“Says he’s taken a liking to me,” said Harry.

“Hmm,” said Sirius, looking thoughtful.

“We saw him in the forest just before the Dark Mark appeared,” Hermione told Sirius. “Remember?” she said to Harry and Ron.

“Yeah, but he didn’t stay in the forest, did he?” said Ron. “The moment we told him about the riot, he went off to the campsite.”

“How d’you know?” Hermione shot back. “How d’you know where he Disapparated to?”

“Come off it,” said Ron incredulously. “Are you saying you reckon Ludo Bagman conjured the Dark Mark?”

“It’s more likely he did it than Winky,” said Hermione stubbornly.

“Told you,” said Ron, looking meaningfully at Sirius, “told you she’s obsessed with house—”

But Sirius held up a hand to silence Ron.

“When the Dark Mark had been conjured, and the elf had been discovered holding Harry’s wand, what did Crouch do?”

“Went to look in the bushes,” said Harry, “but there wasn’t anyone else there.”

“Of course,” Sirius muttered, pacing up and down, “of course, he’d want to pin it on anyone but his own elf . . . and then he sacked her?”

“Yes,” said Hermione in a heated voice, “he sacked her, just because she hadn’t stayed in her tent and let herself get trampled—”

“Hermione, will you give it a rest with the elf!” said Ron.

Sirius shook his head and said, “She’s got the measure of Crouch better than you have, Ron. If you want to know what a man’s like, take a good look at how he treats his inferiors, not his equals.”

He ran a hand over his unshaven face, evidently thinking hard.

“All these absences of Barty Crouch’s . . . he goes to the trouble of making sure his house-elf saves him a seat at the Quidditch World Cup, but doesn’t bother to turn up and watch. He works very hard to reinstate the Triwizard Tournament, and then stops coming to that too . . . It’s not like Crouch. If he’s ever taken a day off work because of illness before this, I’ll eat Buckbeak.”

“D’you know Crouch, then?” said Harry.

Sirius’s face darkened. He suddenly looked as menacing as he had the night when Harry first met him, the night when Harry still believed Sirius to be a murderer.

“Oh I know Crouch all right,” he said quietly. “He was the one who gave the order for me to be sent to Azkaban—without a trial.”

“What?” said Ron and Hermione together.

“You’re kidding!” said Harry.

“No, I’m not,” said Sirius, taking another great bite of chicken. “Crouch used to be Head of the Department of Magical Law Enforcement, didn’t you know?”

Harry, Ron, and Hermione shook their heads.
