They marched in silence around a corner and she stopped before a large and extremely ugly stone gargoyle.
“Lemon drop!” she said. This was evidently a password, because the gargoyle sprang suddenly to life and hopped aside as the wall behind him split in two. Even full of dread for what was coming, Harry couldn’t fail to be amazed. Behind the wall was a spiral staircase that was moving smoothly upward, like an escalator. As he and Professor McGonagall stepped onto it, Harry heard the wall thud closed behind them. They rose upward in circles, higher and higher, until at last, slightly dizzy, Harry saw a gleaming oak door ahead, with a brass knocker in the shape of a griffin.
He knew now where he was being taken. This must be where Dumbledore lived.
THE POLYJUICE POTION
They stepped off the stone staircase at the top, and Professor McGonagall rapped on the door. It opened silently and they entered. Professor McGonagall told Harry to wait and left him there, alone.
Harry looked around. One thing was certain: of all the teachers’ offices Harry had visited so far this year, Dumbledore’s was by far the most interesting. If he hadn’t been scared out of his wits that he was about to be thrown out of school, he would have been very pleased to have a chance to look around it.
It was a large and beautiful circular room, full of funny little noises. A number of curious silver instruments stood on spindle legged tables, whirring and emitting little puffs of smoke. The walls were covered with portraits of old headmasters and headmistresses, all of whom were snoozing gently in their frames. There was also an enormous, claw footed desk, and, sitting on a shelf behind it, a shabby, tattered wizard’s hat—the Sorting Hat.
Harry hesitated. He cast a wary eye around the sleeping witches and wizards on the walls. Surely it couldn’t hurt if he took the hat down and tried it on again? Just to see… just to make sure it had put him in the right House—
He walked quietly around the desk, lifted the hat from its shelf, and lowered it slowly onto his head. It was much too large and slipped down over his eyes, just as it had done the last time he’d put it on. Harry stared at the black inside of the hat, waiting. Then a small voice said in his ear, “Bee in your bonnet, Harry Potter?”
“Er, yes,” Harry muttered. “Er—sorry to bother you—I wanted to ask—”
“You’ve been wondering whether I put you in the right House,” said the hat smartly. “Yes… you were particularly difficult to place. But I stand by what I said before”—Harry’s heart leapt—“you would have done well in Slytherin—”
