“Where was I?” said Hagrid, but at that moment, Uncle Vernon, still ashen-faced but looking very angry, moved into the firelight.

“He's not going,” he said.

Hagrid grunted.

“I'd like ter see a great Muggle like you stop him,” he said.

“A what?” said Harry, interested.

“A Muggle,” said Hagrid, “it's what we call nonmagic folk like them. An’ it's your bad luck you grew up in a family o’ the biggest Muggles I ever laid eyes on.”

“We swore when we took him in we'd put a stop to that rubbish,” said Uncle Vernon, “swore we'd stamp it out of him! Wizard indeed!”

“You knew ?” said Harry. “You knew I'm a — a wizard?”

“Knew!” shrieked Aunt Petunia suddenly. “Knew! Of course we knew! How could you not be, my dratted sister being what she was? Oh, she got a letter just like that and disappeared off to that — that school — and came home every vacation with her pockets full of frog spawn, turning teacups into rats. I was the only one who saw her for what she was — a freak! But for my mother and father, oh no, it was Lily this and Lily that, they were proud of having a witch in the family!”

She stopped to draw a deep breath and then went ranting on. It seemed she had been wanting to say all this for years.

“Then she met that Potter at school and they left and got married and had you, and of course I knew you'd be just the same, just as strange, just as — as — abnormal — and then, if you please, she went and got herself blown up and we got landed with you!”

Harry had gone very white. As soon as he found his voice he said, “Blown up? You told me they died in a car crash!”

“CAR CRASH!” roared Hagrid, jumping up so angrily that the Dursleys scuttled back to their corner. “How could a car crash kill Lily an’ James Potter? It's an outrage! A scandal! Harry Potter not knowin’ his own story when every kid in our world knows his name!”
