"Why wouldn't he give you a trial?" I asked.

"That is a very good question, especially considering people like the Lestrange's were, and unlike me, they actually did some incredibly horrific things" Sirius replied. "I think they probably considered the fact that everyone on that street were convinced they saw me kill Pettigrew and those muggles, that there was no reason to hold a trial. In their minds, I was obviously guilty"

"Couldn't they have just used Veriterserum or viewed your memories in a Pensive?" said Hermione

"Believe it or not, neither was an option at the time. They were both invented as contingencies in case of a second war" said Sirius. "In any case, they'd have probably said I was either somehow resisting, had an antidote, or created some false memories. He was tipped for the next Minister of Magic. He's a great wizard, Barty Crouch, powerfully magical — and power-hungry. Oh never a Voldemort supporter," he said, reading the look on Harry's face. "No, Barty Crouch was always very outspoken against the Dark Side. But then a lot of people who were against the Dark Side . . . well, you wouldn't understand . . . you're too young. . . ."

"That's what my dad said at the World Cup," said Ron, with a trace of irritation in his voice. "Try us, why don't you?"

A grin flashed across Sirius's thin face. "All right, I'll try you. . . ." He walked once up the cave, back again, and then said, "Imagine that Voldemort's powerful now. You don't know who his supporters are, you don't know who's working for him and who isn't; you know he can control people so that they do terrible things without being able to stop themselves. You're scared for yourself, and your family, and your friends. Every week, news comes of more deaths, more disappearances, more torturing . . . the Ministry of Magic's in disarray, they don't know what to do, they're trying to keep everything hidden from the Muggles, but meanwhile, Muggles are dying too. Terror everywhere . . . panic . . . confusion . . . that's how it used to be.

"Well, times like that bring out the best in some people and the worst in others. Crouch's principles might've been good in the beginning — I wouldn't know. He rose quickly through the Ministry, and he started ordering very harsh measures against Voldemort's supporters. The Aurors were given new powers — powers to kill rather than capture, for instance. And I wasn't the only one who was handed straight to the dementors without trial, I often wonder if there's anyone else in Azkaban that was falsely accused like me.

"Crouch fought violence with violence, and authorized the use of the Unforgivable Curses against suspects. I would say he became as ruthless and cruel as many on the Dark Side. He had his supporters, mind you — plenty of people thought he was going about things the right way, and there were a lot of witches and wizards clamoring for him to take over as Minister of Magic. When Voldemort disappeared, it looked like only a matter of time until Crouch got the top job. But then something rather unfortunate happened. . . ." Sirius smiled grimly. "Crouch's own son was caught with a group of Death Eaters who'd managed to talk their way out of Azkaban. Apparently they were trying to find Voldemort and return him to power."

"Crouch's son was caught?" gasped Hermione.

"Yep," said Sirius, throwing his chicken bone to Buckbeak, flinging himself back down on the ground beside the loaf of bread, and tearing it in half. "Nasty little shock for old Barty, I'd imagine. Should have spent a bit more time at home with his family, shouldn't he? Ought to have left the office early once in a while . . . gotten to know his own son." He began to wolf down large pieces of bread.

"Was his son a Death Eater?" said Harry.

"No idea," said Sirius, still stuffing down bread. "I was in Azkaban myself when he was brought in. This is mostly stuff I've found out since I got out. The boy was definitely caught in the company of people I'd bet my life were Death Eaters — but he might have been in the wrong place at the wrong time, just like the house-elf."

"Did Crouch try and get his son off?" Hermione whispered.

Sirius let out a laugh that was much more like a bark. "Crouch let his son off? I thought you had the measure of him, Hermione! Anything that threatened to tarnish his reputation had to go; he had dedicated his whole life to becoming Minister of Magic. You saw him dismiss a devoted house-elf because she associated him with the Dark Mark again — doesn't that tell you what he's like? Crouch's fatherly affection stretched just far enough to give his son a trial, and by all accounts, it wasn't much more than an excuse for Crouch to show how much he hated the boy . . . then he sent him straight to Azkaban."

"He gave his own son to the dementors?" asked Harry quietly

"My god..." said Demelza

"That must have been brutal for both of them" added Amy "and I might be about to give my own uncle to them, I can understand how Crouch might have felt, though Ludo's crimes are much more minor..."

"That's right," said Sirius, and he didn't look remotely amused now. "I saw the dementors bringing him in, watched them through the bars in my cell door. He can't have been more than nineteen. They took him into a cell near mine. He was screaming for his mother by nightfall. He went quiet after a few days, though . . . they all went quiet in the end . . . except when they shrieked in their sleep. . . ." For a moment, the deadened look in Sirius's eyes became more pronounced than ever, as though shutters had closed behind them.

"So he's still in Azkaban?" Harry said.

"No," said Sirius dully. "No, he's not in there anymore. He died about a year after they brought him in."

"He died?"

"He wasn't the only one," said Sirius bitterly. "Most go mad in there, and plenty stop eating in the end. They lose the will to live. You could always tell when a death was coming, because the dementors could sense it, they got excited. That boy looked pretty sickly when he arrived. Crouch being an important Ministry member, he and his wife were allowed a deathbed visit. That was the last time I saw Barty Crouch, half carrying his wife past my cell. She died herself, apparently, shortly afterward. Grief. Wasted away just like the boy. Crouch never came for his son's body. The dementors buried him outside the fortress; I watched them do it."

Sirius threw aside the bread he had just lifted to his mouth and instead picked up the flask of pumpkin juice and drained it.

"So old Crouch lost it all, just when he thought he had it made," he continued, wiping his mouth with the back of his hand. "One moment, a hero, poised to become Minister of Magic . . . next, his son dead, his wife dead, the family name dishonored, and, so I've heard since I escaped, a big drop in popularity. Once the boy had died, people started feeling a bit more sympathetic toward the son and started asking how a nice young lad from a good family had gone so badly astray. The conclusion was that his father never cared much for him. So Cornelius Fudge got the top job, and Crouch was shunted sideways into the Department of International Magical Cooperation."

"Moody says Crouch is obsessed with catching Dark wizards," Harry told Sirius.

"That reminds me!" I said "there's someone called Richie Crouch in first year! Not sure what relation he is to Barty, but I assume it has to be a grandson considering his age. I'll ask him soon, see if we can find out from him what's been going on!"

"Good idea Ginny, and yeah, I've heard it's become a bit of a mania with him," said Sirius, nodding. "If you ask me, he still thinks he can bring back the old popularity by catching one more Death Eater."

"And he sneaked up here to search Snape's office!" said Ron triumphantly, looking at Hermione.

"Yes, and that doesn't make sense at all," said Sirius.

"Yeah, it does!" said Ron excitedly, but Sirius shook his head.

"Listen, if Crouch wants to investigate Snape, why hasn't he been coming to judge the tournament? It would be an ideal excuse to make regular visits to Hogwarts and keep an eye on him."

"So you think Snape could be up to something, then?" asked Harry, but Hermione broke in.

"Look, I don't care what you say, Dumbledore trusts Snape —"

"Oh give it a rest, Hermione," said Ron impatiently. "I know Dumbledore's brilliant and everything, but that doesn't mean a really clever Dark wizard couldn't fool him —"

"I agree with Hermione here" Demelza said "I don't see how Snape could have fooled Dumbledore for so long"

"Why did Snape save Harry's life in the first year, then? Why didn't he just let him die?" said Hermione

"I dunno — maybe he thought Dumbledore would kick him out —"

"What d'you think, Sirius?" Harry said loudly, and Ron and Hermione stopped bickering to listen.

"I think they've both got a point," said Sirius, looking thoughtfully at Ron and Hermione. "Ever since I found out Snape was teaching here, I've wondered why Dumbledore hired him. Snape's always been fascinated by the Dark Arts, he was famous for it at school. Slimy, oily, greasy-haired kid, he was," Sirius added, and Harry and Ron grinned at each other. "Snape knew more curses when he arrived at school than half the kids in seventh year, and he was part of a gang of Slytherins who nearly all turned out to be Death Eaters."

"Rosier and Wilkes — they were both killed by Aurors the year before Voldemort fell. The Lestranges — they're a married couple — they're in Azkaban. Avery — from what I've heard he wormed his way out of trouble by saying he'd been acting under the Imperius Curse — he's still at large"

"The Ministry trust him like they do Lucius Malfoy" Amy said

"We're very very familiar with his daughter Lillian, she's in our year" said Demelza darkly

"Myself especially" I said "She, along with Amy's sister-"

"SHE IS NOT MY SISTER!" Amy roared at me

I bit my lip

"Alright, yeah, sorry, I mean, she and someone called Sarah that Amy used to know attacked me in a deserted corridor one day, put me in St Mungo's, I was minutes from death. I reckon Avery's money is the only reason they're not in Azkaban, Sarah lives with them now. Lillian brainwashed her into joining them, she disowned Amy at the start of our second year"

"As far as I'm concerned, Sarah was never part of the family" Amy growled "the person I thought she was didn't actually exist and is not worthy of the Bagman name"

"Merlin, she had to be called Lillian didn't she..." Sirius trailed off, a pained expression on his face

"Yeah, the fact that bitch has a name even close to my mum's is horrible!" Harry spat

"She's gonna be a serious threat in the future, that's for sure" Demelza said

"I don't doubt that, especially if they let her finish her schooling" said Sirius, "but anyway, as far as I know, Snape was never even accused of being a Death Eater — not that that means much. Plenty of them were never caught. And Snape's certainly clever and cunning enough to keep himself out of trouble."

"Snape knows Karkaroff pretty well, but he wants to keep that quiet," said Ron.

"Yeah, you should've seen Snape's face when Karkaroff turned up in Potions yesterday!" said Harry quickly. "Karkaroff wanted to talk to Snape, he says Snape's been avoiding him. Karkaroff looked really worried. He showed Snape something on his arm, but I couldn't see what it was"

"He showed Snape something on his arm?" said Sirius, looking frankly bewildered. He ran his fingers distractedly through his filthy hair, then shrugged again. "Well, I've no idea what that's about . . . but if Karkaroff's genuinely worried, and he's going to Snape for answers . . ."
