“—he’s complained to the school governors. And to the Ministry of Magic. Father’s got a lot of influence, you know. And a lasting injury like this”—he gave a huge, fake sigh—“who knows if my arm’ll ever be the same again?”

“So that’s why you’re putting it on,” said Harry, accidentally beheading a dead caterpillar because his hand was shaking in anger. “To try to get Hagrid fired.”

“Well,” said Malfoy, lowering his voice to a whisper, “partly, Potter. But there are other benefits too. Weasley, slice my caterpillars for me.”

A few cauldrons away, Neville was in trouble. Neville regularly went to pieces in Potions lessons; it was his worst subject, and his great fear of Professor Snape made things ten times worse. His potion, which was supposed to be a bright, acid green, had turned—

“Orange, Longbottom,” said Snape, ladling some up and allowing it to splash back into the cauldron, so that everyone could see. “Orange. Tell me, boy, does anything penetrate that thick skull of yours? Didn’t you hear me say, quite clearly, that only one rat spleen was needed? Didn’t I state plainly that a dash of leech juice would suffice? What do I have to do to make you understand, Longbottom?”

Neville was pink and trembling. He looked as though he was on the verge of tears.

“Please, sir,” said Hermione, “please, I could help Neville put it right—”

“I don’t remember asking you to show off, Miss Granger,” said Snape coldly, and Hermione went as pink as Neville. “Longbottom, at the end of this lesson we will feed a few drops of this potion to your toad and see what happens. Perhaps that will encourage you to do it properly.”

Snape moved away, leaving Neville breathless with fear.

“Help me!” he moaned to Hermione.

“Hey, Harry,” said Seamus Finnigan, leaning over to borrow Harry’s brass scales, “have you heard? Daily Prophet this morning—they reckon Sirius Black’s been sighted.”

“Where?” said Harry and Ron quickly. On the other side of the table, Malfoy looked up, listening closely.

“Not too far from here,” said Seamus, who looked excited. “It was a Muggle who saw him. ’Course, she didn’t really understand. The Muggles think he’s just an ordinary criminal, don’t they? So she phoned the telephone hot line. By the time the Ministry of Magic got there, he was gone.”

“Not too far from here . . . ,” Ron repeated, looking significantly at Harry. He turned around and saw Malfoy watching closely. “What, Malfoy? Need something else skinned?”

But Malfoy’s eyes were shining malevolently, and they were fixed on Harry. He leaned across the table.

“Thinking of trying to catch Black single-handed, Potter?”

“Yeah, that’s right,” said Harry offhandedly.

Malfoy’s thin mouth was curving in a mean smile.
