Ron, Harry, and George kicked, rolled, and pushed the unconscious Malfoy, Crabbe, and Goyle—each of whom looked distinctly the worse for the jumble of jinxes with which they had been hit—out into the corridor, then came back into the compartment and rolled the door shut.

“Exploding Snap, anyone?” said Fred, pulling out a pack of cards.

They were halfway through their fifth game when Harry decided to ask them.

“You going to tell us, then?” he said to George. “Who you were blackmailing?”

“Oh,” said George darkly. “That.”

“It doesn’t matter,” said Fred, shaking his head impatiently. “It wasn’t anything important. Not now, anyway.”

“We’ve given up,” said George, shrugging.

But Harry, Ron, and Hermione kept on asking, and finally, Fred said, “All right, all right, if you really want to know . . . it was Ludo Bagman.”

“Bagman?” said Harry sharply. “Are you saying he was involved in—”

“Nah,” said George gloomily. “Nothing like that. Stupid git. He wouldn’t have the brains.”

“Well, what, then?” said Ron.

Fred hesitated, then said, “You remember that bet we had with him at the Quidditch World Cup? About how Ireland would win, but Krum would get the Snitch?”

“Yeah,” said Harry and Ron slowly.

“Well, the git paid us in leprechaun gold he’d caught from the Irish mascots.”

“So?”

“So,” said Fred impatiently, “it vanished, didn’t it? By next morning, it had gone!”

“But—it must’ve been an accident, mustn’t it?” said Hermione.

George laughed very bitterly.

“Yeah, that’s what we thought, at first. We thought if we just wrote to him, and told him he’d made a mistake, he’d cough up. But nothing doing. Ignored our letter. We kept trying to talk to him about it at Hogwarts, but he was always making some excuse to get away from us.”

“In the end, he turned pretty nasty,” said Fred. “Told us we were too young to gamble, and he wasn’t giving us anything.”

“So we asked for our money back,” said George glowering.

“He didn’t refuse!” gasped Hermione.

“Right in one,” said Fred.

“But that was all your savings!” said Ron.

“Tell me about it,” said George. “’Course, we found out what was going on in the end. Lee Jordan’s dad had had a bit of trouble getting money off Bagman as well. Turns out he’s in big trouble with the goblins. Borrowed loads of gold off them. A gang of them cornered him in the woods after the World Cup and took all the gold he had, and it still wasn’t enough to cover all his debts. They followed him all the way to Hogwarts to keep an eye on him. He’s lost everything gambling. Hasn’t got two Galleons to rub together. And you know how the idiot tried to pay the goblins back?”

“How?” said Harry.
