Harry’s body became instantly rigid and immobile, and he felt himself fall back against the Tower wall, propped like an unsteady statue, unable to move or speak. He could not understand how it had happened—Expelliarmus was not a Freezing Charm—
Then, by the light of the Mark, he saw Dumbledore’s wand flying in an arc over the edge of the ramparts and understood… Dumbledore had wordlessly immobilised Harry, and the second he had taken to perform the spell had cost him the chance of defending himself.
Standing against the ramparts, very white in the face, Dumbledore still showed no sign of panic or distress. He merely looked across at his disarmer and said, “Good evening, Draco.”
Malfoy stepped forwards, glancing around quickly to check that he and Dumbledore were alone. His eyes fell upon the second broom.
“Who else is here?”
“A question I might ask you. Or are you acting alone?”
Harry saw Malfoy’s pale eyes shift back to Dumbledore in the greenish glare of the Mark.
“No,” he said. “I’ve got back-up. There are Death Eaters here in your school tonight.”
“Well, well,” said Dumbledore, as though Malfoy was showing him an ambitious homework project. “Very good indeed. You found a way to let them in, did you?”
“Yeah,” said Malfoy, who was panting. “Right under your nose and you never realised!”
“Ingenious,” said Dumbledore. “Yet… forgive me… where are they now? You seem unsupported.”
“They met some of your guard. They’re having a fight down below. They won’t be long… I came on ahead. I—I’ve got a job to do.”
“Well, then, you must get on and do it, my dear boy,” said Dumbledore softly.
There was silence. Harry stood imprisoned within his own invisible, paralysed body, staring at the two of them, his ears straining to hear sounds of the Death Eaters’ distant fight, and in front of him, Draco Malfoy did nothing but stare at Albus Dumbledore who, incredibly, smiled.
“Draco, Draco, you are not a killer.”
“How do you know?” said Malfoy at once.
He seemed to realise how childish the words had sounded; Harry saw him flush in the Mark’s greenish light.
“You don’t know what I’m capable of,” said Malfoy more forcefully, “you don’t know what I’ve done!”
“Oh, yes, I do,” said Dumbledore mildly. “You almost killed Katie Bell and Ronald Weasley. You have been trying, with increasing desperation, to kill me all year. Forgive me, Draco, but they have been feeble attempts… so feeble, to be honest, that I wonder whether your heart has been really in it…”
“It has been in it!” said Malfoy vehemently. “I’ve been working on it all year, and tonight—”
Somewhere in the depths of the castle below Harry heard a muffled yell. Malfoy stiffened and glanced over his shoulder.
“Somebody is putting up a good fight,” said Dumbledore conversationally. “But you were saying… yes, you have managed to introduce Death Eaters into my school which, I admit, I thought impossible… how did you do it?”
But Malfoy said nothing: he was still listening to whatever was happening below and seemed almost as paralysed as Harry was.
“Perhaps you ought to get on with the job alone,” suggested Dumbledore. “What if your back-up has been thwarted by my guard? As you have perhaps realised, there are members of the Order of the Phoenix here tonight, too. And after all, you don’t really need help… I have no wand at the moment… I cannot defend myself.”
Malfoy merely stared at him.
“I see,” said Dumbledore kindly, when Malfoy neither moved nor spoke. “You are afraid to act until they join you.”
“I’m not afraid!” snarled Malfoy, though he still made no move to hurt Dumbledore. “It’s you who should be scared!”
“But why? I don’t think you will kill me, Draco. Killing is not nearly as easy as the innocent believe… so tell me, while we wait for your friends… how did you smuggle them in here? It seems to have taken you a long time to work out how to do it.”
Malfoy looked as though he was fighting down the urge to shout, or to vomit. He gulped and took several deep breaths, glaring at Dumbledore, his wand pointing directly at the latter’s heart. Then, as though he could not help himself, he said, “I had to mend that broken Vanishing Cabinet that no one’s used for years. The one Montague got lost in last year.”
“Aaaah.”
Dumbledore’s sigh was half a groan. He closed his eyes for a moment.
“That was clever… there is a pair, I take it?”
“The other’s in Borgin and Burkes,” said Malfoy, “and they make a kind of passage between them. Montague told me that when he was stuck in the Hogwarts one, he was trapped in limbo but sometimes he could hear what was going on at school, and sometimes what was going on in the shop, as if the Cabinet was travelling between them, but he couldn’t make anyone hear him… in the end he managed to Apparate out, even though he’d never passed his test. He nearly died doing it. Everyone thought it was a really good story, but I was the only one who realised what it meant—even Borgin didn’t know—I was the one who realised there could be a way into Hogwarts through the Cabinets if I fixed the broken one.”
“Very good,” murmured Dumbledore. “So the Death Eaters were able to pass from Borgin and Burkes into the school to help you… a clever plan, a very clever plan… and, as you say, right under my nose…”
“Yeah,” said Malfoy who, bizarrely, seemed to draw courage and comfort from Dumbledore’s praise. “Yeah, it was!”
“But there were times,” Dumbledore went on, “weren’t there, when you were not sure you would succeed in mending the Cabinet? And you resorted to crude and badly judged measures such as sending me a cursed necklace that was bound to reach the wrong hands… poisoning mead there was only the slightest chance I might drink…”
“Yeah, well, you still didn’t realise who was behind that stuff, did you?” sneered Malfoy, as Dumbledore slid a little down the ramparts, the strength in his legs apparently fading, and Harry struggled fruitlessly, mutely, against the enchantment binding him.
“As a matter of fact, I did,” said Dumbledore. “I was sure it was you.”
“Why didn’t you stop me, then?” Malfoy demanded.
“I tried, Draco. Professor Snape has been keeping watch over you on my orders—”
“He hasn’t been doing your orders, he promised my mother—”
“Of course that is what he would tell you, Draco, but—”
“He’s a double-agent, you stupid old man, he isn’t working for you, you just think he is!”
“We must agree to differ on that, Draco. It so happens that I trust Professor Snape—”
“Well, you’re losing your grip, then!” sneered Malfoy. “He’s been offering me plenty of help—wanting all the glory for himself—wanting a bit of the action—‘What are you doing? Did you do the necklace, that was stupid, it could have blown everything—’ But I haven’t told him what I’ve been doing in the Room of Requirement, he’s going to wake up tomorrow and it’ll all be over and he won’t be the Dark Lord’s favourite any more, he’ll be nothing compared to me, nothing!”
“Very gratifying,” said Dumbledore mildly. “We all like appreciation for our own hard work, of course… but you must have had an accomplice, all the same… someone in Hogsmeade, someone who was able to slip Katie the—the—aaaah—”
Dumbledore closed his eyes again and nodded, as though he was about to fall asleep.
“…of course… Rosmerta. How long has she been under the Imperius Curse?”
“Got there at last, have you?” Malfoy taunted.
