“She didn’t run amok!” shouted Hermione. “She just picked it up off the ground!”

“Look, can someone just explain what that skull thing was?” said Ron impatiently. “It wasn’t hurting anyone . . . Why’s it such a big deal?”

“I told you, it’s You-Know-Who’s symbol, Ron,” said Hermione, before anyone else could answer. “I read about it in The Rise and Fall of the Dark Arts.”

“And it hasn’t been seen for thirteen years,” said Mr. Weasley quietly. “Of course people panicked . . . it was almost like seeing You-Know-Who back again.”

“I don’t get it,” said Ron, frowning. “I mean . . . it’s still only a shape in the sky . . . ”

“Ron, You-Know-Who and his followers sent the Dark Mark into the air whenever they killed,” said Mr. Weasley. “The terror it inspired . . . you have no idea, you’re too young. Just picture coming home and finding the Dark Mark hovering over your house, and knowing what you’re about to find inside . . . ” Mr. Weasley winced. “Everyone’s worst fear . . . the very worst . . . ”

There was silence for a moment. Then Bill, removing the sheet from his arm to check on his cut, said, “Well, it didn’t help us tonight, whoever conjured it. It scared the Death Eaters away the moment they saw it. They all Disapparated before we’d got near enough to unmask any of them. We caught the Robertses before they hit the ground, though. They’re having their memories modified right now.”

“Death Eaters?” said Harry. “What are Death Eaters?”

“It’s what You-Know-Who’s supporters called themselves,” said Bill. “I think we saw what’s left of them tonight—the ones who managed to keep themselves out of Azkaban, anyway.”

“We can’t prove it was them, Bill,” said Mr. Weasley. “Though it probably was,” he added hopelessly.

“Yeah, I bet it was!” said Ron suddenly. “Dad, we met Draco Malfoy in the woods, and he as good as told us his dad was one of those nutters in masks! And we all know the Malfoys were right in with You-Know-Who!”

“But what were Voldemort’s supporters—” Harry began. Everybody flinched—like most of the wizarding world, the Weasleys always avoided saying Voldemort’s name. “Sorry,” said Harry quickly. “What were You-Know-Who’s supporters up to, levitating Muggles? I mean, what was the point?”

“The point?” said Mr. Weasley with a hollow laugh. “Harry, that’s their idea of fun. Half the Muggle killings back when You-Know-Who was in power were done for fun. I suppose they had a few drinks tonight and couldn’t resist reminding us all that lots of them are still at large. A nice little reunion for them,” he finished disgustedly.

“But if they were the Death Eaters, why did they Disapparate when they saw the Dark Mark?” said Ron. “They’d have been pleased to see it, wouldn’t they?”
