Passages.

Two weeks before the end of the term, the sky lightened suddenly to a dazzling, opaline white and the muddy grounds were revealed one morning covered in glittering frost. Inside the castle, there was a buzz of Christmas in the air. Professor Flitwick, the Charms teacher, had already decorated his classroom with shimmering lights that turned out to be real, fluttering fairies. The students were all happily discussing their plans for the holidays. Both Ron and Hermione had decided to remain at Hogwarts, and though Ron said it was because he couldn't stand two weeks with Percy, and Hermione insisted she needed to use the library, Harry wasn't fooled; they were doing it to keep him company, and he was very grateful.

To everyone's delight except Harry's, there was to be another Hogsmeade trip on the very last weekend of the term.

"We can do all our Christmas shopping there!" said Hermione. "Mum and Dad would really love those Toothflossing Stringmints from Honeydukes!"

Resigned to the fact that he would be the only third year staying behind again, Harry borrowed a copy of Which Broomstick from Wood, and decided to spend the day reading up on the different makes. He had been riding one of the school brooms at team practice, an ancient Shooting Star, which was very slow and jerky; he definitely needed a new broom of his own.

On the Saturday morning of the Hogsmeade trip, Harry bid good-bye to Ron and Hermione, who were wrapped in cloaks and scarves, then turned up the marble staircase alone, and headed back toward Gryffindor Tower. Snow had started to fall outside the windows, and the castle was very still and quiet.

"Psst -- Harry!"

He turned, halfway along the third-floor corridor, to see Fred and George peering out at him from behind a statue of a humpbacked, one-eyed witch.

"What are you doing?" said Harry curiously. "How come you're not going to Hogsmeade?"

"We've come to give you a bit of festive cheer before we go," said Fred, with a mysterious wink. "Come in here..."

He nodded toward an empty classroom to the left of the one-eyed statue. Harry followed Fred and George inside. George closed the door quietly and then turned, beaming, to look at Harry.

"Early Christmas present for you, Harry," he said.

Fred pulled something from inside his cloak with a flourish and laid it on one of the desks. It was a large, square, very worn piece of parchment with nothing written on it. Harry, suspecting one of Fred and George's jokes, stared at it.

"What's that supposed to be?"

"This, Harry, is the secret of our success," said George, patting the parchment fondly.

"It's a wrench, giving it to you," said Fred, "but we decided last night, your need's greater than ours."

"Anyway, we know it by heart," said George. "We bequeath it to you. We don't really need it anymore."

"And what do I need with a bit of old parchment?" said Harry.

"A bit of old parchment!" said Fred, closing his eyes with a grimace as though Harry had mortally offended him. "Explain, George."

"Well...when we were in our first year, Harry -- young, carefree, and innocent --"

Harry snorted. He doubted whether Fred and George had ever been innocent.

"¨C well, more innocent than we are now -- we got into a spot of bother with Filch."

"We let off a Dungbomb in the corridor and it upset him for some reason --"

"So he hauled us off to his office and started threatening us with the usual --"

"-- detention --"

"-- disembowelment --"

"-- and we couldn't help noticing a drawer in one of his filing cabinets marked Confiscated and Highly Dangerous."

"Don't tell me --" said Harry, starting to grin.

"Well, what would you've done?" said Fred. "George caused a diversion by dropping another Dungbomb, I whipped the drawer open, and grabbed -- this."

"It's not as bad as it sounds, you know," said George. "We don't reckon Filch ever found out how to work it. He probably suspected what it was, though, or he wouldn't have confiscated it."

"And you know how to work it?"

"Oh yes," said Fred, smirking. "This little beauty's taught us more than all the teachers in this school."

"You're winding me up," said Harry, looking at the ragged old bit of parchment.

"Oh, are we?" said George.

He took out his wand, touched the parchment lightly, and said, "I solemnly swear that I am up to no good."

And at once, thin ink lines began to spread like a spider's web from the point that George's wand had touched. They joined each other, they crisscrossed, they fanned into every corner of the parchment; then words began to blossom across the top, great, curly green words, that proclaimed:

Messrs. Moony, Wormtail, Padfoot, and Prongs

Purveyors of Aids to Magical Mischief-Makers

are proud to present

THE MARAUDER'S MAP

It was a map showing every detail of the Hogwarts castle and grounds. But the truly remarkable thing were the tiny ink dots moving around it, each labeled with a name in minuscule writing. Astounded, Harry bent over it. A labeled dot in the top left corner showed that Professor Dumbledore was pacing his study; the caretaker's cat, Mrs. Norris, was prowling the second floor; and Peeves the Poltergeist was currently bouncing around the trophy room. And as Harry's eyes traveled up and down the familiar corridors, he noticed something else.

This map showed a set of passages he had never entered. And many of them seemed to lead --
