"Sorry," said Harry hastily. "Sorry, I -- I forgot --"

"Forgot!" said Stan weakly. "Blimey, my 'eart's goin' that fast ..."

"So -- so Black was a supporter of You-Know-Who?" Harry prompted apologetically.

"Yeah," said Stan, still rubbing his chest. "Yeah, that's right. Very close to You-Know-'Oo, they say. Anyway, when little 'Arry Potter got the better of You-Know-'Oo --"

Harry nervously flattened his bangs down again.

"-- all You-Know-'Oo's supporters was tracked down, wasn't they, Ern? Most of 'em knew it was all over, wiv You-Know-'Oo gone, and they came quiet. But not Sirius Black. I 'eard he thought 'e'd be second-in-command once You-Know-'Oo 'ad taken over.

"Anyway, they cornered Black in the middle of a street full of Muggles an' Black took out 'is wand and 'e blasted 'alf the street apart, an' a wizard got it, an' so did a dozen Muggles what got in the way. 'Orrible, eh? An' you know what Black did then?" Stan continued in a dramatic whisper.

"What?" said Harry.

"Laughed," said Stan. "Jus' stood there an' laughed. An' when reinforcements from the Ministry of Magic got there, I 'e went wiv em quiet as anyfink, still laughing 'is 'ead off. 'Cos 'e's mad, inee, Ern? Inee mad?"

"If he weren't when he went to Azkaban, he will be now," said Ern in his slow voice. "I'd blow meself up before I set foot in that place. Serves him right, mind you ... after what he did...."

"They 'ad a job coverin' it up, din' they, Ern?" Stan said. "'Ole street blown up an' all them Muggles dead. What was it they said ad 'appened, Ern?"
