and sneak out of the castle to visit Hagrid before his Hippogriff was executed. And I was right, wasn't I?"

He had started to pace up and down, looking at them. Little patches of dust rose at his feet.

"You might have been wearing your father's old cloak, Harry-"

"How d'you know about the cloak?"

"The number of times I saw James disappearing under it..." said Lupin, waving an impatient hand again. "The point is, even if you're wearing an Invisibility Cloak, you still show up on the Marauder's Map. I watched you cross the grounds and enter Hagrid's hut. Twenty minutes later, you left Hagrid, and set off back toward the castle. But you were now accompanied by somebody else."

"What?" said Harry. "No, we weren't!"

"I couldn't believe my eyes,' said Lupin, still pacing, and ignoring Harry's interruption. "I thought the map must be malfunctioning. How could he be with you?"

"No one was with us!" said Harry.

"And then I saw another dot, moving fast toward you, labeled Sirius Black...I saw him collide with you; I watched as he pulled two of you into the Whomping Willow -"

"One of us!" Ron said angrily.

"No, Ron," said Lupin. "Two of you."

He had stopped his pacing, his eyes moving over Ron.

"Do you think I could have a look at the rat?" he said evenly.

"What?" said Ron. "What's Scabbers got to do with it?"

"Everything," said Lupin. "Could I see him, please?"

Ron hesitated, then put a hand inside his robes. Scabbers emerged, thrashing desperately; Ron had to seize his long bald tail to stop him escaping. Crookshanks stood up on Black's leg and made a soft hissing noise.

Lupin moved closer to Ron. He seemed to be holding his breath as he gazed intently at Scabbers.

"What?" Ron said again, holding Scabbers close to him, looking scared. "What's my rat got to do with anything?"

"That's not a rat," croaked Sirius Black suddenly.

"What d'you mean - of course he's a rat -"

"No, he's not," said Lupin quietly. "He's a wizard."

"An Animagus," said Black, "by the name of Peter Pettigrew."

Chapter 18

It took a few seconds for the absurdity of this statement to sink in. Then Ron voiced what Harry was thinking.

"You're both mental."

"Ridiculous!" said Hermione faintly.

"Peter Pettigrew's dead!" said Harry. "He killed him twelve years ago!" He pointed at Black, whose face twitched convulsively.

"I meant to," he growled, his yellow teeth bared, "but little Peter got the better of me...not this time, though!"

And Crookshanks was thrown to the floor as Black lunged at Scabbers; Ron yelled with pain as Black's weight fell on his broken leg.

"Sirius, NO!" Lupin yelled, launching himself forwards and dragging Black away from Ron again, "WAIT! You can't do it just like that - they need to understand - we've got to explain -"

"We can explain afterwards!" snarled Black, trying to throw Lupin off. One hand was still clawing the air as it tried to reach Scabbers, who was squealing like a piglet, scratching Ron's face and neck as he tried to escape.

"They've - got - a - right - to - know - everything!" Lupin panted, still trying to restrain Black. "Ron's kept him as a pet! There are parts of it even I don't understand, and Harry - you owe Harry the truth, Sirius!"

Black stopped struggling, though his hollowed eyes were still fixed on Scabbers, who was clamped tightly under Ron's bitten, scratched, and bleeding hands.

"All right, then," Black said, without taking his eyes off the rat.

"Tell them whatever you like. But make it quick, Remus. I want to commit the murder I was imprisoned for..."

"You're nutters, both of you," said Ron shakily, looking round at Harry and Hermione for support. "I've had enough of this. I'm off."

He tried to heave himself up on his good leg, but Lupin raised his wand again, pointing it at Scabbers.

"You're going to hear me out, Ron," he said quietly. "Just keep a tight hold on Peter while you listen."

"HE'S NOT PETER, HE'S SCABBERS!" Ron yelled, trying to force the rat back into his front pocket, but Scabbers was fighting too hard; Ron swayed and overbalanced, and Harry caught him am pushed him back down to the bed. Then, ignoring Black, Harry turned to Lupin.

"There were witnesses who saw Pettigrew die," he said. "A whole street full of them..."

"They didn't see what they thought they saw!" said Black savagely, still watching Scabbers struggling in Ron's hands.

"Everyone thought Sirius killed Peter," said Lupin, nodding. "I believed it myself - until I saw the map tonight. Because the Marauder's map never lies...Peter's alive. Ron's holding him, Harry."

Harry looked down at Ron, and as their eyes met, they agreed, silently: Black and Lupin were both out of their minds. Their story made no sense whatsoever. How could Scabbers be Peter Pettigrew? Azkaban must have unhinged Black after all - but why was Lupin playing along with him?

Then Hermione spoke, in a trembling, would-be calm sort of voice, as though trying to will Professor Lupin to talk sensibly.

"But Professor Lupin...Scabbers can't be Pettigrew...it just can't be true, you know it can't..."

"Why can't it be true?" Lupin said calmly, as though they were in class, and Hermione had simply spotted a problem in an experiment with Grindylows.

"Because... because people would know if Peter Pettigrew had been an Animagus. We did Animagi in class with Professor McGonagall. And I looked them up when I did my homework - the Ministry of Magic keeps tabs on witches and wizards who can become animals; there's a register showing what animal they become, and their markings and things...and I went and looked Professor McGonagall up on the register, and there have been only seven Animagi this century, and Pettigrew's name wasn't on the list."

Harry had barely had time to marvel inwardly at the effort Hermione put into her homework, when Lupin started to laugh.

"Right again, Hermione!" he said. "But the Ministry never knew that here used to be three unregistered Animagi running around Hogwarts."

"If you're going to tell them the story, get a move on, Remus," said Black, who was still watching Scabbers's every desperate move. "I've waited twelve years, I'm not going to wait much longer."

"All right...but you'll need to help me, Sirius," said Lupin, "I only know how it began..."

Lupin broke off. There had been a loud creak behind him. The bedroom door had opened of its own accord. All five of them stared at it. Then Lupin strode toward it and looked out into the landing.

"No one there..."

"This place is haunted!" said Ron.

"It's not,' said Lupin, still looking at the door in a puzzled way. "The Shrieking Shack was never haunted...The screams and howls the villagers used to hear were made by me."

He pushed his graying hair out of his eyes, thought for a moment then said, "That's where all of this starts - with my becoming a werewolf, None of this could have happened if I hadn't been bitter...and if I hadn't been so foolhardy..."

He looked sober and tired. Ron started to interrupt, but Hermione, said, "Shh!" She was watching Lupin very intently.

"I as a very small boy when I received the bite. My parents tried everything, but in those days there was no cure. The potion that Professor Snape has been making for me is a very recent discovery. It makes me safe, you see. As long as I take it in the week, preceding the full moon, I keep my mind when I transform...I'm able to curl up in my office, a harmless wolf, and wait for the moon to wane again.

"Before the Wolfsbane Potion was discovered, however, I became a fully fledged monster once a month. It seemed impossible that I would be able to come to Hogwarts. Other parents weren't likely to want their children exposed to me.

"But then Dumbledore became Headmaster, and he was sympathetic. He said that as long as we took certain precautions, there was no reason I shouldn't come to school..." Lupin sighed, and looked directly at Harry. "I told you, months ago, that the Whomping Willow was planted the year I came to Hogwarts. The truth is that it was planted because I came to Hogwarts. This house" - Lupin looked miserably around the room, - "the tunnel that leads to it - they were built for my use. Once a month, I was smuggled out of the castle, into this place, to transform. The tree was placed at the tunnel mouth to stop anyone coming across me while I was dangerous."

Harry couldn't see where this story was going, but he was listening raptly all the same. The only sound apart from Lupin's voice was Scabbers's frightened squeaking.

"My transformations in those days were - were terrible. It is very painful to turn into a werewolf. I was separated from humans to bite, so I bit and scratched myself instead. The villagers heard the noise and the screaming and thought they were hearing particularly violent spirits. Dumbledore encouraged the rumor...Even now, when the house has been silent for years, the villagers don't dare approach it..."

"But apart from my transformations, I was happier than I had ever been in my life. For the first time ever, I had friends, three great friends. Sirius Black...Peter Pettigrew...and, of course, your father, Harry - James Potter."

"Now, my three friends could hardly fail to notice that I disappeared once a month. I made up all sorts of stories. I told them my mother was ill, and that I had to go home to see her...I was terrified they would desert me the moment they found out what I was. But of course, they, like you, Hermione, worked out the truth..."

"And they didn't desert me at all. Instead, they did something for me that would make my transformations not only bearable, but the best times of my life. They became Animagi."

"My dad too?" said Harry, astounded.

"Yes, indeed," said Lupin. "It took them the best part of three years to work out how to do it. Your father and Sirius here were the cleverest students in the school, and lucky they were, because the Animagus transformation can go horribly wrong - one reason the Ministry keeps a close watch on those attempting to do it. Peter needed all the help he could get from James and Sirius. Finally, in our fifth year, they managed it. They could each turn into a different animal at will."

"But how did that help you?" said Hermione, sounding puzzled.

"They couldn't keep me company as humans, so they kept me company as animals," said Lupin. "A werewolf is only a danger to people. They sneaked out of the castle every month under James's Invisibility Cloak. They transformed...Peter, as the smallest, could slip beneath the Willow's attacking branches and touch the knot that freezes it. They would then slip down the tunnel and join me. Under their influence, I became less dangerous. My body was still wolfish, but my mind seemed to become less so while I was with them."

"Hurry up, Remus," snarled Black, who was still watching Scabbers with a horrible sort of hunger on his face.

"I'm getting there, Sirius, I'm getting there...well, highly exciting possibilities were open to us now that we could all transform. Soon we were leaving the Shrieking Shack and roaming the school grounds and the village by night. Sirius and James transformed into such large animals, they were able to keep a werewolf in check. I doubt whether any Hogwarts students ever found out more about the Hogwarts grounds and Hogsmeade than we did... And that's how we came to write the Marauder's Map, and sign it with our nicknames. Sirius is Padfoot. Peter is Wormtail. James was Prongs."

"What sort of animal -?" Harry began, but Hermione cut him off. "That was still really dangerous! Running around in the dark with a werewolf! What if you'd given the others the slip, and bitten somebody?"

"A thought that still haunts me," said Lupin heavily. "And there were near misses, many of them. We laughed about them afterwards. We were young, thoughtless - carried away with our own cleverness."

"I sometimes felt guilty about betraying Dumbledore's trust, of course...he had admitted me to Hogwarts when no other headmaster would have done so, and he had no idea I was breaking the rules he had set down for my own and others' safety. He never knew I had led three fellow students into becoming Animagi illegally. But I always managed to forget my guilty feelings every time we sat down to plan our next month's adventure. And I haven't changed..."

Lupin's face had hardened, and there was self-disgust in his voice. "All this year, I have been battling with myself, wondering whether I should tell Dumbledore that Sirius was an Animagus. But I didn't do it. Why? Because I was too cowardly. It would have meant admitting that I'd betrayed his trust while I was at school, admitting that I'd led others along with me...and Dumbledore's trust has meant everything to me. He let me into Hogwarts as a boy, and he gave me a job when I have been shunned all my adult life, unable to find paid work because of what I am. And so I convinced myself that Sirius was getting into the school using dark arts he learned from Voldemort, that being an Animagus had nothing to do with it...so, in a way, Snape's been right about me all along."

"Snape?" said Black harshly, taking his eyes off Scabbers; for the first time in minutes and looking up at Lupin. "What's Snape got to do with it?"

"He's here, Sirius," said Lupin heavily. "He's teaching here as well." He looked up at Harry, Ron, and Hermione.

"Professor Snape was at school with us. He fought very hard against my appointment to the Defense Against the Dark Arts job. He has been telling Dumbledore all year that I am not to be trusted. He has his reasons...you see, Sirius here played a trick on him which nearly killed him, a trick which involved me -"

Black made a derisive noise.

"It served him right," he sneered. "Sneaking around, trying to find out what we were up to...hoping he could get us expelled..."

"Severus was very interested in where I went every month." Lupin told Harry, Ron, and Hermione. "We were in the same year, you know, and we - er - didn't like each other very much. He especially disliked James. Jealous, I think, of James's talent on the Quidditch field...anyway Snape had seen me crossing the grounds with Madam Pomfrey one evening as she led me toward the Whomping Willow to transform. Sirius thought it would be - er - amusing, to tell Snape all he had to do was prod the knot on the tree trunk with a long stick, and he'd be able to get in after me. Well, of course, Snape tried it - if he'd got as far as this house, he'd have met a fully grown werewolf - but your father, who'd heard what Sirius had done, went after Snape and pulled him back, at great risk to his life...Snape glimpsed me, though, at the end of the tunnel. He was forbidden by Dumbledore to tell anybody, but from that time on he knew what I was..."

"So that's why Snape doesn't like you," said Harry slowly, "because he thought you were in on the joke?"

"That's right," sneered a cold voice from the wall behind Lupin.

Severus Snape was pulling off the Invisibility Cloak, his wand pointing directly at Lupin.

Chapter 19

Hermione screamed. Black leapt to his feet. Harry felt as though he'd received a huge electric shock.

"I found this at the base of the Whomping Willow," said Snape, throwing the cloak aside, careful to keep this wand pointing directly at Lupin's chest. "Very useful, Potter, I thank you..."

Snape was slightly breathless, but his face was full of suppressed triumph. "You're wondering, perhaps, how I knew you were here?" he said, his eyes glittering. "I've just been to your office, Lupin. You forgot to take your potion tonight, so I took a gobletful along. And very lucky I did...lucky for me, I mean. Lying on your desk was a certain map. One glance at it told me all I needed to know. I saw you running along this passageway and out of sight."

"Severus -" Lupin began, but Snape overrode him.

"I've told the headmaster again and again that you're helping your old friend Black into the castle, Lupin, and here's the proof. Not even I dreamed you would have the nerve to use this old place as your hideout -"

"Severus, you're making a mistake," said Lupin urgently. "You haven't heard everything - I can explain - Sirius is not here to kill Harry -"

"Two more for Azkaban tonight," said Snape, his eyes now gleaming fanatically. "I shall be interested to see how Dumbledore takes this...He was quite convinced you were harmless, you know, Lupin...a tame werewolf -"

"You fool," said Lupin softly. "Is a schoolboy grudge worth putting an innocent man back inside Azkaban?"

BANG! Thin, snakelike cords burst from the end of Snape's wand and twisted themselves around Lupin's mouth, wrists, and ankles; he overbalanced and fell to the floor, unable to move. With a roar of rage, Black started toward Snape, but Snape pointed his wand straight between Black's eyes.

"Give me a reason," he whispered. "Give me a reason to do it, and I swear I will."

Black stopped dead. It would have been impossible to say which face showed more hatred.

Harry stood there, paralyzed, not knowing what to do or whom to believe. He glanced around at Ron and Hermione. Ron looked just as confused as he did, still fighting to keep hold on the struggling Scabbers. Hermione, however, took an uncertain step toward Snape and said, in a very breathless voice, "Professor Snape - it wouldn't hurt to hear what they've got to say, w-would it?"

"Miss Granger, you are already facing suspension from this school," Snape spat. "You, Potter, and Weasley are out-of-bounds, in the company of a convicted murderer and a werewolf. For once in your life, hold your tongue."

"But if - if there was a mistake -"

"KEEP QUIET, YOU STUPID GIRL!" Snape shouted, looking suddenly quite deranged. "DON'T TALK ABOUT WHAT YOU DON'T UNDERSTAND!" A few sparks shot out of the end of his wand, which was still pointed at Black's face. Hermione fell silent.

"Vengeance is very sweet," Snape breathed at Black. "How I hoped I would be the one to catch you..."

"The joke's on you again, Severus," Black snarled. "As long as this boy brings his rat up to the castle" - he jerked his head at Ron - "I'll come quietly..."

"Up to the castle?" said Snape silkily. "I don't think we need to go that far. All I have to do is call the Dementors once we get out of the Willow. They'll be very pleased to see you, Black...pleased enough to give you a little kiss, I daresay...I -"

What little color there was in Black's face left it.

"You -you've got to hear me out," he croaked. "The rat - look at the rat -"

But there was a mad glint in Snape's eyes that Harry had never seen before. He seemed beyond reason.

"Come on, all of you," he said. He clicked his fingers, and the ends of the cords that bound Lupin flew to his hands. "I'll drag the werewolf. Perhaps the Dementors will have a kiss for him too -"

Before he knew what he was doing, Harry had crossed the room in three strides and blocked the door.

"Get out of the way, Potter, you're in enough trouble already," snarled Snape. "If I hadn't been here to save your skin -"

"Professor Lupin could have killed me about a hundred times this year," Harry said. "I've been alone with him loads of times, having defense lessons against the Dementors. If he was helping Black, why didn't he just finish me off then?"

"Don't ask me to fathom the way a werewolf's mind works," hissed Snape. "Get out of the way, Potter."

"YOU'RE PATHETIC!" Harry yelled. "JUST BECAUSE THEY MADE A FOOL OF YOU AT SCHOOL YOU WON'T EVEN LISTEN -"

"SILENCE! I WILL NOT BE SPOKEN TO LIKE THAT!" Snape shrieked, looking madder than ever. "Like father, like son, Potter! I have just saved your neck; you should be thanking me on bended knee! You would have been well served if he'd killed you! You'd have died like your father, too arrogant to believe you might be mistaken in Black - now get out of the way, or I will make you. GET OUT OF THE WAY, POTTER!"

Harry made up his mind in a split second. Before Snape could take even one step toward him, he had raised his wand.

"Expelliarmus!" he yelled - except that his wasn't the only voice that shouted. There was a blast that made the door rattle on its hinges; Snape was lifted off his feet and slammed into the wall, then slid down it to the floor, a trickle of blood oozing from under his hair. He had been knocked out.

Harry looked around. Both Ron and Hermione had tried to disarm Snape at exactly the same moment. Snape's wand soared in a high arc and landed on the bed next to Crookshanks.

"You shouldn't have done that," said Black, looking at Harry.

"You should have left him to me..."

Harry avoided Black's eyes. He wasn't sure, even now, that he'd done the right thing.

"We attacked a teacher...We attacked a teacher..." Hermione whimpered, staring at the lifeless Snape with frightened eyes. "Oh, we're going to be in so much trouble -"

Lupin was struggling against his bonds. Black bent down quickly and untied him. Lupin straightened up, rubbing his arms where the ropes had cut into them.

"Thank you, Harry," he said.

"I'm still not saying I believe you," he told Lupin.

"Then it's time we offered you some proof," said Lupin. "You, boy - give me Peter, please. Now."

Ron clutched Scabbers closer to his chest.

"Come off it," he said weakly. "Are you trying to say he broke out of Azkaban just to get his hands on Scabbers? I mean..." He looked up at Harry and Hermione for support, "Okay, say Pettigrew could turn into a rat - there are millions of rats - how's he supposed to know which one he is after if he was locked up in Azkaban?"

"You know, Sirius, that's a fair question," said Lupin, turning to Black and frowning slightly. "How did you find out where he was?"

Black put one of his claw-like hands inside his robes and took out a crumpled piece of paper, which he smoothed flat and held out to show the others.

It was the photograph of Ron and his family that had appeared in the Daily Prophet the previous summer, and there, on Ron's shoulder, was Scabbers.

"How did you get this?" Lupin asked Black, thunderstruck.

"Fudge," said Black. "When he came to inspect Azkaban last year, he gave me his paper. And there was Peter, on the front page on this boy's shoulder...I knew him at once...how many times had I seen him transform? And the caption said the boy would be going back to Hogwarts...to where Harry was..."

"My God," said Lupin softly, staring from Scabbers to the picture in the paper and back again. "His front paw..."

"What about it?" said Ron defiantly.

"He's got a toe missing," said Black.

"Of course," Lupin breathed. "So simple...so brilliant...he cut it off himself?"

"Just before he transformed," said Black. "When I cornered him, he yelled for the whole street to hear that I'd betrayed Lily and James. Then, before I could curse him, he blew apart the street with the wand behind his back, killed everyone within twenty feet of himself - and sped down into the sewer with the other rats..."

"Didn't you ever hear, Ron?" said Lupin. "The biggest bit of Peter they found was his finger."

"Look, Scabbers probably had a fight with another rat or something! He's been in my family for ages, right -"

"Twelve years, in fact," said Lupin. "Didn't you ever wonder why he was living so long?"

"We - we've been taking good care of him!" said Ron.

"Not looking too good at the moment, though, is he?" said Lupin. "I'd guess he's been losing weight ever since he heard Sirius was on the loose again..."

"He's been scared of that mad cat!" said Ron, nodding toward Crookshanks, who was still purring on the bed.

But that wasn't right, Harry thought suddenly...Scabbers had been looking ill before he met Crookshanks... ever since Ron's return from Egypt...since the time when Black had escaped...

"This cat isn't mad," said Black hoarsely. He reached out a bony hand and stroked Crookshanks's fluffy head. "He's the most intelligent of his kind I've ever met. He recognized Peter for what he was right away. And when he met me, he knew I was no dog. It was a while before he trusted me...Finally, I managed to communicate to him what I was after, and he's been helping me..."

"What do you mean?" breathed Hermione.

"He tried to bring Peter to me, but couldn't...so he stole the passwords into Gryffindor Tower for me...As I understand it, he took them from a boy's bedside table..."

Harry's brain seemed to be sagging under the weight of what he was hearing. It was absurd...and yet...

"But Peter got wind of what was going on and ran for it." croaked Black. "This cat - Crookshanks, did you call him? - told me Peter had left blood on the sheets...I supposed he bit himself...Well, faking his own death had worked once."

These words jolted Harry to his senses.

"And why did he fake his death?" he said furiously. "Because he knew you were about to kill him like you killed my parents!"

"No," said Lupin, "Harry-"

"And now you've come to finish him off!"

"Yes, I have," said Black, with an evil look at Scabbers.

"Then I should've let Snape take you!" Harry shouted.

"Harry," said Lupin hurriedly, "don't you see? All this time we've thought Sirius betrayed your parents, and Peter tracked him down - but it was the other way around, don't you see? Peter betrayed your mother and father - Sirius tracked Peter down -"

"THAT'S NOT TRUE!" Harry yelled. "HE WAS THEIR SECRET-KEEPER! HE SAID SO BEFORE YOU TURNED UP. HE SAID HE KILLED THEM!"

He was pointing at Black, who shook his head slowly; the sunken eyes were suddenly over bright.

"Harry...I as good as killed them," he croaked. "I persuaded Lily and James to change to Peter at the last moment, persuaded them to use him as Secret-Keeper instead of me...I'm to blame, I know it...The night they died, I'd arranged to check on Peter, make sure he was still safe, but when I arrived at his hiding place, he'd gone. Yet there was no sign of a struggle. It didn't feel right. I was scared. I set out for your parents' house straight away. And when I saw their house, destroyed, and their bodies...I realized what Peter must've done...what I'd done..."

His voice broke. He turned away.

"Enough of this," said Lupin, and there was a steely note in his voice Harry had never heard before. "There's one certain way to prove what really happened. Ron, give me that rat."

"What are you going to do with him if I give him to you?" Ron asked Lupin tensely.

"Force him to show himself," said Lupin. "If he really is a rat, it won't hurt him."

Ron hesitated. Then at long last, he held out Scabbers and Lupin took him. Scabbers began to squeak without stopping, twisting and turning, his tiny black eyes bulging in his head. "Ready, Sirius?" said Lupin.

Black had already retrieved Snape's wand from the bed. He approached Lupin and the struggling rat, and his wet eyes suddenly seemed to be burning in his face.

"Together?" he said quietly.

"I think so", said Lupin, holding Scabbers tightly in one hand and his wand in the other. "On the count of three. One - two - THREE!"

A flash of blue-white light erupted from both wands; for a moment, Scabbers was frozen in midair, his small gray form twisting madly - Ron yelled - the rat fell and hit the floor. There was another blinding flash of light and then -

It was like watching a speeded-up film of a growing tree. A head was shooting upward from the ground; limbs were sprouting; a moment later, a man was standing where Scabbers had been, cringing and wringing his hands. Crookshanks was spitting and snarling on the bed; the hair on his back was standing up.

He was a very short man, hardly taller than Harry and Hermione. His thin, colorless hair was unkempt and there was a large bald patch on top. He had the shrunken appearance of a plump man who has lost a lot of weight in a short time. His skin looked grubby, almost like Scabbers's fur, and something of the rat lingered around his pointed nose and his very small, watery eyes. He looked around at them all, his breathing fast and shallow. Harry saw his eyes dart to the door and back again.

"Well, hello, Peter," said Lupin pleasantly, as though rats frequently erupted into old school friends around him. "Long time, no see."

"S-Sirius...R-Remus..." Even Pettigrew's voice was squeaky. Again, his eyes darted toward the door. "My friends...my old friends..."

Black's wand arm rose, but Lupin seized him around the wrist, gave him a warning took, then turned again to Pettigrew, his voice light and casual.

"We've been having a little chat, Peter, about what happened the night Lily and James died. You might have missed the finer points while you were squeaking around down there on the bed -"

"Remus," gasped Pettigrew, and Harry could see beads of sweat breaking out over his pasty face, "you don't believe him, do you...? He tried to kill me, Remus..."

"So we've heard," said Lupin, more coldly. "I'd like to clear up one or two little matters with you, Peter, if you'll be so -"

"He's come to try and kill me again!" Pettigrew squeaked suddenly, pointing at Black, and Harry saw that he used his middle finger, because his index was missing. "He killed Lily and James and now he's going to kill me too...You've got to help me, Remus..."

Black's face looked more skull-like than ever as he stared at Pettigrew with his fathomless eyes.

"No one's going to try and kill you until we've sorted a few things out," said Lupin.

"Sorted things out?" squealed Pettigrew, looking wildly about him once more, eyes taking in the boarded windows and, again, the only door. "I knew he'd come after me! I knew he'd be back for me! I've been waiting for this for twelve years!"

"You knew Sirius was going to break out of Azkaban?" said Lupin, his brow furrowed. "When nobody has ever done it before?"

"He's got dark powers the rest of us can only dream of!" Pettigrew shouted shrilly. "How else did he get out of there? I suppose He-Who-Must-Not-Be-Named taught him a few tricks!"

Black started to laugh, a horrible, mirthless laugh that filled the whole room.

"Voldemort, teach me tricks?" he said.

Pettigrew flinched as though Black had brandished a whip at him.

"What, scared to hear your old master's name?" said Black. "I don't blame you, Peter. His lot aren't very happy with you, are they?"

"Don't know what you mean, Sirius -" muttered Pettigrew, his breathing faster than ever. His whole face was shining with sweat now.

"You haven't been hiding from me for twelve years," said Black. "You've been hiding from Voldemort's old supporters. I heard things in Azkaban, Peter...They all think you're dead, or you'd have to answer to them...I've heard them screaming all sorts of things in their sleep. Sounds like they think the double-crosser double-crossed them. Voldemort went to the Potters' on your information...and Voldemort met his downfall there. And not all Voldemort's supporters ended up in Azkaban, did they? There are still plenty out here, biding their time, pretending they've seen the error of their ways. If they ever got wind that you were still alive, Peter -"

"Don't know...what you're talking about..." said Pettigrew again, more shrilly than ever. He wiped his face on his sleeve and looked up at Lupin. "You don't believe this - this madness, Remus -"

"I must admit, Peter, I have difficulty in understanding why an innocent man would want to spend twelve years as a rat," said Lupin evenly.

"Innocent, but scared!" squealed Pettigrew. "If Voldemort's supporters were after me, it was because I put one of their best men in Azkaban - the spy, Sirius Black!"

Black's face contorted.

"How dare you," he growled, sounding suddenly like the bearsized dog he had been. "I, a spy for Voldemort? When did I ever sneak around people who were stronger and more powerful than myself? But you, Peter - I'll never understand why I didn't see you were the spy from the start. You always liked big friends who'd look after you, didn't you? It used to be us...me and Remus...and James..."

Pettigrew wiped his face again; he was almost panting for breath.

"Me, a spy...must be out of your mind...never...don't know how you can say such a -"

"Lily and James only made you Secret-Keeper because I suggested it," Black hissed, so venomously that Pettigrew took a step backward. "I thought it was the perfect plan...a bluff...Voldemort would be sure to come after me, would never dream they'd use a weak, talentless thing like you...It must have been the finest moment of your miserable life, telling Voldemort you could hand him the Potters."

Pettigrew was muttering distractedly; Harry caught words like "far-fetched" and "lunacy," but he couldn't help paying more attention to the ashen color of Pettigrew's face and the way his eyes continued to dart toward the windows and door.

"Professor Lupin?" said Hermione timidly. "Can - can I say something?"

"Certainly, Hermione," said Lupin courteously.

"Well - Scabbers - I mean, this - this man - he's been sleeping in Harry's dormitory for three years. If he's working for You-Know-Who, how come he never tried to hurt Harry before now?"

"There!" said Pettigrew shrilly, pointing at Ron with his maimed hand. "Thank you! You see, Remus? I have never hurt a hair of Harry's head! Why should I?"

"I'll tell you why," said Black. "Because you never did anything for anyone unless you could see what was in it for you. Voldemort's been in hiding for fifteen years, they say he's half dead. You weren't about to commit murder right under Albus Dumbledore's nose, for a wreck of a wizard who'd lost all of his power, were you? You'd want to be quite sure he was the biggest bully in the playground before you went back to him, wouldn't you? Why else did you find a wizard family to take you in? Keeping an ear out for news, weren't you, Peter? Just in case your old protector regained strength, and it was safe to rejoin him..."

Pettigrew opened his mouth and closed it several times. He seemed to have lost the ability to talk.

"Er - Mr. Black - Sirius?" said Hermione.

Black jumped at being addressed like this and stared at Hermione as though he had never seen anything quite like her.

"If you don't mind me asking, how - how did you get out of Azkaban, if you didn't use Dark Magic?"

"Thank you!" gasped Pettigrew, nodding frantically at her. "Exactly! Precisely what I -"

But Lupin silenced him with a look. Black was frowning slightly at Hermione, but not as though he were annoyed with her. He seemed to be pondering his answer.

"I don't know how I did it," he said slowly. "I think the only reason I never lost my mind is that I knew I was innocent. That wasn't a happy thought, so the Dementors couldn't suck it out of me...but it kept me sane and knowing who I am...helped me keep my powers...so when it all became...too much...I could transform in my cell...become a dog. Dementors can't see, you know..." He swallowed. "They feel their way toward people by feeding off their emotions...They could tell that my feelings were less - less human, less complex when I was a dog...but they thought, of course, that I was losing my mind like everyone else in there, so it didn't trouble them. But I was weak, very weak, and I had no hope of driving them away from me without a wand..."

"But then I saw Peter in that picture...I realized he was at Hogwarts with Harry...perfectly positioned to act, if one hint reached his ears that the Dark Side was gathering strength again..."

Pettigrew was shaking his head, mouthing noiselessly, but staring all the while at Black as though hypnotized.

"...ready to strike at the moment he could be sure of allies...and to deliver the last Potter to them. If he gave them Harry, who'd dare say he'd betrayed Lord Voldemort? He'd be welcomed back with honors..."

"So you see, I had to do something. I was the only one who knew Peter was still alive..."

Harry remembered what Mr. Weasley had told Mrs. Wealsey. 'The guards say he's been talking in his sleep... always the same words... 'He's at Hogwarts.''

"It was as if someone had lit a fire in my head, and the Dementors couldn't destroy it...It wasn't a happy feeling...it was an obsession...but it gave me strength, it cleared my mind. So, one night when they opened my door to bring food, I slipped past them as a dog...It's so much harder for them to sense animal emotions that they were confused...I was thin, very thin...thin enough to slip through the bars...I swam as a dog back to the mainland ...I journeyed north and slipped into the Hogwarts grounds as a dog. I've been living in the forest ever since, except when I came to watch the Quidditch, of course. You fly as well as your father did, Harry..."

He looked at Harry, who did not look away.

"Believe me," croaked Black. "Believe me, Harry. I never betrayed James and Lily. I would have died before I betrayed them."

And at long last, Harry believed him. Throat too tight to speak, he nodded.

"No!"

Pettigrew had fallen to his knees as though Harry's nod had been his own death sentence. He shuffled forward on his knees, groveling, his hands clasped in front of him as though praying.

"Sirius - it's me...it's Peter...your friend...you wouldn't -"

Black kicked out and Pettigrew recoiled.

"There's enough filth on my robes without you touching them," said Black.

"Remus!" Pettigrew squeaked, turning to Lupin instead, writhing imploringly in front of him. "You don't believe this - wouldn't Sirius have told you they'd changed the plan?"

"Not if he thought I was the spy, Peter," said Lupin. "I assume that's why you didn't tell me, Sirius?" he said casually over Pettigrew's head.

"Forgive me, Remus," said Black.

"Not at all, Padfoot, old friend," said Lupin, who was now rolling up his sleeves. "And will you, in turn, forgive me for believing you were the spy?"

"Of course," said Black, and the ghost of a grin flitted across his gaunt face. He, too, began rolling up his sleeves. "Shall we kill him together?"

"Yes, I think so," said Lupin grimly.

"You wouldn't...you won't..." gasped Pettigrew. And he scrambled around to Ron.

"Ron...haven't I been a good friend...a good pet? You won't let them kill me, Ron, will you...you're on my side, aren't you?"

But Ron was staring at Pettigrew with the utmost revulsion.

"I let you sleep in my bed!" he said.

"Kind boy...kind master..." Pettigrew crawled toward Ron "You won't let them do it...I was your rat...I was a good pet..."

"If you made a better rat than a human, it's not much to boast about, Peter," said Black harshly. Ron, going still paler with pain, wrenched his broken leg out of Pettigrew's reach. Pettigrew turned on his knees, staggered forward, and seized the hem of Hermione's robes.

"Sweet girl...clever girl...you - you won't let them...Help me..."

Hermione pulled her robes out of Pettigrew's clutching hands and backed away against the wall, looking horrified.

Pettigrew knelt, trembling uncontrollably, and turned his head slowly toward Harry.

"Harry...Harry...you look just like your father...just like him..."

"HOW DARE YOU SPEAK TO HARRY?" roared Black. "HOW DARE YOU FACE HIM? HOW DARE YOU TALK ABOUT JAMES IN FRONT OF HIM?"

"Harry," whispered Pettigrew, shuffling toward him, hands outstretched. "Harry, James wouldn't have wanted me killed...James would have understood, Harry...he would have shown me mercy..."

Both Black and Lupin strode forward, seized Pettigrew's shoulders, and threw him backward onto the floor. He sat there, twitching with terror, staring up at them.

"You sold Lily and James to Voldemort," said Black, who was shaking too. "Do you deny it?"

Pettigrew burst into tears. It was horrible to watch, like an oversized, balding baby, cowering on the floor.

"Sirius, Sirius, what could I have done? The Dark Lord...you have no idea...he has weapons you can't imagine ...I was scared, Sirius, I was never brave like you and Remus and James. I never meant it to happen...He-Who-Must-Not-Be-Named forced me -"

"DON'T LIE!" bellowed Black. "YOU'D BEEN PASSING INFORMATION TO HIM FOR A YEAR BEFORE LILY AND JAMES DIED! YOU WERE HIS SPY!"

"He - he was taking over everywhere!" gasped Pettigrew. "Wh-what was there to be gained by refusing him?"

"What was there to be gained by fighting the most evil wizard who has ever existed?" said Black, with a terrible fury in his face. "Only innocent lives, Peter!"

"You don't understand!" whined Pettigrew. "He would have killed me, Sirius!"

"THEN YOU SHOULD HAVE DIED!" roared Black. "DIED RATHER THAN BETRAY YOUR FRIENDS, AS WE WOULD HAVE DONE FOR YOU!"

Black and Lupin stood shoulder to shoulder, wands raised.

"You should have realized," said Lupin quietly, "if Voldemort didn't kill you, we would. Good-bye, Peter."

Hermione covered her face with her hands and turned to the wall.

"NO!" Harry yelled. He ran forward, placing himself in front Pettigrew, facing the wands. "You can't kill him," he said breathlessly. "You can't."

Black and Lupin both looked staggered.

"Harry, this piece of vermin is the reason you have no parents," Black snarled. "This cringing bit of filth would have seen you die too, without turning a hair. You heard him. His own stinking skin meant more to him than your whole family."

"I know," Harry panted. "We'll take him up to the castle. We'll hand him over to the Dementors...He can go to Azkaban...but don't kill him."

"Harry!" gasped Pettigrew, and he flung his arms around Harry's knees. "You - thank you - it's more than I deserve - thank you -"

"Get off me," Harry spat, throwing Pettigrew's hands off him in disgust. "I'm not doing this for you. I'm doing it because - I don't reckon my dad would've wanted them to become killers - just for you."

No one moved or made a sound except Pettigrew, whose breath was coming in wheezes as he clutched his chest. Black and Lupin were looking at each other. Then, with one movement, they lowered their wands.

"You're the only person who has the right to decide, Harry," said Black. "But think... think what he did..."

"He can go to Azkaban," Harry repeated. "If anyone deserves that place, he does..."

Pettigrew was still wheezing behind him.

"Very well," said Lupin. "Stand aside, Harry."

Harry hesitated.

"I'm going to tie him up," said Lupin. "That's all, I swear."

Harry stepped out of the way. Thin cords shot from Lupin's wand this time, and next moment, Pettigrew was wriggling on the floor, bound and gagged.

"But if you transform, Peter," growled Black, his own wand pointing at Pettigrew too, "we will kill you. You agree, Harry?"

Harry looked down at the pitiful figure on the floor and nodded so that Pettigrew could see him.

"Right," said Lupin, suddenly businesslike. "Ron, I can't mend bones nearly as well as Madam Pomfrey, so I think it's best if we just strap your leg up until we can get you to the hospital wing."

He hurried over to Ron, bent down, tapped Ron's leg with his wand, and muttered, "Ferula." Bandages spun up Ron's leg, strapping it tightly to a splint. Lupin helped him to his feet; Ron put his weight gingerly on the leg and didn't wince.

"That's better," he said. "Thanks."

"What about Professor Snape?" said Hermione in a small voice, looking down at Snape's prone figure.

"There's nothing seriously wrong with him," said Lupin, bending over Snape and checking his pulse. "You were just a little - overenthusiastic. Still out cold. Er - perhaps it will be best if we don't revive him until we're safety back in the castle. We can take him like this..."

He muttered, "Mobilicorpus." As though invisible strings were tied to Snape's wrists, neck, and knees, he was pulled into a standing position, head still lolling unpleasantly, like a grotesque puppet. He hung a few inches above the ground, his limp feet dangling. Hermione picked up the Invisibility Cloak and tucked it safely into her pocket.

"And two of us should be chained to this," said Black, nudging Pettigrew with his toe. "Just to make sure."

"I'll do it," said Lupin.

"And me," said Ron savagely, limping forward.

Black conjured heavy manacles from thin air; soon Pettigrew was upright again, left arm chained to Lupin's right, right arm to Ron's left. Ron's face was set. He seemed to have taken Scabbers's true identity as a personal insult. Crookshanks leapt lightly off the bed and led the way out of the room, his bottlebrush tail held jauntily high.

Chapter 20

Harry had never been part of a stranger group. Crookshanks led the way down the stairs; Lupin, Pettigrew, and Ron went next, looking like entrants in a six-legged race. Next came Professor Snape, drifting creepily along, his toes hitting each stair as they descended, held up by his own wand, which was being pointed at him by Sirius. Harry and Hermione brought up the rear.

Getting back into the tunnel was difficult. Lupin, Pettigrew, and Ron had to turn sideways to manage it; Lupin still had Pettigrew covered with his wand. Harry could see them edging awkwardly along the tunnel in single file. Crookshanks was still in the lead. Harry went right after Black, who was still making Snape drift along ahead of them; he kept bumping his lolling head on the low ceiling. Harry had the impression Black was making no effort to prevent this.

"You know what this means?" Black said abruptly to Harry as they made their slow progress along the tunnel. "Turning Pettigrew in?"

"You're free," said Harry.

"Yes..." said Black. "But I'm also - I don't know if anyone ever told you - I'm your godfather."

"Yeah, I knew that," said Harry.

"Well... your parents appointed me your guardian," said Black stiffly. "If anything happened to them..."

Harry waited. Did Black mean what he thought he meant?

"I'll understand, of course, if you want to stay with your aunt and uncle," said Black. "But... well... think about it. Once my name's cleared... if you wanted a... a different home..."

Some sort of explosion took place in the pit of Harry's stomach.

"What - live with you?" he said, accidentally cracking his head on a bit of rock protruding from the ceiling. "Leave the Dursleys?"

"Of course, I thought you wouldn't want to," said Black quickly. "I understand, I just thought I'd -"

"Are you insane?" said Harry, his voice easily as croaky as Black's. "Of course I want to leave the Dursleys! Have you got a house? When can I move in?"

Black turned right around to look at him; Snape's head was scraping the ceiling but Black didn't seem to care.

"You want to?" he said. "You mean it?"

"Yeah, I mean it!" said Harry.

Black's gaunt face broke into the first true smile Harry had seen upon it. The difference it made was startling, as though a person ten years younger were shining through the starved mask; for a moment, he was recognizable as the man who had laughed at Harry's parents' wedding.

They did not speak again until they had reached the end of the tunnel. Crookshanks darted up first; he had evidently pressed his paw to the knot on the trunk, because Lupin, Pettigrew, and Ron clambered upward without any sound of savaging branches.

Black saw Snape up through the hole, then stood back for Harry and Hermione to pass. At last, all of them were out.

The grounds were very dark now; the only light came from the distant windows of the castle. Without a word, they set off. Pettigrew was still wheezing and occasionally whimpering. Harry's mind was buzzing. He was going to leave the Dursleys. He was going to live with Sirius Black, his parents' best friend... He felt dazed... What would happen when he told the Dursleys he was going to live with the convict they'd seen on television...!

"One wrong move, Peter," said Lupin threateningly ahead. His wand was still pointed sideways at Pettigrew's chest.

Silently they tramped through the grounds, the castle lights growing slowly larger. Snape was still drifting weirdly ahead of Black, his chin bumping on his chest. And then -

A cloud shifted. There were suddenly dim shadows on the ground. Their party was bathed in moonlight.

Snape collided with Lupin, Pettigrew, and Ron, who had stopped abruptly. Black froze. He flung out one arm to make Harry and Hermione stop.

Harry could see Lupin's silhouette. He had gone rigid. Then his limbs began to shake.

"Oh, my -" Hermione gasped. "He didn't take his potion tonight! He's not safe!"

"Run," Black whispered. "Run. Now."

But Harry couldn't run. Ron was chained to Pettigrew and Lupin. He leapt forward but Black caught him around the chest and threw him back.

"Leave it to me - RUN!"

There was a terrible snarling noise. Lupin's head was lengthening. So was his body. His shoulders were hunching. Hair was sprouting visibly on his face and hands, which were curling into clawed paws. Crookshanks's hair was on end again; he was backing away -

As the werewolf reared, snapping its long jaws, Sirius disappeared from Harry's side. He had transformed. The enormous, bearlike dog bounded forward. As the werewolf wrenched itself free of the manacle binding it, the dog seized it about the neck and pulled it backward, away from Ron and Pettigrew. They were locked, jaw to jaw, claws ripping at each other.

Harry stood, transfixed by the sight, too intent upon the battle to notice anything else. It was Hermione's scream that alerted him -

Pettigrew had dived for Lupin's dropped wand. Ron, unsteady on his bandaged leg, fell. There was a bang, a burst of light - and Ron lay motionless on the ground. Another bang - Crookshanks flew into the air and back to the earth in a heap.

"Expelliarmus." Harry yelled, pointing his own wand at Pettigrew; Lupin's wand flew high into the air and out of sight. "Stay where you are!" Harry shouted, running forward.

Too late. Pettigrew had transformed. Harry saw his bald tail whip through the manacle on Ron's outstretched arm and heard a scurrying through the grass.

There was a howl and a rumbling growl; Harry turned to see the werewolf taking flight; it was galloping into the forest -

"Sirius, he's gone, Pettigrew transformed!" Harry yelled.

Black was bleeding; there were gashes across his muzzle and back, but at Harry's words he scrambled up again, and in an instant, the sound of his paws faded to silence as he pounded away across the grounds.

Harry and Hermione dashed over to Ron.

"What did he do to him?" Hermione whispered. Ron's eyes were only half-closed, his mouth hung open; he was definitely alive, they could hear him breathing, but he didn't seem to recognize them.

"I don't know..."

Harry looked desperately around. Black and Lupin both gone... they had no one but Snape for company, still hanging, unconscious, in midair.

"We'd better get them up to the castle and tell someone," said Harry, pushing his hair out of his eyes, trying to think straight. "Come -"

But then, from beyond the range of their vision, they heard a yelping, a whining: a dog in pain...

"Sirius," Harry muttered, staring into the darkness.

He had a moment's indecision, but there was nothing they could do for Ron at the moment, and by the sound of it, Black was in trouble -

Harry set off at a run, Hermione right behind him. The yelping seemed to be coming from the ground near the edge of the lake. They pelted toward it, and Harry, running flat out, felt the cold and suddenly realized what it must mean. He stopped abruptly and put his hand out in front of Hermione to stop her too.

"What?!" she shrieked.

"Dementors," said Harry. "I can feel it."

"But they'll give him the kiss!"

"I know how to drive them away," said Harry, "but I can't get too close to them. Wait here," he said. Instead of running to the bank where the yelping was coming from, he ran to the opposite bank.

And then Harry saw them. Dementors, at least a hundred of them, gliding in a black mass around the lake toward a shadowy figure. They were going to give Sirius the kiss. Harry thought about living with Sirius, and mustering all his concentration, he raised his wand and pointed it at the Dementors.

"EXPECTO PATRONUM! " he yelled.

And out of the end of his wand burst a blinding, dazzling, silver animal. He screwed up his eyes, trying to see what it was. It looked like a horse. It was galloping silently away from him, across the black surface of the lake. He saw it lower its head and charge at the swarming Dementors... Now it was galloping around and around the black shapes on the ground, and the Dementors were falling back, scattering, retreating into the darkness... They were gone.

The Patronus turned. It was cantering back toward Harry across the still surface of the water. It wasn't a horse. It wasn't a unicorn, either. It was a stag. It was shining brightly as the moon above ... it was coming back to him...

It stopped on the bank. Its hooves made no mark on the soft ground as it stared at Harry with its large, silver eyes. Slowly, it bowed its antlered head. And Harry realized... "Prongs," he whispered.

But as his trembling fingertips stretched toward the creature, it vanished.

Chapter 21

Harry stood there, hand still outstretched. Then, with a great leap of his heart, he heard hooves behind him. He whirled around and saw Hermione dashing toward him, dragging Buckbeak behind her. He hadn't given Buckbeak a single thought since Ron had been dragged under the Whomping Willow.

"I just untied Buckbeak," she said. "What did you do?"

"I just saved Sirius."

"Harry, I can't believe it... You conjured up a Patronus that drove away all those Dementors! That's very, very advanced magic."

"Thanks," said Harry. "What are we going to do now? Pettigrew has escaped, which means Sirius will have to escape as well."

"Right," said Hermione, "which is why I brought Buckbeak over here. Sirius and Buckbeak can escape together."

"That's a great idea!" said Harry, "let's hurry and-"

"Harry, look at Snape!"

Together they peered around the bush at the other bank. Snape had regained consciousness. He conjured a stretcher and lifted the limp form of Black onto it. A second stretcher, no doubt bearing Ron, was already floating at his side. Then, wand held out in front of him, he moved them away toward the castle. Harry's heart sank like a stone. They were too late.

"Hermione, we've got to tell Dumbledore. He might believe us."

"We can't count on that," said Hermione, taking out the invisibility cloak. "Listen, you wait here with Buckbeak, and I'll follow Snape and find out what's happening to Sirius. Maybe we can still rescue him." And with that, she threw the cloak over herself, and Harry heard her sprinting towards the small figures of Snape, Ron, and Sirius.

Harry hoped Hermione was right. He couldn't bear the thought of his godfather getting the kiss. All the events that had happened so far tonight chased each other around in Harry's mind until he finally heard Hermione running back towards him. She threw off the cloak, beaming.

"They've locked Sirius in Professor Flitwick's office on the seventh floor. They're sending Macnair to get the Dementors." She jerked her thumb behind her.

Harry stared through the darkness. A man was hurrying across the grounds, toward one of the entrances. Something shiny glinted in his belt.

"Macnair!" said Harry. "The executioner! He's gone to get the Dementors! This is it, Hermione -"

Hermione put her hands on Buckbeak's back and Harry gave her a leg up. Then he placed his foot on one of the lower branches of the bush and climbed up in front of her. He pulled Buckbeak's rope back over his neck and tied it to the other side of his collar like reins.

"Ready?" he whispered to Hermione. "You'd better hold on to me -"

He nudged Buckbeak's sides with his heels.

Buckbeak soared straight into the dark air. Harry gripped his flanks with his knees, feeling the great wings rising powerfully beneath them. Hermione was holding Harry very tight around the waist; he could hear her muttering, "Oh, no - I don't like this oh, I really don't like this -"

Harry urged Buckbeak forward. They were gliding quietly toward the upper floors of the castle... Harry pulled hard on the left-hand side of the rope, and Buckbeak turned. Harry was trying to count the windows flashing past -

"Whoa!" he said, pulling backward as hard as he could.

Buckbeak slowed down and they found themselves at a stop, unless you counted the fact that they kept rising up and down several feet as the Hippogriff beat his wings to remain airborne.

"He's there!" Harry said, spotting Sirius as they rose up beside the window. He reached out, and as Buckbeak's wings fell, was able to tap sharply on the glass.

Black looked up. Harry saw his jaw drop. He leapt from his chair, hurried to the window and tried to open it, but it was locked.

"Stand back!" Hermione called to him, and she took out her wand, still gripping the back of Harry's robes with her left hand.

"Alohomora!"

The window sprang open.

"How - how -?" said Black weakly, staring at the Hippogriff.

"Get on - there's not much time," said Harry, gripping Buckbeak firmly on either side of his sleek neck to hold him steady. "You've got to get out of here -the Dementors are coming - Macnair's gone to get them."

Black placed a hand on either side of the window frame and heaved his head and shoulders out of it. It was very lucky he was so thin. In seconds, he had managed to fling one leg over Buckbeak's back and pull himself onto the Hippogriff behind Hermione.

"Okay, Buckbeak, up!" said Harry, shaking the rope. "Up to the tower - come on."

The Hippogriff gave one sweep of its mighty wings and they were soaring upward again, high as the top of the West Tower. Buckbeak landed with a clatter on the battlements, and Harry and Hermione slid off him at once.

"Sirius, you'd better go, quick," Harry panted. "They'll reach Flitwick's office any moment, they'll find out you're gone."

Buckbeak pawed the ground, tossing his sharp head.

"What happened to the other boy? Ron?" croaked Sirius.

"I think he's going to be okay," said Harry. "Snape took him back up to the castle. Quick. Go."

But Black was still staring down at Harry.

"How can I ever thank -"

"GO!" Harry and Hermione shouted together.

Black wheeled Buckbeak around, facing the open sky.

"We'll see each other again," he said. "You are - truly your father's son, Harry..."

He squeezed Buckbeak's sides with his heels. Harry and Hermione jumped back as the enormous wings rose once more... The Hippogriff took off into the air... He and his rider became smaller and smaller as Harry gazed after them... then a cloud drifted across the moon... They were gone.

Chapter 22

"Harry!"

Hermione was tugging at his sleeve.

"I've got an idea. We've got to go back under the Whomping Willow. We can make it look like Sirius trapped us in the Shrieking Shack.

"No," said Harry firmly. "We need to check up on Ron. We can just as easily tell Madam Pomfrey that we came to the Hospital Wing from the Shrieking Shack. She knows he's our best friend. She'll understand."

"Oh all right," said Hermione. They flung the invisibility cloak over themselves and then slipped through the doorway behind them and down a tightly spiraling stone staircase. As they reached the bottom of it, they heard voices. They stopped walking and listened. It sounded like Fudge and Snape. They were walking quickly along the corridor at the foot of the staircase.

"... only hope Dumbledore's not going to make difficulties," Snape was saying. "The Kiss will be performed immediately?"

"As soon as Macnair returns with the Dementors. And then we'll have to search for Harry and the girl. I hope they're as fortunate as the Weasley boy. This whole Black affair has been highly embarrassing. I can't tell you how much I'm looking forward to informing the Daily Prophet that we've got him at last... I daresay they'll want to interview you, Snape... "

Harry caught a glimpse of Snape's smirk as he and Fudge passed Harry and Hermione. Their footsteps died away. Harry and Hermione waited a few moments to make sure they'd really gone, then started to walk in the opposite direction. Down one staircase, then another, along a new corridor - then they heard a cackling ahead.

"Peeves!" Harry muttered, grabbing Hermione's wrist. They came to a halt. Peeves was bouncing along the corridor in boisterous good spirits, laughing his head off. They waited until Peeves's gloating voice had faded into the distance, then continued walking.

They reached the end of the corridor with the hospital wing entrance.

The door opened. Dumbledore's back appeared.

"He's going to lock the door," Hermione whispered. Harry knew it would be no use hiding. They flung off the invisibility cloak.

Dumbledore backed out of the room, closed the door, and took out his wand to magically lock it. Panicking, Harry and Hermione ran forward. Dumbledore looked up. "We were wondering where you two where," said Dumbledore.

"How's Ron?" asked Harry.

"He will be just fine," said Dumbledore, "but you two have some explaining to do. Let's go inside."

Harry and Hermione followed Dumbledore inside the dormitory. It was empty except for Ron, who was lying motionless in the end bed.

"Well," said Dumbledore, "did you free him?"

They both looked at Dumbledore in horror.

"You have to listen to us," said Harry in a panic, "he's innocent, Peter Pettigrew-" but he saw to his surprise that Dumbledore was chuckling.

"I talked to Sirius right after he was captured, and he told me the full story. Then I realized why you two had disappeared."

"You mean you believe us?" asked Hermione timidly.

"Of course," said Dumbledore.

"Can you tell Fudge then?" asked Harry. "This way Sirius won't have to stay in hiding."

"Alas," began Dumbledore sadly, "I have no power to make other men see the truth. Sirius has not acted like an innocent man. The attack on the Fat Lady - entering Gryffindor Tower with a knife - without Pettigrew, alive or dead, we have no chance of clearing Sirius's name. Professor Snape told the minister that Sirius had confounded Mr. Weasley and yourselves, and I'm sorry to say that his version of events is far more convincing than yours."

"What about Professor Lupin?" asked Harry. "He knows the truth."

"Unfortunately," began Dumbledore, "werewolves are so mistrusted by most of our kind that his support will count for very little."

At that moment, they heard a distant roar of fury echoing from somewhere above them.

Madam Pomfrey came bustling out of her office.

"What was that?" she said in alarm.

Now they could hear angry voices, growing louder and louder. Harry made to grab his invisibility cloak, but Dumbledore grabbed him. "No," he said, as if reading his mind. "Lie down in one of the beds." Harry quickly got into one of the beds, while Hermione got into the bed on his right.

Madam Pomfrey was staring at the door. "Really - they'll wake everybody up! What do they think they're doing?"

Harry was trying to hear what the voices were saying. They were drawing nearer -

"He must have Disapparated, Severus. We should have left somebody in the room with him. When this gets out -"

"HE DIDN'T DISAPPARATE!" Snape roared, now very close at hand. "YOU CAN'T APPARATE OR DISAPPARATE INSIDE THIS CASTLE! THIS - HAS - SOMETHING - TO - DO - WITH - POTTER!"

BAM.

The door of the hospital wing burst open.

Fudge and Snape came striding into the ward. Fudge appeared angry. But Snape was beside himself.

"THERE THEY ARE! I TOLD YOU! OUT WITH IT, POTTER!" he bellowed. "WHAT DID YOU DO?"

"Professor Snape!" shrieked Madam Pomfrey. "Control yourself!"

"See here, Snape, be reasonable," said Fudge.

"THEY HELPED HIM ESCAPE, I KNOW IT!" Snape howled, pointing at Harry and Hermione. His face was twisted; spit was flying from his mouth. "Why else do you think they were gone!? If they didn't help him escape, where were they?"

"Well, that is a fair question," said Fudge.

Harry's heart sank. How on earth was he going to explain their absence? Hermione spoke up.

"Please sir, when Professor Lupin transformed, we were so frightened that we ran back under the Whomping Willow. We didn't come back out until we were positive that the danger had passed. And besides, how would we have even known were Sirius Black was located?"

"Well, there you have it," said Dumbledore beaming.

"See," said Fudge, "they didn't help him escape.

Snape stood there, seething, staring from Fudge, who looked thoroughly shocked at his behavior, to Dumbledore, whose eyes were twinkling behind his glasses. Snape whirled about, robes swishing behind him, and stormed out of the ward.

"Fellow seems quite unbalanced," said Fudge, staring after him. "I'd watch out for him if I were you, Dumbledore."

"Oh, he's not unbalanced," said Dumbledore quietly. "He's just suffered a severe disappointment."

"He's not the only one!" puffed Fudge. "The Daily Prophet's going to have a field day! We had Black cornered and he slipped through our fingers yet again! All it needs now is for the story of that Hippogriff's escape to get out, and I'll be a laughingstock! Well... I'd better go and notify the Ministry..."

"And the Dementors?" said Dumbledore. "They'll be removed from the school, I trust?"

"Oh yes, they'll have to go," said Fudge, running his fingers distractedly through his hair. "Never dreamed they'd attempt to administer the Kiss on an innocent boy... Completely out of control... no, I'll have them packed off back to Azkaban tonight ... Perhaps we should think about dragons at the school entrance..."

"Hagrid would like that," said Dumbledore, smiling at Harry and Hermione. As he and Fudge left the dormitory, Madam Pomfrey hurried to the door and locked it again. Muttering angrily to herself, she headed back to her office.

There was a low moan from the other end of the ward. Ron had woken up. They could see him sitting up, rubbing his head, looking around.

"What - what happened?" he groaned. "Harry? Why are we in here? Where's Sirius? Where's Lupin? What's going on?"

Harry and Hermione looked at each other.

"You explain," said Harry, helping himself to some more chocolate.

When Harry, Ron, and Hermione left the hospital wing at noon the next day, it was to find an almost deserted castle. The sweltering, heat and the end of the exams meant that everyone was taking full advantage of another Hogsmeade visit. Neither Ron nor Hermione felt like going, however, so they and Harry wandered onto the grounds, still talking about the extraordinary events of the previous night and wondering where Sirius and Buckbeak were now. Sitting near the lake, watching the giant squid waving its tentacles lazily above the water, Harry lost the thread of the conversation as he looked across to the opposite bank. The stag had galloped toward him from there just last night...

A shadow fell across them and they looked up to see a very bleary-eyed Hagrid, mopping his sweaty face with one of his tablecloth-sized handkerchiefs and beaming down at them.

"Know I shouldn' feel happy, after wha' happened las' night," he said. "I mean, Black escapin' again, an, everythin' - but guess what?"

"What?" they said, pretending to look curious.

"Beaky! He escaped! He's free! Bin celebratin' all night!"

"That's wonderful!" said Hermione, giving Ron a reproving look because he looked as though he was close to laughing.

"Yeah... can't've tied him up properly," said Hagrid, gazing happily out over the grounds. "I was worried this mornin', mind... thought he mighta met Professor Lupin on the grounds, but Lupin says he never ate anythin' las' night..."

"What?" said Harry quickly.

"Blimey, haven' yeh heard?" said Hagrid, his smile fading a little. He lowered his voice, even though there was nobody in sight. "Er - Snape told all the Slytherins this mornin'... Thought everyone'd know by now... Professor Lupin's a werewolf, see. An' he was loose on the grounds las' night... He's packin' now, o' course."

"He's packing?" said Harry, alarmed. "Why?"

"Leavin', isn' he?" said Hagrid, looking surprised that Harry had to ask. "Resigned firs' thing this mornin'. Says he can't risk it happenin again."

Harry scrambled to his feet.

"I'm going to see him," he said to Ron and Hermione.

"But if he's resigned -"

"¨C doesn't sound like there's anything we can do -"

"I don't care. I still want to see him. I'll meet you back here."

Lupin's office door was open. He had already packed most of his things. The Grindylow's empty tank stood next to his battered old suitcase, which was open and nearly full. Lupin was bending over something on his desk and looked up only when Harry knocked on the door.

"I saw you coming," said Lupin, smiling. He pointed to the parchment he had been poring over. It was the Marauder's Map.

"I just saw Hagrid," said Harry. "And he said you'd resigned. It's not true, is it?"

"I'm afraid it is," said Lupin. He started opening his desk drawers and taking out the contents.

"Why?" said Harry. "The Ministry of Magic don't think you were helping Sirius, do they?"

Lupin crossed to the door and closed it behind Harry.

"No. Professor Dumbledore managed to convince Fudge that I was trying to save your lives." He sighed. "That was the final straw for Severus. I think the loss of the Order of Merlin hit him hard. So he - er - accidentally let slip that I am a werewolf this morning at breakfast."

"You're not leaving just because of that!" said Harry.

Lupin smiled wryly.

"This time tomorrow, the owls will start arriving from parents... They will not want a werewolf teaching their children, Harry. And after last night, I see their point. I could have bitten any of you... That must never happen again."

"You're the best Defense Against the Dark Arts teacher we've ever had!" said Harry. "Don't go!"

Lupin shook his head and didn't speak. He carried on emptying his drawers. Then, while Harry was trying to think of a good argument to make him stay, Lupin said, "From what the headmaster told me this morning, you saved a lot of lives last night, Harry. If I'm proud of anything I've done this year, it's how much you've learned... Tell me about your Patronus."

"How d'you know about that?" said Harry, distracted.

"What else could have driven the Dementors back?"

Harry told Lupin what had happened. When he'd finished, Lupin was smiling again.

"Yes, your father was always a stag when he transformed," he said. "You guessed right... that's why we called him Prongs."

Lupin threw his last few books into his case, closed the desk drawers, and turned to look at Harry.

"Here - I brought this from the Shrieking Shack last night," he said, handing Harry back the Invisibility Cloak. "And..." He hesitated, then held out the Marauder's Map too. "I am no longer your teacher, so I don't feel guilty about giving you back this as well. It's no use to me, and I daresay you, Ron, and Hermione will find uses for it."

Harry took the map and grinned.

"You told me Moony, Wormtail, Padfoot, and Prongs would've wanted to lure me out of school... you said they'd have thought it was funny."

"And so we would have," said Lupin, now reaching down to close his case. "I have no hesitation in saying that James would have been highly disappointed if his son had never found any of the secret passages out of the castle."

There was a knock on the door. Harry hastily stuffed the Marauder's Map and the Invisibility Cloak into his pocket.

It was Professor Dumbledore. He didn't look surprised to see Harry there.

"Your carriage is at the gates, Remus," he said.

"Thank You, Headmaster."

Lupin picked up his old suitcase and the empty Grindylow tank.

"Well - good-bye, Harry," he said, smiling. "It has been a real pleasure teaching you. I feel sure we'll meet again sometime. Headmaster, there is no need to see me to the gates, I can manage..."

Harry had the impression that Lupin wanted to leave as quickly as possible.

"Good-bye, then, Remus," said Dumbledore soberly. Lupin shifted the Grindylow tank slightly so that he and Dumbledore could shake hands. Then, with a final nod to Harry and a swift smile, Lupin left the office.

Harry sat down in his vacated chair, staring glumly at the floor. He heard the door close and looked up. Dumbledore was still there.

"Why so miserable, Harry?" he said quietly. "You should be very proud of yourself after last night."

"It didn't make any difference," said Harry bitterly. "Pettigrew got away."

"Didn't make any difference?" said Dumbledore quietly, "It made all the difference in the world, Harry. You helped uncover the truth. You saved an innocent man from a terrible fate."

Terrible. Something stirred in Harry's memory. Greater and more terrible than ever before... Professor Trelawney's prediction!

"Professor Dumbledore - yesterday, when I was having my Divination exam, Professor Trelawney went very - very strange."

"Indeed?" said Dumbledore. "Er - stranger than usual, you mean?"

"Yes... her voice went all deep and her eyes rolled and she said ... she said Voldemort's servant was going to set out to return to him before midnight... She said the servant would help him come back to power." Harry stared up at Dumbledore. "And then she sort of became normal again, and she couldn't remember anything she'd said. Was it - was she making a real prediction?"

Dumbledore looked mildly impressed.

"Do you know, Harry, I think she might have been." he said thoughtfully. "Who'd have thought it? That brings her total of real predictions up to two. I should offer her a pay raise..."

"But -" Harry looked at him, aghast. How could Dumbledore take this so calmly?

"But - I stopped Sirius and Professor Lupin from killing Pettigrew! That makes it my fault if Voldemort comes back!"

"It does not," said Dumbledore quietly. "The consequences of our actions are always so complicated, so diverse, that predicting the future is a very difficult business indeed... Professor Trelawney, bless her, is living proof of that... You did a very noble thing, in saving Pettigrew's life."

"But if he helps Voldemort back to power..."

"Pettigrew owes his life to you. You have sent Voldemort a deputy who is in your debt... When one wizard saves another wizard's life, it creates a certain bond between them... and I'm much mistaken if Voldemort wants his servant in the debt of Harry Potter."

"I don't want a connection with Pettigrew!" said Harry. "He betrayed my parents!"

"This is magic at its deepest, its most impenetrable, Harry. But trust me... the time may come when you will be very glad you saved Pettigrew's life."

Harry couldn't imagine when that would be. Dumbledore looked as though he knew what Harry was thinking.

"I knew your father very well, both at Hogwarts and later, Harry," he said gently. "He would have saved Pettigrew too, I am sure of it."

Harry looked up at him. Dumbledore wouldn't laugh - he could tell Dumbledore...

"I thought it was my dad who'd conjured my Patronus. I mean, when I saw myself across the lake ... I thought I was seeing him."

"An easy mistake to make," said Dumbledore softly. "I expect you'll tire of hearing it, but you do look extraordinarily like James. Except for the eyes... you have your mother's eyes."

Harry shook his head.

"It was stupid, thinking it was him," he muttered. "I mean, I knew he was dead."

"You think the dead we loved ever truly leave us? You think that we don't recall them more clearly than ever in times of great trouble? Your father is alive in you, Harry, and shows himself most plainly when you have need of him. How else could you produce that particular Patronus? Prongs rode again last night."

It took a moment for Harry to realize what Dumblefore had said.

"Last night Sirius told me all about how they became Animagi," said Dumbledore, smiling. "An extraordinary achievement - not least, keeping it quiet from me. And then I remembered the most unusual form your Patronus took, when it charged Mr. Malfoy down at your Quidditch match against Ravenclaw. You know, Harry, in a way, you did see your father last night... You found him inside yourself."

And Dumbledore left the office, leaving Harry to his very confused thoughts.

Nobody at Hogwarts now knew the truth of what had happened the night that Sirius, Buckbeak, and Pettigrew had vanished except Harry, Ron, Hermione, and Professor Dumbledore. As the end of term approached, Harry heard many different theories about what had really happened, but none of them came close to the truth.

Malfoy was furious about Buckbeak. He was convinced that Hagrid had found a way of smuggling the Hippogriff to safety, and seemed outraged that he and his father had been outwitted by a gamekeeper. Percy Weasley, meanwhile, had much to say on the subject of Sirius's escape.

"If I manage to get into the Ministry, I'll have a lot of proposals to make about Magical Law Enforcement!" he told the only person who would listen - his girlfriend, Penelope.

Though the weather was perfect, though the atmosphere was so cheerful, though he knew they had achieved the near impossible in helping Sirius to freedom, Harry had never approached the end of a school year in worse spirits.

He certainly wasn't the only one who was sorry to see Professor Lupin go. The whole of Harry's Defense Against the Dark Arts class was miserable about his resignation.

"Wonder what they'll give us next year?" said Seamus Finnigan gloomily.

"Maybe a vampire," suggested Dean Thomas hopefully.

It wasn't only Professor Lupin's departure that was weighing on Harry's mind. He couldn't help thinking a lot about Professor Trelawney's prediction. He kept wondering where Pettigrew was now, whether he had sought sanctuary with Voldemort yet. But the thing that was lowering Harry's spirits most of all was the prospect of returning to the Dursleys. For maybe half an hour, a glorious half hour, he had believed he would be living with Sirius from now on...his parents' best friend...It would have been the next best thing to having his own father back. And while no news of Sirius was definitely good news, because it meant he had successfully gone into hiding, Harry couldn't help feeling miserable when he thought of the home he might have had, and the fact that it was now impossible.

The exam results came out on the last day of term. Harry, Ron, and Hermione had passed every subject. Harry was amazed that he had got through Potions. He had a shrewd suspicion that Dumbledore might have stepped in to stop Snape failing him on purpose. Snape's behavior toward Harry over the past week had been quite alarming. Harry wouldn't have thought it possible that Snape's dislike for him could increase, but it certainly had. A muscle twitched unpleasantly at the corner of Snape's thin mouth every time he looked at Harry, and he was constantly flexing his fingers, as though itching to place them around Harry's throat.

Percy had got his top-grade N.E.W.T.s; Fred and George had scraped a handful of O.W.L.s each. Gryffindor House, meanwhile, largely thanks to their spectacular performance in the Quidditch Cup, had won the House championship for the third year running. This meant that the end of term feast took place amid decorations of scarlet and gold, and that the Gryffindor table was the noisiest of the lot, as everybody celebrated. Even Harry managed to forget about the journey back to the Dursleys the next day as he ate, drank, talked, and laughed with the rest.

As the Hogwarts Express pulled out of the station the next morning Harry watched Hogwarts disappear from view behind a mountain. Two whole months before he'd see it again...

"Oh, cheer up, Harry!" said Hermione sadly.

"I'm okay," said Harry quickly. "Just thinking about the holidays."

"Yeah, I've been thinking about them too," said Ron. "Harry, you've got to come and stay with us. I'll fix it up with Mum and Dad, then I'll call you. I know how to use a fellytone now -"

"A telephone, Ron," said Hermione. "Honestly, you should take Muggle Studies next year..."

Ron ignored her.

"It's the Quidditch World Cup this summer! How about it, Harry? Come and stay, and we'll go and see it! Dad can usually get tickets from work."

This proposal had the effect of cheering Harry up a great deal.

"Yeah... I bet the Dursleys'd be pleased to let me come... especially after what I did to Aunt Marge..."

Feeling considerably more cheerful, Harry joined Ron and Hermione in several games of Exploding Snap, and when the witch with the tea cart arrived, he bought himself a very large lunch, though nothing with chocolate in it.

But it was late in the afternoon before the thing that made him truly happy turned up...

"Harry," said Hermione suddenly, peering over his shoulder. "What's that thing outside your window?"

Harry turned to look outside. Something very small and gray was bobbing in and out of sight beyond the glass. He stood up for a better look and saw that it was a tiny owl, carrying a letter that was much too big for it. The owl was so small, in fact, that it kept tumbling over in the air, buffeted this way and that in the train's slipstream. Harry quickly pulled down the window, stretched out his arm, and caught it. It felt like a very fluffy Snitch. He brought it carefully inside.

The owl dropped its letter onto Harry's seat and began zooming around their compartment, apparently very pleased with itself for accomplishing its task. Hedwig clicked her beak with a sort of dignified disapproval. Crookshanks sat up in his seat, following the owl with his great yellow eyes. Ron, noticing this, snatched the owl safely out of harm's way.

Harry picked up the letter. It was addressed to him. He ripped open the letter, and shouted, "It's from Sirius!"

"What?" said Ron and Hermione excitedly. "Read it aloud!"

Dear Harry,
I hope this finds you before you reach your aunt and uncle. I don't know whether they're used to owl post.
Buckbeak and I are in hiding. I won't tell you where, in case this owl falls into the wrong hands. I have some doubt about his reliability, but he is the best I could find, and he did seem eager for the job.
I believe the Dementors are still searching for me, but they haven't a hope of finding me here. I am planning to allow some Muggles to glimpse me soon, a long way from Hogwarts, so that the security on the castle will be lifted.
There is something I never got around to telling you during our brief meeting. It was I who sent you the Firebolt -
"Ha!" said Hermione triumphantly. "See! I told you it was from him!"

"Yes, but he hadn't jinxed it, had he?" said Ron. "Ouch!" The tiny owl now hooting happily in his hand, had nibbled one of his fingers in what it seemed to think was an affectionate way.

¨C Crookshanks took the order to the Owl Office for me. I used your name but told them to take the gold from my own Gringotts vault. Please consider it as thirteen birthdays' worth of presents from your godfather.
I would also like to apologize for the fright I think I gave you that night last year when you left your uncle's house. I had only hoped to get a glimpse of you before starting my journey north, but I think the sight of me alarmed you.
I am enclosing something else for you, which I think will make your next year at Hogwarts more enjoyable.
If ever you need me, send word. Your owl will find me.
I'll write again soon.
Sirius
Harry looked eagerly inside the envelope. There was another piece of parchment in there. He read it through quickly and felt suddenly as warm and contented as though he'd swallowed a bottle of hot butterbeer in one gulp.

I, Sirius Black, Harry Potter's godfather, hereby give him permission to visit Hogsmeade on weekends. "That'll be good enough for Dumbledore!" said Harry happily. He looked back at Sirius's letter. "Hang on, there's a PS..."
I thought your friend Ron might like to keep this owl, as it's my fault he no longer has a rat.
Ron's eyes widened. The minute owl was still hooting excitedly. "Keep him?" he said uncertainly. He looked closely at the owl for a moment; then, to Harry's and Hermione's great surprise, he held him out for Crookshanks to sniff.

"What do you reckon?" Ron asked the cat. "Definitely an owl?"

Crookshanks purred.

"That's good enough for me," said Ron happily. "He's mine."

Harry read and reread the letter from Sirius all the way back into King's Cross station. It was still clutched tightly in his hand as he, Ron, and Hermione stepped back through the barrier of platform nine and three-quarters. Harry spotted Uncle Vernon at once. He was standing a good distance from Mr. and Mrs. Weasley, eyeing them suspiciously, and when Mrs. Weasley hugged Harry in greeting, his worst suspicions about them seemed confirmed.

"I'll call about the World Cup!" Ron yelled after Harry as Harry bid him and Hermione good-bye, then wheeled the trolley bearing his trunk and Hedwig's cage toward Uncle Vernon, who greeted him in his usual fashion.

"What's that?" he snarled, staring at the envelope Harry was still clutching in his hand. "If it's another form for me to sign, you've got another -"

"It's not," said Harry cheerfully. "It's a letter from my godfather."

"Godfather?" sputtered Uncle Vernon. "You haven't got a godfather!"

"Yes, I have," said Harry brightly. "He was my mum and dad's best friend. He's a convicted murderer, but he's broken out of wizard prison and he's on the run. He likes to keep in touch with me, though ... keep up with my news ... check if I'm happy ..."

And, grinning broadly at the look of horror on Uncle Vernon's face, Harry set off toward the station exit, Hedwig rattling along in front of him, for what looked like a much better summer than the last.
