“Don’t tell me it was a mistake, sir, he was listening at the door!”
“Please let me finish.” Dumbledore waited until Harry had nodded curtly, then went on. “Professor Snape made a terrible mistake. He was still in Lord Voldemort’s employ on the night he heard the first half of Professor Trelawney’s prophecy. Naturally, he hastened to tell his master what he had heard, for it concerned his master most deeply. But he did not know—he had no possible way of knowing—which boy Voldemort would hunt from then onwards, or that the parents he would destroy in his murderous quest were people that Professor Snape knew, that they were your mother and father—”
Harry let out a yell of mirthless laughter.
“He hated my dad like he hated Sirius! Haven’t you noticed, Professor, how the people Snape hates tend to end up dead?”
“You have no idea of the remorse Professor Snape felt when he realised how Lord Voldemort had interpreted the prophecy, Harry. I believe it to be the greatest regret of his life and the reason that he returned—”
“But he’s a very good Occlumens, isn’t he, sir?” said Harry, whose voice was shaking with the effort of keeping it steady. “And isn’t Voldemort convinced that Snape’s on his side, even now? Professor… how can you be sure Snape’s on our side?”
Dumbledore did not speak for a moment; he looked as though he was trying to make up his mind about something. At last he said, “I am sure. I trust Severus Snape completely.”
Harry breathed deeply for a few moments in an effort to steady himself. It did not work.
“Well, I don’t!” he said, as loudly as before. “He’s up to something with Draco Malfoy right now, right under your nose, and you still—”
“We have discussed this, Harry,” said Dumbledore, and now he sounded stern again. “I have told you my views.”
“You’re leaving the school tonight and I’ll bet you haven’t even considered that Snape and Malfoy might decide to—”
“To what?” asked Dumbledore, his eyebrows raised. “What is it that you suspect them of doing, precisely?”
“I… they’re up to something!” said Harry and his hands curled into fists as he said it. “Professor Trelawney was just in the Room of Requirement, trying to hide her sherry bottles, and she heard Malfoy whooping, celebrating! He’s trying to mend something dangerous in there and if you ask me he’s fixed it at last and you’re about to just walk out of school without—”
“Enough,” said Dumbledore. He said it quite calmly, and yet Harry fell silent at once; he knew that he had finally crossed some invisible line. “Do you think that I have once left the school unprotected during my absences this year? I have not. Tonight, when I leave, there will again be additional protection in place. Please do not suggest that I do not take the safety of my students seriously, Harry.”
“I didn’t—” mumbled Harry, a little abashed, but Dumbledore cut across him.
“I do not wish to discuss the matter any further.”
Harry bit back his retort, scared that he had gone too far, that he had ruined his chance of accompanying Dumbledore, but Dumbledore went on, “Do you wish to come with me tonight?”
“Yes,” said Harry at once.
“Very well, then listen.”
Dumbledore drew himself up to his full height.
“I take you with me on one condition: that you obey any command I might give you at once, and without question.”
“Of course.”
“Be sure to understand me, Harry. I mean that you must follow even such orders as “run”, “hide” or “go back”. Do I have your word?”
“I—yes, of course.”
“If I tell you to hide, you will do so?”
“Yes.”
“If I tell you to flee, you will obey?”
“Yes.”
“If I tell you to leave me, and save yourself, you will do as I tell you?”
“I—”
“Harry?”
They looked at each other for a moment.
“Yes, sir.”
“Very good. Then I wish you to go and fetch your Cloak and meet me in the Entrance Hall in five minutes’ time.”
Dumbledore turned back to look out of the fiery window; the sun was now a ruby-red glare along the horizon. Harry walked quickly from the office and down the spiral staircase. His mind was oddly clear all of a sudden. He knew what to do.
Ron and Hermione were sitting together in the common room when he came back. “What does Dumbledore want?” Hermione said at once. “Harry, are you OK?” she added anxiously.
“I’m fine,” said Harry shortly, racing past them. He dashed up the stairs and into his dormitory, where he flung open his trunk and pulled out the Marauder’s Map and a pair of balled-up socks. Then he sped back down the stairs and into the common room, skidding to a halt where Ron and Hermione sat, looking stunned.
“I haven’t got much time,” Harry panted, “Dumbledore thinks I’m getting my Invisibility Cloak. Listen…”
Quickly he told them where he was going, and why. He did not pause either for Hermione’s gasps of horror or for Ron’s hasty questions; they could work out the finer details for themselves later.
“…so you see what this means?” Harry finished at a gallop. “Dumbledore won’t be here tonight, so Malfoy’s going to have another clear shot at whatever he’s up to. No, listen to me!” he hissed angrily, as both Ron and Hermione showed every sign of interrupting. “I know it was Malfoy celebrating in the Room of Requirement. Here—” He shoved the Marauder’s Map into Hermione’s hand. “You’ve got to watch him and you’ve got to watch Snape, too. Use anyone else who you can rustle up from the D.A. Hermione, those contact Galleons will still work, right? Dumbledore says he’s put extra protection in the school, but if Snape’s involved, he’ll know what Dumbledore’s protection is, and how to avoid it—but he won’t be expecting you lot to be on the watch, will he?”
“Harry—” began Hermione, her eyes huge with fear.
“I haven’t got time to argue,” said Harry curtly. Take this as well—”
He thrust the socks into Ron’s hands.
“Thanks,” said Ron. “Er—why do I need socks?”
“You need what’s wrapped in them, it’s the Felix Felicis. Share it between yourselves and Ginny too. Say goodbye to her from me. I’d better go, Dumbledore’s waiting—”
“No!” said Hermione, as Ron unwrapped the tiny little bottle of golden potion, looking awestruck. “We don’t want it, you take it, who knows what you’re going to be facing?”
“I’Il be fine, I’ll be with Dumbledore,” said Harry. “I want to know you lot are OK… don’t look like that, Hermione, I’ll see you later—”
And he was off, hurrying back through the portrait hole towards the Entrance Hall.
Dumbledore was waiting beside the oaken front doors. He turned as Harry came skidding out on to the topmost stone step, panting hard, a searing stitch in his side.
“I would like you to wear your Cloak, please,” said Dumbledore, and he waited until Harry had thrown it on before saying, “Very good. Shall we go?”
Dumbledore set off at once down the stone steps, his own travelling cloak barely stirring in the still summer air. Harry hurried alongside him under the Invisibility Cloak, still panting and sweating rather a lot.
“But what will people think when they see you leaving, Professor?” Harry asked, his mind on Malfoy and Snape.
“That I am off into Hogsmeade for a drink,” said Dumbledore lightly. “I sometimes offer Rosmerta my custom, or else visit the Hog’s Head… or I appear to. It is as good a way as any of disguising one’s true destination.”
They made their way down the drive in the gathering twilight. The air was full of the smells of warm grass, lake water and wood smoke from Hagrid’s cabin. It was difficult to believe that they were heading for anything dangerous or frightening.
