“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.

“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?”
