A white pawn had moved forward two squares.
Ron started to direct the black pieces. They moved silently wherever he sent them. Harry’s knees were trembling. What if they lost?
“Harry—move diagonally four squares to the right.”
Their first real shock came when their other knight was taken. The white queen smashed him to the floor and dragged him off the board, where he lay quite still, facedown.
“Had to let that happen,” said Ron, looking shaken. “Leaves you free to take that bishop, Hermione, go on.”
Every time one of their men was lost, the white pieces showed no mercy. Soon there was a huddle of limp black players slumped along the wall. Twice, Ron only just noticed in time that Harry and Hermione were in danger. He himself darted around the board, taking almost as many white pieces as they had lost black ones.
“We’re nearly there,” he muttered suddenly. “Let me think—let me think…”
The white queen turned her blank face toward him.
“Yes…” said Ron softly, “It’s the only way… I’ve got to be taken.”
“NO!” Harry and Hermione shouted.
“That’s chess!” snapped Ron. “You’ve got to make some sacrifices! I take one step forward and she’ll take me—that leaves you free to checkmate the king, Harry!”
“But—”
“Do you want to stop Snape or not?”
“Ron—”
“Look, if you don’t hurry up, he’ll already have the Stone!”
There was no alternative.
“Ready?” Ron called, his face pale but determined. “Here I go—now, don’t hang around once you’ve won.”
He stepped forward, and the white queen pounced. She struck Ron hard across the head with her stone arm, and he crashed to the floor—Hermione screamed but stayed on her square—the white queen dragged Ron to one side. He looked as if he’d been knocked out.
Shaking, Harry moved three spaces to the left.
The white king took off his crown and threw it at Harry’s feet. They had won. The chessmen parted and bowed, leaving the door ahead clear. With one last desperate look back at Ron, Harry and Hermione charged through the door and up the next passageway.
“What if he’s—?”
“He’ll be all right,” said Harry, trying to convince himself. “What do you reckon’s next?”
“We’ve had Sprout’s, that was the Devil’s Snare; Flitwick must’ve put charms on the keys; McGonagall transfigured the chessmen to make them alive; that leaves Quirrell’s spell, and Snape’s.”
They had reached another door.
“All right?” Harry whispered.
“Go on.”
Harry pushed it open.
A disgusting smell filled their nostrils, making both of them pull their robes up over their noses. Eyes watering, they saw, flat on the floor in front of them, a troll even larger than the one they had tackled, out cold with a bloody lump on its head.
“I’m glad we didn’t have to fight that one,” Harry whispered as they stepped carefully over one of its massive legs. “Come on, I can’t breathe.”
He pulled open the next door, both of them hardly daring to look at what came next—but there was nothing very frightening in here, just a table with seven differently shaped bottles standing on it in a line.
“Snape’s,” said Harry. “What do we have to do?”
They stepped over the threshold, and immediately a fire sprang up behind them in the doorway. It wasn’t ordinary fire either; it was purple. At the same instant, black flames shot up in the doorway leading onward. They were trapped.
“Look!” Hermione seized a roll of paper lying next to the bottles. Harry looked over her shoulder to read it:
Hermione let out a great sigh and Harry, amazed, saw that she was smiling, the very last thing he felt like doing.
“Brilliant,” said Hermione. “This isn’t magic—it’s logic—a puzzle. A lot of the greatest wizards haven’t got an ounce of logic, they’d be stuck in here forever.”
“But so will we, won’t we?”
“Of course not,” said Hermione. “Everything we need is here on this paper. Seven bottles: three are poison; two are wine; one will get us safely through the black fire, and one will get us back through the purple.”
“But how do we know which to drink?”
“Give me a minute.”
Hermione read the paper several times. Then she walked up and down the line of bottles, muttering to herself and pointing at them. At last, she clapped her hands.
“Got it,” she said. “The smallest bottle will get us through the black fire—toward the Stone.”
Harry looked at the tiny bottle.
“There’s only enough there for one of us,” he said. “That’s hardly one swallow.”
They looked at each other.
“Which one will get you back through the purple flames?”
Hermione pointed at a rounded bottle at the right end of the line.
“You drink that,” said Harry. “No, listen, get back and get Ron. Grab brooms from the flying-key room, they’ll get you out of the trapdoor and past Fluffy—go straight to the owlery and send Hedwig to Dumbledore, we need him. I might be able to hold Snape off for a while, but I’m no match for him, really.”
“But Harry—what if You-Know-Who’s with him?”
“Well—I was lucky once, wasn’t I?” said Harry, pointing at his scar. “I might get lucky again.”
Hermione’s lip trembled, and she suddenly dashed at Harry and threw her arms around him.
“Hermione!”
“Harry—you’re a great wizard, you know.”
“I’m not as good as you,” said Harry, very embarrassed, as she let go of him.
“Me!” said Hermione. “Books! And cleverness! There are more important things—friendship and bravery and—oh Harry—be careful!”
“You drink first,” said Harry. “You are sure which is which, aren’t you?”
“Positive,” said Hermione. She took a long drink from the round bottle at the end, and shuddered.
“It’s not poison?” said Harry anxiously.
“No—but it’s like ice.”
“Quick, go, before it wears off.”
“Good luck—take care.”
“GO!”
Hermione turned and walked straight through the purple fire.
Harry took a deep breath and picked up the smallest bottle. He turned to face the black flames.
“Here I come,” he said, and he drained the little bottle in one gulp.
It was indeed as though ice was flooding his body. He put the bottle down and walked forward; he braced himself, saw the black flames licking his body, but couldn’t feel them—for a moment he could see nothing but dark fire—then he was on the other side, in the last chamber.
There was already someone there—but it wasn’t Snape. It wasn’t even Voldemort.
17. THE MAN WITH TWO FACES
It was Quirrell.
“You!” gasped Harry.
Quirrell smiled. His face wasn’t twitching at all.
“Me,” he said calmly. “I wondered whether I’d be meeting you here, Potter.”
“But I thought—Snape—”
