Uncle Vernon Threatens Harry About Marge Dursley's Visit

PAGES: 18-21

Uncle Vernon sternly warns Harry to behave while Marge Dursley is visiting. He makes it clear that if Harry slips up and reveals anything about his magical abilities, there will be consequences. Uncle Vernon insists that Harry must stick to the lie about attending St. Brutus's. Harry, in return, strikes a deal: if Uncle Vernon signs his Hogsmeade permission form, Harry will cooperate. Uncle Vernon reluctantly agrees, setting conditions on Harry's behavior during Marge's stay.
