Dumbledore scooped the locket from the bottom of the stone basin and stowed it inside his robes. Wordlessly, he gestured to Harry to come to his side. Distracted by the flames, the Inferi seemed unaware that their quarry was leaving as Dumbledore led Harry back to the boat, the ring of fire moving with them, around them, the bewildered Inferi accompanying them to the water’s edge, where they slipped gratefully back into their dark waters.
Harry, who was shaking all over, thought for a moment that Dumbledore might not be able to climb into the boat; he staggered a little as he attempted it; all his efforts seemed to be going into maintaining the ring of protective flame around them. Harry seized him and helped him back to his seat. Once they were both safely jammed inside again, the boat began to move back across the black water, away from the rock, still encircled by that ring of fire, and it seemed that the Inferi swarming below them did not dare resurface.
“Sir,” panted Harry, “sir, I forgot—about fire—they were coming at me and I panicked—”
“Quite understandable,” murmured Dumbledore. Harry was alarmed to hear how faint his voice was.
They reached the bank with a little bump and Harry leapt out, then turned quickly to help Dumbledore. The moment that Dumbledore reached the bank he let his wand hand fall; the ring of fire vanished, but the Inferi did not emerge again from the water. The little boat sank into the water once more; clanking and tinkling, its chain slithered back into the lake too. Dumbledore gave a great sigh and leaned against the cavern wall.
“I am weak…” he said.
“Don’t worry, sir,” said Harry at once, anxious about Dumbledore’s extreme pallor and by his air of exhaustion. “Don’t worry, I’ll get us back… Lean on me, sir…”
And pulling Dumbledore’s uninjured arm around his shoulders, Harry guided his headmaster back around the lake, bearing most of his weight.
“The protection was… after all… well-designed,” said Dumbledore faintly. “One alone could not have done it… You did well, very well, Harry…”
“Don’t talk now,” said Harry, fearing how slurred Dumbledore’s voice had become, how much his feet dragged. “Save your energy, sir… We’ll soon be out of here…”
“The archway will have sealed again… My knife…”
“There’s no need, I got cut on the rock,” said Harry firmly. “Just tell me where…”
“Here…”
Harry wiped his grazed forearm upon the stone: Having received its tribute of blood, the archway reopened instantly. They crossed the outer cave, and Harry helped Dumbledore back into the icy seawater that filled the crevice in the cliff.
“It’s going to be all right, sir,” Harry said over and over again, more worried by Dumbledore’s silence than he had been by his weakened voice. “We’re nearly there… I can Apparate us both back… Don’t worry…”
“I am not worried, Harry,” said Dumbledore, his voice a little stronger despite the freezing water. “I am with you.”
27. THE LIGHTNING-STRUCK TOWER
Once back under the starry sky, Harry heaved Dumbledore on to the top of the nearest boulder and then to his feet. Sodden and shivering, Dumbledore’s weight still upon him, Harry concentrated harder than he had ever done upon his destination: Hogsmeade. Closing his eyes, gripping Dumbledore’s arm as tightly as he could, he stepped forwards into that feeling of horrible compression.
He knew it had worked before he opened his eyes: the smell of salt, the sea breeze had gone. He and Dumbledore were shivering and dripping in the middle of the dark High Street in Hogsmeade. For one horrible moment Harry’s imagination showed him more Inferi creeping towards him around the sides of shops, but he blinked and saw that nothing was stirring; all was still, the darkness complete but for a few streetlamps and lit upper windows.
“We did it, Professor!” Harry whispered with difficulty; he suddenly realised that he had a searing stitch in his chest. “We did it! We got the Horcrux!”
Dumbledore staggered against him. For a moment, Harry thought that his inexpert Apparition had thrown Dumbledore off-balance; then he saw his face, paler and damper than ever in the distant light of a streetlamp.
“Sir, are you all right?”
“I’ve been better,” said Dumbledore weakly, though the corners of his mouth twitched. “That potion… was no health drink…”
And to Harry’s horror, Dumbledore sank on to the ground.
“Sir—it’s OK, sir, you’re going to be all right, don’t worry—”
He looked around desperately for help, but there was nobody to be seen and all he could think was that he must somehow get Dumbledore quickly to the hospital wing.
“We need to get you up to the school, sir… Madam Pomfrey…”
“No,” said Dumbledore. “It is… Professor Snape whom I need… but I do not think… I can walk very far just yet…”
“Right—sir, listen—I’m going to knock on a door, find a place you can stay—then I can run and get Madam—”
“Severus,” said Dumbledore clearly. “I need Severus…”
“All right then, Snape—but I’m going to have to leave you for a moment so I can—”
