where does harry stay in prisoner of azkaban
Harry Potter and the Prisoner of Azkaban 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, the Minister for Magic, who asks Harry to stay in Diagon Alley for the remaining three weeks before the start of the school year at Hogwarts.
Rubeus Hagrid Readers first discover why Hagrid was expelled from Hogwarts in the second novel. It is revealed that Hagrid was a student at Hogwarts at the same time as Tom Marvolo Riddle, the wizard who later became Lord Voldemort. Hagrid was expelled during his third year, after being caught in the company of Aragog, a dangerous acromantula: this already serious crime seemed worse than it was, due to the belief that the acromantula was "The Monster of Slytherin", and that Hagrid had released it from the Chamber of Secrets and allowed it to attack students. Aragog escapes into the dark forest and starts a colony of spiders. The belief of Hagrid's guilt was encouraged by Tom Riddle, the actual criminal, who had been using the true monster (a basilisk) to attack students, and who had framed Hagrid to prevent the school from being closed, because he didn't want to return to the orphanage whence he had come. During the events of the second book, the Basilisk is unleashed once again and Hagrid is sent to the prison of Azkaban, as he is believed again to be responsible for the attacks. However, before being arrested, Hagrid tells Harry and Ron to "follow the spiders", so that they can meet Aragog and discover the identity of the true monster. After Harry defeats the Basilisk and uncovers the truth, Hagrid is freed from prison.
