Harry Potter and the Sorcerer's Stone
"Harry Potter come and live here!"
"It's the best place for him," said Dumbledore firmly. "His aunt and uncle will be able to explain everything to him when he's older. I've written them a letter." (1.81-82)
The room held no sign that another boy lived in the house, too. (2.1)
Harry was used to spiders, because the cupboard under the stairs was full of them, and that was where he slept.
When he was dressed he went down the hall into the kitchen. The table was almost hidden beneath all Dudley's birthday presents. (2.13-14)
