Harry, who was starting to feel warm and sleepy, looked up at the High Table again. Hagrid was drinking deeply from his goblet. Professor McGonagall was talking to Professor Dumbledore. Professor Quirrell, in his absurd turban, was talking to a teacher with greasy black hair, a hooked nose, and sallow skin.

It happened very suddenly. The hook nosed teacher looked past Quirrell’s turban straight into Harry’s eyes—and a sharp, hot pain shot across the scar on Harry’s forehead.

“Ouch!” Harry clapped a hand to his head.

“What is it?” asked Percy.

“N-nothing.”

The pain had gone as quickly as it had come. Harder to shake off was the feeling Harry had gotten from the teacher’s look—a feeling that he didn’t like Harry at all.

“Who’s that teacher talking to Professor Quirrell?” he asked Percy.

“Oh, you know Quirrell already, do you? No wonder he’s looking so nervous, that’s Professor Snape. He teaches Potions, but he doesn’t want to—everyone knows he’s after Quirrell’s job. Knows an awful lot about the Dark Arts, Snape.”

Harry watched Snape for a while, but Snape didn’t look at him again.
