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.
But even as he shouted, another jet of green light flew at Dumbledore from Voldemort’s wand and the snake struck—
Fawkes swooped down in front of Dumbledore, opened his beak wide and swallowed the jet of green light whole: he burst into flame and fell to the floor, small, wrinkled and flightless. At the same moment, Dumbledore brandished his wand in one long, fluid movement—the snake, which had been an instant from sinking its fangs into him, flew high into the air and vanished in a wisp of dark smoke; and the water in the pool rose up and covered Voldemort like a cocoon of molten glass.
For a few seconds Voldemort was visible only as a dark, rippling, faceless figure, shimmering and indistinct upon the plinth, clearly struggling to throw off the suffocating mass.

“MASTER!” screamed Bellatrix.
Sure it was over, sure Voldemort had decided to flee, Harry made to run out from behind his statue guard, but Dumbledore bellowed: “Stay where you are, Harry!”
For the first time, Dumbledore sounded frightened. Harry could not see why: the hall was quite empty but for themselves, the sobbing Bellatrix still trapped under the witch statue, and the baby phoenix Fawkes croaking feebly on the floor—

He was gone from the hall, he was locked in the coils of a creature with red eyes, so tightly bound that Harry did not know where his body ended and the creature’s began: they were fused together, bound by pain, and there was no escape—
