Crabbe blundered forward, his long arms outstretched like a zombie. Harry dodged around him, picked up a stick, and lobbed it at Crabbe’s back. Harry doubled up with silent laughter as Crabbe did a kind of pirouette in midair, trying to see who had thrown it. As Ron was the only person Crabbe could see, it was Ron he started toward, but Harry stuck out his leg. Crabbe stumbled—and his huge, flat foot caught the hem of Harry’s cloak. Harry felt a great tug, then the cloak slid off his face.

For a split second, Malfoy stared at him.

“AAARGH!” he yelled, pointing at Harry’s head. Then he turned tail and ran, at breakneck speed, back down the hill, Crabbe and Goyle behind him.

Harry tugged the cloak up again, but the damage was done.

“Harry!” Ron said, stumbling forward and staring hopelessly at the point where Harry had disappeared, “you’d better run for it! If Malfoy tells anyone—you’d better get back to the castle, quick—”

“See you later,” said Harry, and without another word, he tore back down the path toward Hogsmeade.

Would Malfoy believe what he had seen? Would anyone believe Malfoy? Nobody knew about the Invisibility Cloak—nobody except Dumbledore. Harry’s stomach turned over—Dumbledore would know exactly what had happened, if Malfoy said anything—

Back into Honeydukes, back down the cellar steps, across the stone floor, through the trapdoor—Harry pulled off the cloak, tucked it under his arm, and ran, flat out, along the passage . . . Malfoy would get back first . . . how long would it take him to find a teacher? Panting, a sharp pain in his side, Harry didn’t slow down until he reached the stone slide. He would have to leave the cloak where it was, it was too much of a giveaway in case Malfoy had tipped off a teacher—he hid it in a shadowy corner, then started to climb, fast as he could, his sweaty hands slipping on the sides of the chute. He reached the inside of the witch’s hump, tapped it with his wand, stuck his head through, and hoisted himself out; the hump closed, and just as Harry jumped out from behind the statue, he heard quick footsteps approaching.

It was Snape. He approached Harry at a swift walk, his black robes swishing, then stopped in front of him.

“So,” he said.

There was a look of suppressed triumph about him. Harry tried to look innocent, all too aware of his sweaty face and his muddy hands, which he quickly hid in his pockets.

“Come with me, Potter,” said Snape.

Harry followed him downstairs, trying to wipe his hands clean on the inside of his robes without Snape noticing. They walked down the stairs to the dungeons and then into Snape’s office.
