“Rosmerta, m’dear, I don’t like them any more than you do,” said Fudge uncomfortably. “Necessary precaution . . . unfortunate, but there you are. . . . I’ve just met some of them. They’re in a fury against Dumbledore—he won’t let them inside the castle grounds.”

“I should think not,” said Professor McGonagall sharply. “How are we supposed to teach with those horrors floating around?”

“Hear, hear!” squeaked tiny Professor Flitwick, whose feet were dangling a foot from the ground.

“All the same,” demurred Fudge, “they are here to protect you all from something much worse. . . . We all know what Black’s capable of. . . . ”

“Do you know, I still have trouble believing it,” said Madam Rosmerta thoughtfully. “Of all the people to go over to the Dark Side, Sirius Black was the last I’d have thought . . . I mean, I remember him when he was a boy at Hogwarts. If you’d told me then what he was going to become, I’d have said you’d had too much mead.”

“You don’t know the half of it, Rosmerta,” said Fudge gruffly. “The worst he did isn’t widely known.”

“The worst?” said Madam Rosmerta, her voice alive with curiosity. “Worse than murdering all those poor people, you mean?”

“I certainly do,” said Fudge.

“I can’t believe that. What could possibly be worse?”

“You say you remember him at Hogwarts, Rosmerta,” murmured Professor McGonagall. “Do you remember who his best friend was?”

“Naturally,” said Madam Rosmerta, with a small laugh. “Never saw one without the other, did you? The number of times I had them in here—ooh, they used to make me laugh. Quite the double act, Sirius Black and James Potter!”

Harry dropped his tankard with a loud clunk. Ron kicked him.

“Precisely,” said Professor McGonagall. “Black and Potter. Ringleaders of their little gang. Both very bright, of course—exceptionally bright, in fact—but I don’t think we’ve ever had such a pair of troublemakers—”

“I dunno,” chuckled Hagrid. “Fred and George Weasley could give ’em a run fer their money.”

“You’d have thought Black and Potter were brothers!” chimed in Professor Flitwick. “Inseparable!”

“Of course they were,” said Fudge. “Potter trusted Black beyond all his other friends. Nothing changed when they left school. Black was best man when James married Lily. Then they named him godfather to Harry. Harry has no idea, of course. You can imagine how the idea would torment him.”

“Because Black turned out to be in league with You-Know-Who?” whispered Madam Rosmerta.
