For twelve long years, the dread fortress of Azkaban held an infamous prisoner named Sirius Black. Convicted of killing thirteen people with a single curse, he was said to be the heir apparent to the Dark Lord, Voldemort. Now he has escaped, leaving only two clues as to where he might be headed: Harry Potter's defeat of you-know-who was Black's downfall as well. And the Azkaban guards heard Black muttering in his sleep, "He's at Hogwarts . . . he's at Hogwarts."J.K.
