Harry seized Griphook’s fingers and pulled. The blistered goblin emerged by degrees, howling.
“Liberatocorpus!” yelled Harry, and with a crash he and Griphook landed on the surface of the swelling treasure, and the sword flew out of Harry’s hand.
“Get it!” Harry yelled, fighting the pain of the hot metal on his skin, as Griphook clambered onto his shoulders again, determined to avoid the swelling mass of red-hot objects. “Where’s the sword? It had the cup on it!”
The clanking on the other side of the door was growing deafening—it was too late—
“There!”
It was Griphook who had seen it and Griphook who lunged, and in that instant Harry knew that the goblin had never expected them to keep their word. One hand holding tightly to a fistful of Harry’s hair, to make sure he did not fall into the heaving sea of burning gold, Griphook seized the hilt of the sword and swung it high out of Harry’s reach. The tiny golden cup, skewered by the handle on the sword’s blade was flung into the air. The goblin astride him, Harry dived and caught it, and although he could feel it scalding his flesh he did not relinquish it, even while countless Hufflepuff cups burst from his fist, raining down upon him as the entrance of the vault opened up again and he found himself sliding uncontrollably on an expanding avalanche of fiery gold and silver that bore him, Ron, Hermione into the outer chamber.
Hardly aware of the pain from the burns covering his body, and still borne along the swell of replicating treasure, Harry shoved the cup into his pocket and reached up to retrieve the sword, but Griphook was gone. Sliding from Harry’s shoulders the moment he could, he had sprinted for cover amongst the surrounding goblins, brandishing the sword and crying, “Thieves! Thieves! Help! Thieves!” He vanished into the midst of the advancing crowd, all of whom were holding daggers and who accepted him without question.
Slipping on the hot metal, Harry struggled to his feet and knew that the only way out was through.
“Stupefy!” he bellowed, and Ron and Hermione joined in: Jets of red light flew into the crowd of goblins, and some toppled over, but others advanced, and Harry saw several wizard guards running around the corner.
The tethered dragon let out a roar, and a gush of flame flew over the goblins; The wizards fled, doubled-up, back the way they had come, and inspiration, or madness, came to Harry. Pointing his wand at the thick cuffs chaining the beast to the floor, he yelled, “Relashio!”
