For the fourth straight day letters arrive for Harry, but [Uncle Vernon] stays home from work to burn the letters and board up the cracks on the outside of the house.

A fifth set of letters arrive for Harry, inside the [Dursleys]' delivery of two dozen eggs.

After letters penetrate the [Dursleys]' chimney and begin attacking them, [Uncle Vernon] takes the family and drives all day long, muttering, finally stopping at a hotel in Cokeworth.

After letters are delivered to Harry at the [hotel], [Uncle Vernon] drives the family to the seashore, buys a gun, and takes them out in a boat to the hut-on-the-rock, where they all uncomfortably go to bed.

Trying unsuccessfully to sleep on the floor, Harry instead counts down the minutes to midnight, the start of his eleventh birthday, hearing noises outside and finally a knock on the door.

Rubeus Hagrid makes an entrance at the stroke of midnight by banging down the door of the hut-on-the-rock, terrifying Harry and the [Dursleys].

Walking into the hut, Hagrid greets Harry with a birthday cake, introduces himself, and cooks some sausages in the fireplace.

Discovering that Harry knows nothing of Hogwarts, his parents, or the wizarding world, Hagrid yells at the [Dursleys] - and informs Harry that he is a wizard, and hands him his [Hogwarts letter].

A disbelieving Harry learns the story of his life from Hagrid, discovering that his parents were [head boy and girl] at Hogwarts, that Voldemort killed them and tried to kill Harry, and that Harry survived and destroyed Voldemort, making him famous.
