Harry had been in here only once before, and he had been in very serious trouble then too. Snape had acquired a few more slimy horrible things in jars since last time, all standing on shelves behind his desk, glinting in the firelight and adding to the threatening atmosphere.

“Sit,” said Snape.

Harry sat. Snape, however, remained standing.

“Mr. Malfoy has just been to see me with a strange story, Potter,” said Snape.

Harry didn’t say anything.

“He tells me that he was up by the Shrieking Shack when he ran into Weasley—apparently alone.”

Still, Harry didn’t speak.

“Mr. Malfoy states that he was standing talking to Weasley, when a large amount of mud hit him in the back of the head. How do you think that could have happened?”

Harry tried to look mildly surprised.

“I don’t know, Professor.”

Snape’s eyes were boring into Harry’s. It was exactly like trying to stare down a hippogriff. Harry tried hard not to blink.

“Mr. Malfoy then saw an extraordinary apparition. Can you imagine what it might have been, Potter?”

“No,” said Harry, now trying to sound innocently curious.

“It was your head, Potter. Floating in midair.”

There was a long silence.

“Maybe he’d better go to Madam Pomfrey,” said Harry. “If he’s seeing things like—”

“What would your head have been doing in Hogsmeade, Potter?” said Snape softly. “Your head is not allowed in Hogsmeade. No part of your body has permission to be in Hogsmeade.”

“I know that,” said Harry, striving to keep his face free of guilt or fear. “It sounds like Malfoy’s having hallucin—”

“Malfoy is not having hallucinations,” snarled Snape, and he bent down, a hand on each arm of Harry’s chair, so that their faces were a foot apart. “If your head was in Hogsmeade, so was the rest of you.”

“I’ve been up in Gryffindor Tower,” said Harry. “Like you told—”

“Can anyone confirm that?”

Harry didn’t say anything. Snape’s thin mouth curled into a horrible smile.

“So,” he said, straightening up again. “Everyone from the Minister of Magic downward has been trying to keep famous Harry Potter safe from Sirius Black. But famous Harry Potter is a law unto himself. Let the ordinary people worry about his safety! Famous Harry Potter goes where he wants to, with no thought for the consequences.”

Harry stayed silent. Snape was trying to provoke him into telling the truth. He wasn’t going to do it. Snape had no proof—yet.

“How extraordinarily like your father you are, Potter,” Snape said suddenly, his eyes glinting. “He too was exceedingly arrogant. A small amount of talent on the Quidditch field made him think he was a cut above the rest of us too. Strutting around the place with his friends and admirers . . . The resemblance between you is uncanny.”

“My dad didn’t strut,” said Harry, before he could stop himself. “And neither do I.”
