Escape
After losing his temper and inflating his rude Aunt Marge, Harry runs away from the Dursleys. He learns that Sirius Black has escaped from Azkaban and is believed to be a follower of Voldemort who betrayed Harry's parents. The wizarding world is terrified. Dementors are sent to guard Hogwarts.

The Shrieking Shack
Ron's rat, Scabbers, is dragged into the Shrieking Shack by a large black dog, which turns out to be Sirius. Lupin arrives and explains the truth: Scabbers is Peter Pettigrew, an Animagus, a wizard who can turn into an animal, who betrayed Harry's parents and framed Sirius. But Lupin is a werewolf, and when the moon rises, he transforms, and Pettigrew escapes.
