yarrr, ye scurvy boy-king, halt ye whinin'

Harry was halfway along the passage to the bar, which was now very dark, when he heard another pair of angry voices coming from the parlor. A second later, he recognized them as Mr. and Mrs. Weasleys'. He hesitated, not wanting them to know he'd heard them arguing, when the sound of his own name made him stop, then move closer to the parlor door.

"...makes no sense not to tell him," Mr. Weasley was saying heatedly. "Harry's got a right to know. I've tried to tell Fudge, but he insists on treating Harry like a child. He's thirteen years old and - "

"Arthur, the truth would terrify him!" said Mrs. Weasley shrilly. "Do you really want to send Harry back to school with that hanging over him? For heaven's sake, he's happy not knowing!"

"I don't want to make him miserable, I want to put him on his guard!" retorted Mr. Weasley. "You know what Harry and Ron are like, wandering off by themselves - they've ended up in the Forbidden Forest twice! But Harry mustn't do that this year! When I think what could have happened to him that night he ran away from home! If the Knight Bus hadn't picked him up, I'm prepared to bet he would have been dead before the Ministry found him."

"But he's not dead, he's fine, so what's the point - "

"Molly, they say Sirius Black's mad, and maybe he is, but he was clever enough to escape from Azkaban, and that's supposed to be impossible. It's been three weeks, and no one's seen hide nor hair of him, and I don't care what Fudge keeps telling the Daily Prophet, we're no nearer catching Black than inventing self-spelling wands. The only thing we know for sure is what Black's after - "

"But Harry will be perfectly safe at Hogwarts."

"We thought Azkaban was perfectly safe. If Black can break out of Azkaban, he can break into Hogwarts."

"But no one's really sure that Black's after Harry - "

There was a thud on wood, and Harry was sure Mr. Weasley had banged his fist on the table.

"Molly, how many times do I have to tell you? They didn't report it in the press because Fudge wanted it kept quiet, but Fudge went out to Azkaban the night Black escaped. The guards told Fudge that Black's been talking in his sleep for a while now. Always the same words: 'He's at Hogwarts...he's at Hogwarts.' Black is deranged, Molly, and he wants Harry dead. If you ask me, he thinks murdering Harry will bring You-Know-Who back to power. Black lost everything the night Harry stopped You-Know-Who, and he's had twelve years alone in Azkaban to brood on that..."
