Sirius looked different from Harry’s memory of him. When they had said good-bye, Sirius’s face had been gaunt and sunken, surrounded by a quantity of long, black, matted hair—but the hair was short and clean now, Sirius’s face was fuller, and he looked younger, much more like the only photograph Harry had of him, which had been taken at the Potters’ wedding.

“Never mind me, how are you?” said Sirius seriously.

“I’m—” For a second, Harry tried to say “fine”—but he couldn’t do it. Before he could stop himself, he was talking more than he’d talked in days—about how no one believed he hadn’t entered the tournament of his own free will, how Rita Skeeter had lied about him in the Daily Prophet, how he couldn’t walk down a corridor without being sneered at—and about Ron, Ron not believing him, Ron’s jealousy . . .

“ . . . and now Hagrid’s just shown me what’s coming in the first task, and it’s dragons, Sirius, and I’m a goner,” he finished desperately.

Sirius looked at him, eyes full of concern, eyes that had not yet lost the look that Azkaban had given them—that deadened, haunted look. He had let Harry talk himself into silence without interruption, but now he said, “Dragons we can deal with, Harry, but we’ll get to that in a minute—I haven’t got long here . . . I’ve broken into a wizarding house to use the fire, but they could be back at any time. There are things I need to warn you about.”

“What?” said Harry, feeling his spirits slip a further few notches . . . Surely there could be nothing worse than dragons coming?

“Karkaroff,” said Sirius. “Harry, he was a Death Eater. You know what Death Eaters are, don’t you?”

“Yes—he—what?”

“He was caught, he was in Azkaban with me, but he got released. I’d bet everything that’s why Dumbledore wanted an Auror at Hogwarts this year—to keep an eye on him. Moody caught Karkaroff. Put him into Azkaban in the first place.”

“Karkaroff got released?” Harry said slowly—his brain seemed to be struggling to absorb yet another piece of shocking information. “Why did they release him?”

“He did a deal with the Ministry of Magic,” said Sirius bitterly. “He said he’d seen the error of his ways, and then he named names . . . he put a load of other people into Azkaban in his place . . . He’s not very popular in there, I can tell you. And since he got out, from what I can tell, he’s been teaching the Dark Arts to every student who passes through that school of his. So watch out for the Durmstrang champion as well.”
