The wall began to totter, then the top third crumbled into the aisle next door where Ron stood.
“Ron!” Harry bellowed, as somewhere out of sight Hermione screamed, and Harry heard innumerable objects crashing to the floor on the other side of the destabilized wall: He pointed his wand at the rampart, cried, “Finite!” and it steadied.
“No!” shouted Malfoy, staying Crabbe’s arm as the latter made to repeat his spell. “If you wreck the room you might bury this diadem thing!”
“What’s that matter?” said Crabbe, tugging himself free. “It’s Potter the Dark Lord wants, who cares about a die-dum?”
“Potter came in here to get it,” said Malfoy with ill-disguised impatience at the slow-wittedness of his colleagues. “so that must mean—”
“‘Must mean’?” Crabbe turned on Malfoy with undisguised ferocity. “Who cares what you think? I don’t take your orders no more, Draco. You an’ your dad are finished.”
“Harry?” shouted Ron again, from the other side of the junk wad. “What’s going on?”
Harry had lunged for the tiara; Crabbe’s curse missed him but hit the stone bust, which flew into the air; the diadem soared upward and then dropped out of sight in the mass of objects on which the bust had rested.
“STOP!” Malfoy shouted at Crabbe, his voice echoing through the enormous room. “The Dark Lord wants him alive—”
“So? I’m not killing him, am I?” yelled Crabbe, throwing off Malfoy’s restraining arm. “But if I can, I will, the Dark Lord wants him dead anyway, what’s the diff—?”
A jet of scarlet light shot past Harry by inches: Hermione had run around the corner behind him and sent a Stunning Spell straight at Crabbe’s head. It only missed because Malfoy pulled him out of the way.
“It’s that Mudblood! Avada Kedavra!”
Harry saw Hermione dive aside, and his fury that Crabbe had aimed to kill wiped all else from his mind. He shot a Stunning Spell at Crabbe, who lurched out of the way, knocking Malfoy’s wand out of his hand; it rolled out of sight beneath a mountain of broken furniture and bones.
“Don’t kill him! DON’T KILL HIM!” Malfoy yelled at Crabbe and Goyle, who were both aiming at Harry: Their split second’s hesitation was all Harry needed.
“Expelliarmus!”
Goyle’s wand flew out of his hand and disappeared into the bulwark of objects beside him; Goyle leapt foolishly on the spot, trying to retrieve it; Malfoy jumped out of range of Hermione’s second Stunning Spell, and Ron, appearing suddenly at the end of the aisle, shot a full Body-Bind Curse at Crabbe, which narrowly missed.
Crabbe wheeled around and screamed, “Avada Kedavra!” again. Ron leapt out of sight to avoid the jet of green light. The wandless Malfoy cowered behind a three-legged wardrobe as Hermione charged toward them, hitting Goyle with a Stunning Spell as she came.
“It’s somewhere here!” Harry yelled at her, pointing at the pile of junk into which the old tiara had fallen. “Look for it while I go and help R—”
