J. Rowling - Harry Potter and the Deathly Hallows

“Percy!” Harry saw tear tracks streaking the grime coating Ron’s face as he seized his elder brother’s shoulders and pulled, but Percy would not budge. “Percy, you can’t do anything for him! We’re going to—”

Hermione screamed, and Harry, turning, did not need to ask why. A monstrous spider the size of a small car was trying to climb through the huge hole in the wall. One of Aragog’s descendants had joined the fight.

Ron and Harry shouted together; their spells collided and the monster was blown backward, its legs jerking horribly, and vanished into the darkness.

“It brought friends!” Harry called to the others, glancing over the edge of the castle through the hole in the wall the curses had blasted. More giant spiders were climbing the side of the building, liberated from the Forbidden Forest, into which the Death Eaters must have penetrated. Harry fired Stunning Spells down upon them, knocking the lead monster into its fellows, so that they rolled back down the building and out of sight. Then more curses came soaring over Harry’s head, so close he felt the force of them blow his hair.

“Let’s move, NOW!”

Pushing Hermione ahead of him with Ron, Harry stooped to seize Fred’s body under the armpit. Percy, realizing what Harry was trying to do, stopped clinging to the body and helped: together, crouching low to avoid the curses flying at them from the grounds, they hauled Fred out of the way.

“Here,” said Harry, and they placed him in a niche where a suit of armor had stood earlier. He could not bear to look at Fred a second longer than he had to, and after making sure that the body was well-hidden, he took off after Ron and Hermione. Malfoy and Goyle had vanished but at the end of the corridor, which was now full of dust and falling masonry, glass long gone from windows, he saw many people running backward and forward, whether friends or foes he could not tell. Rounding the corner, Percy let out a bull-like roar: “ROOKWOOD!” and sprinted off in the direction of a tall man, who was pursuing a couple of students. “Harry, in here!” Hermione screamed.

She had pulled Ron behind a tapestry. They seemed to be wrestling together, and for one mad second Harry thought that they were embracing again; then he saw that Hermione was trying to restrain Ron, to stop him running after Percy.

“Listen to me—LISTEN, RON!”

“I wanna help—I wanna kill Death Eaters—”

His face was contorted, smeared with dust and smoke, and he was shaking with rage and grief.

“Ron, we’re the only ones who can end it! Please—Ron—we need the snake, we’ve got to kill the snake!” said Hermione.

But Harry knew how Ron felt: Pursuing another Horcrux could not bring the satisfaction of revenge; he too wanted to fight, to punish them, the people who had killed Fred, and he wanted to find the other Weasleys, and above all make sure, make quite sure, that Ginny was not—but he could not permit that idea to form in his mind—

“We will fight!” Hermione said. “We’ll have to, to reach the snake! But let’s not lose sight now of what we’re supposed to be d-doing! We’re the only ones who can end it!”

She was crying too, and she wiped her face on her torn and singed sleeve as she spoke, but she took great heaving breaths to calm herself as, still keeping a tight hold on Ron, she turned to Harry. “You need to find out where Voldemort is, because he’ll have the snake with him, won’t he? Do it, Harry—look inside him!”

Why was it so easy? Because his scar had been burning for hours, yearning to show him Voldemort’s thoughts? He closed his eyes on her command, and at once, the screams and bangs and all the discordant sounds of the battle were drowned until they became distant, as though he stood far, far away from them…

He was standing in the middle of a desolate but strangely familiar room, with peeling paper on the walls and all the windows boarded up except for one. The sounds of the assault on the castle were muffled and distant. The single unblocked window revealed distant bursts of light where the castle stood, but inside the room was dark except for a solitary oil lamp. He was rolling his wand between his fingers, watching it, his thoughts on the room in the castle, the secret room only he had ever found, the room, like the chamber, that you had to be clever and cunning and inquisitive to discover… He was confident that the boy would not find the diadem… although Dumbledore’s puppet had come much farther than he ever expected… too far…

“My Lord,” said a voice, desperate and cracked. He turned: there was Lucius Malfoy sitting in the darkest corner, ragged and still bearing the marks of the punishment he had received after the boy’s last escape. One of his eyes remained closed and puffy. “My Lord… please… my son…”

“If your son is dead, Lucius, it is not my fault. He did not come and join me, like the rest of the Slytherins. Perhaps he has decided to befriend Harry Potter?”

“No—never,” whispered Malfoy. “You must hope not.”

“Aren’t—aren’t you afraid, my Lord, that Potter might die at another hand but yours?” asked Malfoy, his voice shaking. “Wouldn’t it be… forgive me… more prudent to call off this battle, enter the castle, and seek him y-yourself?”

“Do not pretend, Lucius. You wish the battle to cease so that you can discover what has happened to your son. And I do not need to seek Potter. Before the night is out, Potter will have come to find me.”

Voldemort dropped his gaze once more to the wand in his fingers. It troubled him… and those things that troubled Lord Voldemort needed to be rearranged…

“Go and fetch Snape.”

“Snape, m-my Lord?”

“Snape. Now. I need him. There is a—service—I require from him. Go.”

Frightened, stumbling a little through the gloom, Lucius left the room. Vodlemort continued to stand there, twirling the wand between his fingers, staring at it.

“It is the only way, Nagini,” he whispered, and he looked around, and there was the great thick snake, now suspended in midair, twisting gracefully within the enchanted, protected space he had made for her, a starry, transparent sphere somewhere between a glittering cage and a tank.

With a gasp, Harry pulled back and opened his eyes at the same moment his ears were assaulted with the screeches and cries, the smashes and bangs of battle.

“He’s in the Shrieking Shack. The snake’s with him, it’s got some sort of magical protection around it. He’s just sent Lucius Malfoy to find Snape.”

“Voldemort’s sitting in the Shrieking Shack?” said Hermione, outraged. “He’s not—he’s not even FIGHTING?”

“He doesn’t think he needs to fight,” said Harry. “He thinks I’m going to go to him.”

“But why?”

“He knows I’m after Horcruxes—he’s keeping Nagini close beside him—obviously I’m going to have to go to him to get near the thing—”

“Right,” said Ron, squaring his shoulders. “So you can’t go, that’s what he wants, what he’s expecting. You stay here and look after Hermione, and I’ll go and get it—”

Harry cut across Ron.

“You two stay here, I’ll go under the Cloak and I’ll be back as soon as I—”

“No,” said Hermione, “it makes much more sense if I take the Cloak and—”

“Don’t even think about it,” Ron snarled at her.

Before Hermione could get farther than “Ron, I’m just as capable—” the tapestry at the top of the staircase on which they stood was ripped open.

“POTTER!”

Two masked Death Eaters stood there, but even before their wands were fully raised, Hermione shouted “Glisseo!”

The stairs beneath their feet flattened into a chute and she, Harry, and Ron hurtled down it, unable to control their speed but so fast that the Death Eaters’ Stunning Spells flew far over their heads. They shot through the concealing tapestry at the bottom and spun onto the floor, hitting the opposite wall.
