Then, on the very last day of the holidays, something happened that made Harry positively dread his return to school.
“Harry, dear,” said Mrs. Weasley, poking her head into his and Ron’s bedroom, where the pair of them were playing wizard chess watched by Hermione, Ginny and Crookshanks, “could you come down to the kitchen? Professor Snape would like a word with you.”
Harry did not immediately register what she had said; one of his castles was engaged in a violent tussle with a pawn of Ron’s and he was egging it on enthusiastically.
“Squash him—squash him, he’s only a pawn, you idiot. Sorry, Mrs. Weasley, what did you say?”
“Professor Snape, dear. In the kitchen. He’d like a word.”
Harry’s mouth fell open in horror. He looked around at Ron, Hermione and Ginny, all of whom were gaping back at him. Crookshanks, whom Hermione had been restraining with difficulty for the past quarter of an hour, leapt gleefully on to the board and set the pieces running for cover, squealing at the top of their voices.
“Snape?” said Harry blankly.
“Professor Snape, dear,” said Mrs. Weasley reprovingly. “Now come on, quickly, he says he can’t stay long.”
“What’s he want with you?” said Ron, looking unnerved as Mrs. Weasley withdrew from the room. “You haven’t done anything, have you?”
“No!” said Harry indignantly, racking his brains to think what he could have done that would make Snape pursue him to Grimmauld Place. Had his last piece of homework perhaps earned a T?
A minute or two later, he pushed open the kitchen door to find Sirius and Snape both seated at the long kitchen table, glaring in opposite directions. The silence between them was heavy with mutual dislike. A letter lay open on the table in front of Sirius.
“Er,” said Harry, to announce his presence.
Snape looked around at him, his face framed between curtains of greasy black hair.
“Sit down, Potter.”
“You know,” said Sirius loudly, leaning back on his rear chair legs and speaking to the ceiling, “I think I’d prefer it if you didn’t give orders here, Snape. It’s my house, you see.”
An ugly flush suffused Snape’s pallid face. Harry sat down in a chair beside Sirius, facing Snape across the table.
“I was supposed to see you alone, Potter,” said Snape, the familiar sneer curling his mouth, “but Black—”
“I’m his godfather,” said Sirius, louder than ever.
“I am here on Dumbledore’s orders,” said Snape, whose voice, by contrast, was becoming more and more quietly waspish, “but by all means stay, Black, I know you like to feel… involved.”
“What’s that supposed to mean?” said Sirius, letting his chair fall back on to all four legs with a loud bang.
“Merely that I am sure you must feel—ah—frustrated by the fact that you can do nothing useful,” Snape laid a delicate stress on the word, “for the Order.”
