Three boys entered, and Harry recognized the middle one at once: it was the pale boy from Madam Malkin's robe shop. He was looking at Harry with a lot more interest than he'd shown back in Diagon Alley.

“Is it true?” he said. “They're saying all down the train that Harry Potter's in this compartment. So it's you, is it?”

“Yes,” said Harry. He was looking at the other boys. Both of them were thickset and looked extremely mean. Standing on either side of the pale boy, they looked like bodyguards.

“Oh, this is Crabbe and this is Goyle,” said the pale boy carelessly, noticing where Harry was looking. “And my name's Malfoy, Draco Malfoy.”

Ron gave a slight cough, which might have been hiding a snigger. Draco Malfoy looked at him.

“Think my name's funny, do you? No need to ask who you are. My father told me all the Weasleys have red hair, freckles, and more children than they can afford.”

He turned back to Harry. “You'll soon find out some wizarding families are much better than others, Potter. You don't want to go making friends with the wrong sort. I can help you there.”

He held out his hand to shake Harry's, but Harry didn't take it.

“I think I can tell who the wrong sort are for myself, thanks,” he said coolly.

Draco Malfoy didn't go red, but a pink tinge appeared in his pale cheeks.

“I'd be careful if I were you, Potter,” he said slowly. “Unless you're a bit politer you'll go the same way as your parents. They didn't know what was good for them, either. You hang around with riffraff like the Weasleys and that Hagrid, and it'll rub off on you.”

Both Harry and Ron stood up.

“Say that again,” Ron said, his face as red as his hair.
