As the story opens, mysterious goings-on ruffle the self-satisfied suburban world of the Dursleys, culminating in a trio of strangers depositing the Dursleys' infant nephew Harry in a basket on their doorstep. After 11 years of disregard and neglect at the hands of his aunt, uncle and their swinish son Dudley, Harry suddenly receives a visit from a giant named Hagrid, who informs Harry that his mother and father were a witch and a wizard, and that he is to attend Hogwarts School of Witchcraft and Wizardry himself. Most surprising of all, Harry is a legend in the witch world for having survived an attack by the evil sorcerer Voldemort, who killed his parents and left Harry with a lightning-shaped scar on his forehead.
