Harry Potter and the Prisoner of Azkaban games loosely based on "Harry Potter and the Prisoner of Azkaban" were also released for several platforms, and most obtained favourable reviews. Harry is back at the Dursleys for the summer holidays, where he sees on Muggle television that a convict named Sirius Black has escaped, though with no mention of what facility he has broken out of. Harry involuntarily inflates Aunt Marge when she comes to visit after she insults Harry and his parents. This leads to his running away and being picked up by the Knight Bus. He travels to the Leaky Cauldron where he meets Cornelius Fudge,
Harry Potter and the Philosopher's Stone and Madam Hooch, the Quidditch coach, who is strict, but a considerate and methodical teacher. The poltergeist Peeves wanders around the castle causing trouble wherever he can. In the book, Rowling introduces an eclectic cast of characters. The first character to be introduced is Vernon Dursley, Harry's uncle. Most of the actions centre on the eponymous hero Harry Potter, an orphan who escapes his miserable childhood with the Dursley family. Rowling imagined him as a "scrawny, black-haired, bespectacled boy who didn't know he was a wizard", and says she transferred part of her pain about losing her mother to him.
