Harry looked back at the snake, willing himself to believe it was alive. If he moved his head, the candlelight made it look as though it were moving.
“Open up,” he said.
Except that the words weren’t what he heard; a strange hissing had escaped him, and at once the tap glowed with a brilliant white light and began to spin. Next second, the sink began to move; the sink, in fact, sank, right out of sight, leaving a large pipe exposed, a pipe wide enough for a man to slide into.
Harry heard Ron gasp and looked up again. He had made up his mind what he was going to do.
“I’m going down there,” he said.
He couldn’t not go, not now they had found the entrance to the Chamber, not if there was even the faintest, slimmest, wildest chance that Ginny might be alive.
“Me too,” said Ron.
There was a pause.
“Well, you hardly seem to need me,” said Lockhart, with a shadow of his old smile. “I’ll just—”
He put his hand on the door knob, but Ron and Harry both pointed their wands at him.
“You can go first,” Ron snarled.
White faced and wandless, Lockhart approached the opening.
“Boys,” he said, his voice feeble. “Boys, what good will it do?”
Harry jabbed him in the back with his wand. Lockhart slid his legs into the pipe.
“I really don’t think—” he started to say, but Ron gave him a push, and he slid out of sight. Harry followed quickly. He lowered himself slowly into the pipe, then let go.
It was like rushing down an endless, slimy, dark slide. He could see more pipes branching off in all directions, but none as large as theirs, which twisted and turned, sloping steeply downward, and he knew that he was falling deeper below the school than even the dungeons. Behind him he could hear Ron, thudding slightly at the curves.
And then, just as he had begun to worry about what would happen when he hit the ground, the pipe leveled out, and he shot out of the end with a wet thud, landing on the damp floor of a dark stone tunnel large enough to stand in. Lockhart was getting to his feet a little ways away, covered in slime and white as a ghost. Harry stood aside as Ron came whizzing out of the pipe, too.
“We must be miles under the school,” said Harry, his voice echoing in the black tunnel.
“Under the lake, probably,” said Ron, squinting around at the dark, slimy walls.
All three of them turned to stare into the darkness ahead.
“Lumos!” Harry muttered to his wand and it lit again. “C’mon,” he said to Ron and Lockhart, and off they went, their footsteps slapping loudly on the wet floor.
