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

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

Snape was slightly breathless, and he seemed torn between triumph and abject fury.

"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've been helping your old friend into the castle Lupin, and here's the proof. I'd almost begun to believe that Amelia's opinion of you – but here you are!" he spat. "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 slowly, his eyes flashing with rage. "I shall be interested how Dumbledore takes this… he was quite convinced you were harmless, you know, Lupin… a tame werewolf…" he took a step forward. "And then there's Amelia… poor Amelia, wanting so much to believe you were honest, but you've let her down, Lupin."

Remus tensed, and began to growl, very quietly; behind him, Sirius looked confused for the first time.

"Severus, you leave her out of this," the werewolf growled.

"As I said once before, she is my friend… and you have been just as treacherous now as you were in school. Remember Lily?"

Sirius stared at his old friend.

"Lily?" he asked, slowly.

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

BANG! Thin, snake-like 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 towards 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 and Ron were watching all this with wide eyes, entirely bewildered; Hermione though, took a hesitant step forward. She had to believe, for Amelia's sake, that Remus had been honest – and despite her own anger she disliked the way that Severus was treating him. She had begun to think of them both as the most bizarre pair of uncles imaginable… she had to try.

"Professor Snape," she began breathlessly. "It – 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 snapped, his eyes still on Black. "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…"

But Snape was beyond reaching, his hatred of Black and the keen sense of betrayal he felt on behalf of himself and Amelia was coursing through him.

"KEEP QUIET, YOU STUPID GIRL!" he 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 pointing at Black's face. Hermione fell silent, afraid of what she might make him do.

"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," snarled Black. "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…"

What little colour there was in Black's face left it; on the floor, Remus renewed his struggle with the ropes that bound him.

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

But there was a glint in Snape's eye that Hermione 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."

To Hermione's surprise, Harry moved swiftly across the room 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 defence 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," Snape hissed. "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 shouted, deeply offended. "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!"

Amelia finished off the last of the third year papers with a flourish and a yawn. Stretching, she rose, before gathering up the pile and heading down the main staircase to Minerva's office. As she waited for the staircase in front of her to decide where it was going, she looked out over the lake. The sun was setting, spilling blood red light over the darkening grounds. She shivered; in all likelihood, Buckbeak was dying out there, somewhere in the crimson tide of darkness.

Sickened, she continued towards the deputy headmistress's quarters and knocked lightly on the wood.

"Come in."

Amelia pushed the door open with her shoulder and deposited the sheaf of exam papers on a specially cleared shelf. There were already a few stacks of papers in random positions.

Minerva McGonagall was stood by the window, looking out to the sunset. Sighing, the older witch turned to her.

"Forgive me, I was just thinking about Rubeus."

Amelia nodded.

"Perhaps we should go down tomorrow to see he's alright, he seems awfully attached to Beaky," she shrugged helplessly. "It seems so cruel to ask for his death… If the boy had only paid attention to Hagrid's instructions instead of trying to impress his cronies then none of this would have happened," she finished, hotly.

Minerva, who had of course taken the view that Hagrid should have kept a closer eye on his students, had to agree. She sat down heavily in her chair.

"I'd best be off," said Amelia sadly. "I promised Remus I'd sit with him tonight."

Minerva smiled at her.

"You're good for him, you know – and he for you. It's pleasant to see the two of you so happy."

Amelia grinned, despite herself.

"As you're heading that way, would you mind taking him Martin's scripts for second marking?"

"No problem," smiled the younger witch, picking up a hefty stack of Ancient Runes papers before bidding Minerva a good night and, more cheerful at the prospect of spending time with Remus, heading out of the door humming to herself.

Minerva watched her go, sadly. It had been a long time since she and Timothy had first sorted themselves out, but she could see herself in this young witch, and her relationship with Remus brought back bittersweet memories of her own courtship. Wearily, she put down her emerald green quill and steepled her fingers.

Having Remus around was also a reminder of his school friends. Oh, she'd been exasperated by their constant pranks (and privately certain that Remus had been the mastermind behind a lot of them), and they'd provoked her fury on more than one occasion, but she'd been secretly proud of them in their day. Then there had been dear, sweet Lily Evans; kind, studious, a diligent prefect – but also prepared to turn her brilliant mind to mischief. Minerva chuckled as she recalled disciplining her for a mysterious cloud of taunting and spitting hummingbirds that had somehow taken up residence around the head of a seventh-year Slytherin that had had the misfortune to call Lily a mud-blood. She had taken her punishment with a small smile and a sparkle in her eye that the two women had shared happily.

Sniffing, Minerva extracted her handkerchief from the desk drawer and blew her nose.

Such good people, she thought sadly, all destroyed by one boy's lust for power.

She missed them all terribly.

It took approximately three minutes for Amelia's good mood to dissipate. Three Ravenclaw fourth-years, caught up in the excitement of having finished their exams, came sprinting around a corner and knocked Amelia, along with Martin's exam papers, flying. They were clearly very sorry, so she let them off with a carpeting before collecting up the papers with bad grace and stomping up the stairs.

The castle was quiet in the post-exam hush and Amelia could hear the soft puffs of the lanterns around her bursting to life. It was a little eerie; she quickened her pace.

All of a sudden, she felt the cold prickle of fear that meant Hermione was afraid shiver down her back.

Convincing herself that her cousin had, as expected, stolen out of the castle to be with Hagrid during Buckbeak's execution she steeled herself before hurrying forward. This unease plainly meant that the dreadful act had been committed; Amelia felt the need to be near Remus, and to have him tell her that everything would be all right. Hermione, she knew, would have Harry and Ron by her side.

It was all that she could do not to run.

As she hurried to the last corner before Remus's office she was knocked backwards in a swirl of black robes and exam papers. Winded, Amelia looked up in time to see a pale and breathless Severus set off at a sprint.

Finding herself unexpectedly on her arse for the second time that evening – and more than a little alarmed at the countenance of her friend – she shouted after him angrily. So intent was he on his purpose that he didn't seem to hear her.

Swearing, Amelia picked herself up and rubbed her arse. That had hurt.

Gathering up the papers once more, she wondered what could possess her sombre friend to move at such a high speed.

Probably escaping from Sybill, she mused.

Huffily, she nudged open the door to Remus's office.

Funny, she thought, that lamp's gone over.

"Remus?" she called.

She glanced at the desk. The steaming goblet of Wolfsbane was still there, untouched.

Slowly, she put the pile of scripts down on a chair and walked around the desk, eyes on the Potion; a dark sense of foreboding was settling on her stomach and she was strongly reminded of that awful night two summers back, when she'd pelted through the streets of her home town, desperately afraid of what she might find.

Remus had knocked his inkwell over in his haste to leave, so she righted that and the lamp, absently replacing the spilled ink with a flick of her wand.

The Marauders' Map lay open in front of her; tensely she watched Severus pause by the Whomping Willow before running along the tunnel marked alongside it and disappearing off the edge of the map.

That settled it, really. Hermione and her friends were in trouble, and Remus and Severus had seen them on the Map.

Hermione is in trouble.

Amelia sped through the corridors of the castle at a pace that would have surprised her colleagues.

Hermione is in trouble, and so is Remus.

The warm air hit her as she crossed the courtyard, her footsteps heavy on the wooden bridge leading into the grounds.

Hermione is in trouble and it's probably Black.

Soil and twigs flew up around her as she tore across the grounds towards the Whomping Willow, which cast an eerily still silhouette in the moonlight.

She slowed, stopping where she judged the range of the great tree ended, breathing heavily.

Hermione is in trouble, and probably in the same room as a mass murderer.

Her face set and she strode forward with determination. Whatever it was that had allowed Severus and her cousin's entry into the tunnel held for Amelia too, but only just – her feet had barely touched the soft earth of the tunnel when an enormous branch smacked into the entrance behind her head.

Amelia ran along the tunnel, bent almost double.

Hermione is in trouble.

Behind her, she could hear the sound of the great tree's branches punish the earth around it until, apparently satisfied, the noises ceased.

Remus is in trouble, probably with Hermione.

She ran on. The tunnel seemed to be an endless tube of rock and dust; she felt her chest tighten as her claustrophobia kicked in. Ignoring it as best she could, she pressed on.

Hermione and Remus are in trouble.

After what seemed like an age she saw a pale light ahead; she drew her wand and climbed through the dusty opening.

Amelia barely had time to register the splintered furniture and stained floor as she heard raised voices ring out from above her.

Hermione.

She rushed up the stairs.

Severus's voice could be heard clearly now.

"GET OUT OF THE WAY POTTER!"

"Expelliarmus!"

The moment before Amelia kicked the door open a rush of magic flew across the dusty room in front of her. There was a blast that made the door rattle on its hinges; Severus 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 cold.

Wand up, Amelia moved into the room, looking from Severus against the wall, to Remus bound and struggling at her feet, to the children stood around the bed, and in front of her, Sirius Black. It occurred to her that as Black appeared to be unarmed Hermione or her friends must have disarmed Severus.

She kept her wand and eyes fixed on Black; pale, filthy and gaunt as he was, he looked shaken.

She was aware that the children were staring at her.

"Hermione?"

"I'm ok," replied the younger witch anxiously, "and so's Harry… I think Ron's leg's broken."

Amelia nodded.

"Untie Remus, please."

Hermione crossed the room and bent down to free her Professor.

"I take it you three had a good reason for knocking Severus out?" she said evenly.

"He'd gone mad," said Harry quietly.

"You shouldn't have done that," said Black, looking at Harry. "You should have left him to me."

Amelia shuddered. Hermione had untied Remus and returned to Ron's side a little too quickly for Amelia's taste. She was muttering "We attacked a teacher, we attacked a teacher," under her breath, over and over.

She glanced at Remus.

"You alright?"

"Just a few bruises… Amelia, lower your wand," he said, carefully.

Bewildered, Amelia risked another look at him. He had his hands up in a placating manner; the fear in her stomach curled into a knot.

"I most certainly will not!"

"Please – just let me explain –"

"Remus, your stories are taking too long," growled Black.

"Shut up, Sirius!" he snapped, urgently.

Amelia's eyes flicked rapidly between the two men.

"Sirius?" she asked, and took a step backwards, staggered. "Remus –" she pleaded.

"Really Mel, I can explain –" he said, desperation in his voice. Black looked from Remus to Amelia, something akin to curiosity in his dark eyes.

She shook her head in horror.

"All those times you told me you hated him for what he'd done, and I believed you!"

"Amelia, please –"

"I comforted you, you lying bastard!" she spat.

"Mel –"

Her voice was far softer now; Amelia looked him dead in the eye.

"You should know, Lupin, that if you hurt my cousin, I will kill you."

There was an icy silence. Black was now staring between Amelia and his old friend; she could hear Ron's ragged breathing from the bed to her right.

Remus's shoulders had sagged and his eyes were closed.

He looked, Hermione said later, as if his entire world had collapsed.

He straightened up and addressed Harry instead, voice terse.

"Thank you."

"I want you three to go back up to the castle," Amelia said over her shoulder. "Fetch anyone you can find – I'll stay here and watch these two."

Black took a step towards her.

"That boy's not taking his rat anywhere," he hissed threateningly.

The tip of her wand was touching his chest now; Amelia realised with painful clarity that if he wanted to, Black could simply reach up and take it from her… but why wasn't he? Remus pushed him back, placing himself between Black and the point of her wand.

"Don't."

"Remus –"

"Please."

"Twelve years!" he moaned.

"I know," Lupin sighed and turned to face her.

"I give you my word, Amelia, that neither Sirius nor I will harm you or any of the children."

She swallowed.

"I don't know how much your word's worth any more."

"I promise you, no harm will come –" he began again, but she cut across him, angrily.

"And I suppose Ron's leg broke all of its own accord, did it?"

He looked at her helplessly.

"You're evil," she whispered.

Harry spoke up.

"Professor Brown? I know it sounds mad, but they think Ron's rat is a wizard."

Amelia thought about this for a moment.

"Ok, maybe not evil. Deranged."

"It's the truth, Mel."

There was a pause, then –

"I'm sorry, I don't quite see what the hell that has to do with anything."

Hermione stepped forward; Amelia glanced at her in the gloom, feeling they were becoming somewhat sidetracked.

"Black says that he didn't kill Harry's parents, they were betrayed by Peter Pettigrew, their old friend."

Amelia frowned. "But he's dead," she said slowly, as if trying to explain something simple to Crabbe or Goyle.

"No he's not," said Remus. Behind him, Black gave a menacing growl.

"He soon will be!"

"Professor Lupin says that Pettigrew is an unregistered Animagus – like Black," Hermione continued timidly.

"An Animagus," Amelia repeated, slowly.

"He's a dog," said Ron, from the bed, "… I saw him change back."

Amelia looked at Remus, head tilted a little to the right as if trying to understand.

"A dog," she said, "and a rat."

Remus nodded.

"… Padfoot… and Wormtail…"

"Yes," he replied quietly.

Amelia shook her head again.

"Hermione?" she asked; it was unnecessary to finish the question.

"I… I think we should listen to them."

Still very unhappy, Amelia gave a curt nod and moved between the two men and the children. She didn't lower her wand.

"Go on then."
