‘But Master—he is here—he is below—’

‘But Master—he is here—he is below—’

Voldemort paid no attention.

‘I have nothing more to say to you, Potter,’ he said quietly. ‘You have irked me too often, for too long. AVADA KEDAVRA!’

Harry had not even opened his mouth to resist; his mind was blank, his wand pointing uselessly at the floor.

But the headless golden statue of the wizard in the fountain had sprung alive, leaping from its plinth to land with a crash on the floor between Harry and Voldemort. The spell merely glanced off its chest as the statue flung out its arms to protect Harry.

‘What—?’ cried Voldemort, staring around. And then he breathed, ‘Dumbledore!’

Harry looked behind him, his heart pounding. Dumbledore was standing in front of the golden gates.

Voldemort raised his wand and another jet of green light streaked at Dumbledore, who turned and was gone in a whirling of his cloak. Next second, he had reappeared behind Voldemort and waved his wand towards the remnants of the fountain. The other statues sprang to life. The statue of the witch ran at Bellatrix, who screamed and sent spells streaming uselessly off its chest, before it dived at her, pinning her to the floor. Meanwhile, the goblin and the house-elf scuttled towards the fireplaces set along the wall and the one-armed centaur galloped at Voldemort, who vanished and reappeared beside the pool. The headless statue thrust Harry backwards, away from the fight, as Dumbledore advanced on Voldemort and the golden centaur cantered around them both.

‘It was foolish to come here tonight, Tom,’ said Dumbledore calmly. ‘The Aurors are on their way—’

‘By which time I shall be gone, and you will be dead!’ spat Voldemort. He sent another killing curse at Dumbledore but missed, instead hitting the security guard's desk, which burst into flame.

Dumbledore flicked his own wand: the force of the spell that emanated from it was such that Harry, though shielded by his golden guard, felt his hair stand on end as it passed and this time Voldemort was forced to conjure a shining silver shield out of thin air to deflect it. The spell, whatever it was, caused no visible damage to the shield, though a deep, gong-like note reverberated from it—an oddly chilling sound.

‘You do not seek to kill me, Dumbledore?’ called Voldemort, his scarlet eyes narrowed over the top of the shield. ‘Above such brutality, are you?’

‘We both know that there are other ways of destroying a man, Tom,’ Dumbledore said calmly, continuing to walk towards Voldemort as though he had not a fear in the world, as though nothing had happened to interrupt his stroll up the hall. ‘Merely taking your life would not satisfy me, I admit—’

‘There is nothing worse than death, Dumbledore!’ snarled Voldemort.

‘You are quite wrong,’ said Dumbledore, still closing in upon Voldemort and speaking as lightly as though they were discussing the matter over drinks. Harry felt scared to see him walking along, undefended, shieldless; he wanted to cry out a warning, but his headless guard kept shunting him backwards towards the wall, blocking his every attempt to get out from behind it. ‘Indeed, your failure to understand that there are things much worse than death has always been your greatest weakness—’

Another jet of green light flew from behind the silver shield. This time it was the one-armed centaur, galloping in front of Dumbledore, that took the blast and shattered into a hundred pieces, but before the fragments had even hit the floor, Dumbledore had drawn back his wand and waved it as though brandishing a whip. A long thin flame flew from the tip; it wrapped itself around Voldemort, shield and all. For a moment, it seemed Dumbledore had won, but then the fiery rope became a serpent, which relinquished its hold on Voldemort at once and turned, hissing furiously, to face Dumbledore.

Voldemort vanished; the snake reared from the floor, ready to strike—

There was a burst of flame in midair above Dumbledore just as Voldemort reappeared, standing on the plinth in the middle of the pool where so recently the five statues had stood.

‘Look out!’ Harry yelled.
