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； 〃iFinite！i〃 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； iDracoi。 You an' your dad are finished。〃
〃Harry？〃 shouted Ron again； from the other side of the junk wad。 〃What's going on？〃
〃Harry？〃 mimicked Crabbe。 〃What's going on … ino；i Potter！ iCrucio！i〃
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！ iAvada Kedavra！i〃
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。
〃iExpelliarmus！i〃
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； 〃iAvada Kedavra！i〃 again。 Ron leapt out of sight to avoid the jet of green light。 The wand…less 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 …〃
〃HARRY！〃 she screamed。
A roaring； billowing noise behind him gave him a moment's warning。 He turned and saw both Ron and Crabbe running as hard as they could up the aisle toward them。
〃Like it hot； scum？〃 roared Crabbe as he ran。
But he seemed to have no control over what he had done。 Flames of abnormal size were pursuing them； licking up the sides of the junk bulwarks； which were crumbling to soot at their touch。
〃iAguamenti！i〃 Harry bawled； but the jet of water that soared from the tip of his wand evaporated in the air。
〃RUN！〃
Malfoy grabbed the Stunned Goyle and dragged him along； Crabbe outstripped all of them； now looking terrified； Harry； Ron； and Hermione pelted along in his wake； and the fire pursued them。 It was not normal fire； Crabbe had used a curse of which Harry had no knowledge。 As they turned a corner the flames chased them as though they were alive； sentient； intent upon killing them。 Now the fire was mutating； forming a gigantic pack of
fiery beasts： Flaming serpents； chimaeras； and dragons rose and fell and rose again； and the detritus of centuries on which they were feeding was thrown up into the air into their fanged mouths； tossed high on clawed feet； before being consumed by the inferno。
Malfoy； Crabbe； and Goyle had vanished from view： Harry； Ron and Hermione stopped dead； the fiery monsters were circling them； drawing closer and closer； claws and horns and tails lashed； and the heat was solid as a wall around them。
〃What can we do？〃 Hermione screamed over the deafening roars of the fire。 〃What can we do？〃
〃Here！〃
Harry seized a pair of heavy…looking broomsticks from the nearest pile of junk and threw one to Ron； who pulled Hermione onto it behind him。 Harry swung his leg over the second broom and； with hard kicks to the ground； they soared up in the air； missing by feet the horned beak of a flaming raptor that snapped its jaws at them。 The smoke and heat were being overwhelming： Below them the cursed fire was consuming the contraband of generations of hunted students； the guilty outes of a thousand banned experiments； the secrets of the countless souls who had sought refuge in the room。 Harry couldnot see a trace of Malfoy； Crabbe； or Goyle anywhere。 He swooped as low as he dare over the marauding monsters of flame to try to find them； but there was nothing but fire： What a terrible way to die。 。 。 。 He had never wanted this。 。 。 。
〃Harry； let's get out； let's get out！〃 bellowed Ron； though it was impossible to see where the door was through the black smoke。
And then Harry heard a thin； piteous human scream from amidst the terrible motion； the thunder of devouring flame。
〃It's … too … dangerous … ！〃 Ron yelled； but Harry wheeled in the air。 His glasses giving his eyes some small protection from the smoke； he raked the firestorm below； seeking a sign of life； a limb or a face that was not yet charred like wood。 。 。 。
And he saw them： Malfoy with his arms around the unconscious Goyle； the pair of them perched on a fragile tower of charred desks； and Harry dived。 Malfoy saw him ing and raised one arm； but even as Harry grasped it he knew at once that it was no good。 Goyle was too heavy and Malfoy's hand； covered in sweat； slid instantly out of Harry's …
〃IF WE DIE FOR THEM； I'LL KILL YOU； HARRY！〃 roared Ron's voice； and； as a great flaming chimaera bore down upon them； he and Hermione dragged Goyle onto their broom and rose； rolling and pitching； into the air once more as Malfoy clambered up behind Harry。
〃The door； get to the door； the door！〃 screamed Malfoy in Harry's ear； and Harry sped up； following Ron； Hermione； and Goyle through the billowing black smoke； hardly able to breathe： and all around them the last few objects unburned by the devouring flames were flung into the air； as the creatures of the cursed fire cast them high in celebration： cups and shields； a sparkling necklace； and an old； discolored tiara …
〃iWhat are you doing； what are you doing； the door's that way！i〃 screamed Malfoy； but Harry made a hairpin swerve and dived。 The diadem seemed to fall in slow motion； turning and glittering as it dropped toward the maw of a yawning serpent； and then he had it； caught it around his wrist …
Harry swerved again as
