And then, halfway down the staircase, not thinking about what he was doing, not concentrating on anything but the peculiar behavior of Mr. Crouch, Harry’s leg suddenly sank right through the trick step Neville always forgot to jump. He gave an ungainly wobble, and the golden egg, still damp from the bath, slipped from under his arm. He lurched forward to try and catch it, but too late; the egg fell down the long staircase with a bang as loud as a bass drum on every step—the Invisibility Cloak slipped—Harry snatched at it, and the Marauder’s Map fluttered out of his hand and slid down six stairs, where, sunk in the step to above his knee, he couldn’t reach it.

The golden egg fell through the tapestry at the bottom of the staircase, burst open, and began wailing loudly in the corridor below. Harry pulled out his wand and struggled to touch the Marauder’s Map, to wipe it blank, but it was too far away to reach—

Pulling the cloak back over himself Harry straightened up, listening hard with his eyes screwed up with fear . . . and, almost immediately—

“PEEVES!”

It was the unmistakable hunting cry of Filch the caretaker. Harry could hear his rapid, shuffling footsteps coming nearer and nearer, his wheezy voice raised in fury.

“What’s this racket? Wake up the whole castle, will you? I’ll have you, Peeves, I’ll have you, you’ll . . . and what is this?”

Filch’s footsteps halted; there was a clink of metal on metal and the wailing stopped—Filch had picked up the egg and closed it. Harry stood very still, one leg still jammed tightly in the magical step, listening. Any moment now, Filch was going to pull aside the tapestry, expecting to see Peeves . . . and there would be no Peeves . . . but if he came up the stairs, he would spot the Marauder’s Map . . . and Invisibility Cloak or not, the map would show “Harry Potter” standing exactly where he was.

“Egg?” Filch said quietly at the foot of the stairs. “My sweet!”—Mrs. Norris was obviously with him—“This is a Triwizard clue! This belongs to a school champion!”

Harry felt sick; his heart was hammering very fast—

“PEEVES!” Filch roared gleefully. “You’ve been stealing!”

He ripped back the tapestry below, and Harry saw his horrible, pouchy face and bulging, pale eyes staring up the dark and (to Filch) deserted staircase.

“Hiding, are you?” he said softly. “I’m coming to get you, Peeves . . . You’ve gone and stolen a Triwizard clue, Peeves . . . Dumbledore’ll have you out of here for this, you filthy, pilfering poltergeist . . . ”
