“Can you hear someone talking, Harry?” growled Ron, not looking at Hermione.

“Ron, how can you let him go with you? After what Sirius Black nearly did to you! I mean it, I’ll tell—”

“So now you’re trying to get Harry expelled!” said Ron furiously. “Haven’t you done enough damage this year?”

Hermione opened her mouth to respond, but with a soft hiss, Crookshanks leapt onto her lap. Hermione took one frightened look at the expression on Ron’s face, gathered up Crookshanks, and hurried away toward the girls’ dormitories.

“So how about it?” Ron said to Harry as though there had been no interruption. “Come on, last time we went you didn’t see anything. You haven’t even been inside Zonko’s yet!”

Harry looked around to check that Hermione was well out of earshot.

“Okay,” he said. “But I’m taking the Invisibility Cloak this time.”

On Saturday morning, Harry packed his Invisibility Cloak in his bag, slipped the Marauder’s Map into his pocket, and went down to breakfast with everyone else. Hermione kept shooting suspicious looks down the table at him, but he avoided her eye and was careful to let her see him walking back up the marble staircase in the entrance hall as everybody else proceeded to the front doors.

“’Bye!” Harry called to Ron. “See you when you get back!”

Ron grinned and winked.

Harry hurried up to the third floor, slipping the Marauder’s Map out of his pocket as he went. Crouching behind the one-eyed witch, he smoothed it out. A tiny dot was moving in his direction. Harry squinted at it. The minuscule writing next to it read Neville Longbottom.

Harry quickly pulled out his wand, muttered, “Dissendium!” and shoved his bag into the statue, but before he could climb in himself, Neville came around the corner.

“Harry! I forgot you weren’t going to Hogsmeade either!”

“Hi, Neville,” said Harry, moving swiftly away from the statue and pushing the map back into his pocket. “What are you up to?”

“Nothing,” shrugged Neville. “Want a game of Exploding Snap?”

“Er—not now—I was going to go to the library and do that vampire essay for Lupin—”

“I’ll come with you!” said Neville brightly. “I haven’t done it either!”

“Er—hang on—yeah, I forgot, I finished it last night!”

“Great, you can help me!” said Neville, his round face anxious. “I don’t understand that thing about the garlic at all—do they have to eat it, or—”

He broke off with a small gasp, looking over Harry’s shoulder.

It was Snape. Neville took a quick step behind Harry.

“And what are you two doing here?” said Snape, coming to a halt and looking from one to the other. “An odd place to meet—”

To Harry’s immense disquiet, Snape’s black eyes flicked to the doorways on either side of them, and then to the one-eyed witch.
