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?”
“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.”
