“Fleur didn’t turn up, I couldn’t leave her,” Harry panted.

“Harry, you prat,” said Ron, “you didn’t take that song thing seriously, did you? Dumbledore wouldn’t have let any of us drown!”

“The song said—”

“It was only to make sure you got back inside the time limit!” said Ron. “I hope you didn’t waste time down there acting the hero!”

Harry felt both stupid and annoyed. It was all very well for Ron; he’d been asleep, he hadn’t felt how eerie it was down in the lake, surrounded by spear-carrying merpeople who’d looked more than capable of murder.

“C’mon,” Harry said shortly, “help me with her, I don’t think she can swim very well.”

They pulled Fleur’s sister through the water, back toward the bank where the judges stood watching, twenty merpeople accompanying them like a guard of honor, singing their horrible screechy songs.

Harry could see Madam Pomfrey fussing over Hermione, Krum, Cedric, and Cho, all of whom were wrapped in thick blankets. Dumbledore and Ludo Bagman stood beaming at Harry and Ron from the bank as they swam nearer, but Percy, who looked very white and somehow much younger than usual, came splashing out to meet them. Meanwhile Madame Maxime was trying to restrain Fleur Delacour, who was quite hysterical, fighting tooth and nail to return to the water.

“Gabrielle! Gabrielle! Is she alive? Is she ’urt?”

“She’s fine!” Harry tried to tell her, but he was so exhausted he could hardly talk, let alone shout.

Percy seized Ron and was dragging him back to the bank (“Gerroff, Percy, I’m all right!”); Dumbledore and Bagman were pulling Harry upright; Fleur had broken free of Madame Maxime and was hugging her sister.

“It was ze grindylows . . . zey attacked me . . . oh Gabrielle, I thought . . . I thought . . . ”

“Come here, you,” said Madam Pomfrey. She seized Harry and pulled him over to Hermione and the others, wrapped him so tightly in a blanket that he felt as though he were in a straitjacket, and forced a measure of very hot potion down his throat. Steam gushed out of his ears.

“Harry, well done!” Hermione cried. “You did it, you found out how all by yourself!”

“Well—” said Harry. He would have told her about Dobby, but he had just noticed Karkaroff watching him. He was the only judge who had not left the table; the only judge not showing signs of pleasure and relief that Harry, Ron, and Fleur’s sister had got back safely. “Yeah, that’s right,” said Harry, raising his voice slightly so that Karkaroff could hear him.
