The dread fortress of Azkaban has held a prisoner for twelve years known as Sirius Black. He has been convicted of killing 13 people using a single curse. Legend has it that he was the heir to Voldemort, the Dark Lord. Black has escaped Azkaban and has left a couple of clues that can give an idea of where he might be heading. The first clue is the fact that Harry has defeated someone who was also the downfall of Black. Sirius Black was also heard talking in his sleep that “he is at Hogwarts” repeatedly. This gives one the feeling that Harry is not safe, even while he is attending Hogwarts because someone in the school is a traitor and has given him up. Harry has to confront the most dangerous wizard possible during his third year of school at Hogwarts – the same evil wizard who is responsible for the death of his parents.
