A seam had split on Hermione’s bag. Harry wasn’t surprised; he could see that it was crammed with at least a dozen large and heavy books.
“Why are you carrying all these around with you?” Ron asked her.
“You know how many subjects I’m taking,” said Hermione breathlessly. “Couldn’t hold these for me, could you?”
“But—” Ron was turning over the books she had handed him, looking at the covers. “You havent got any of these subjects today. It’s only Defense Against the Dark Arts this afternoon.”
“Oh yes,” said Hermione vaguely, but she packed all the books back into her bag just the same. “I hope there’s something good for lunch, I’m starving,” she added, and she marched off toward the Great Hall.
“D’you get the feeling Hermione’s not telling us something?” Ron asked Harry.
Professor Lupin wasn’t there when they arrived at his first Defense Against the Dark Arts lesson. They all sat down, took out their books, quills, and parchment, and were talking when he finally entered the room. Lupin smiled vaguely and placed his tatty old briefcase on the teacher’s desk. He was as shabby as ever but looked healthier than he had on the train, as though he had had a few square meals.
“Good afternoon,” he said. “Would you please put all your books back in your bags. Today’s will be a practical lesson. You will need only your wands.”
A few curious looks were exchanged as the class put away their books. They had never had a practical Defense Against the Dark Arts before, unless you counted the memorable class last year when their old teacher had brought a cageful of pixies to class and set them loose.
“Right then,” said Professor Lupin, when everyone was ready. “If you’d follow me.”
Puzzled but interested, the class got to its feet and followed Professor Lupin out of the classroom. He led them along the deserted corridor and around a corner, where the first thing they saw was Peeves the Poltergeist, who was floating upside down in midair and stuffing the nearest keyhole with chewing gum.
Peeves didn’t look up until Professor Lupin was two feet away, then he wiggled his curly toed feet and broke into song.
Rude and unmanageable as he almost always was, Peeves usually showed some respect toward the teachers. Everyone looked quickly at Professor Lupin to see how he would take this; to their surprise, he was still smiling.
“I’d take that gum out of the keyhole if I were you, Peeves,” he said pleasantly. “Mr. Filch won’t be able to get in to his brooms.”
Filch was the Hogwarts caretaker, a bad tempered, failed wizard who waged a constant war against the students and, indeed, Peeves. However, Peeves paid no attention to Professor Lupin’s words, except to blow a loud wet raspberry.
