Which Harry Potter book is the only one whose title begins with “Harry Potter and the Prisoner”?

Harry Potter and the Prisoner of Azkaban is the Harry Potter book whose title identifies a prisoner.

Published in 1999, it is the third novel in J.K. Rowling’s seven-book Harry Potter series. The prisoner is Sirius Black, who has escaped from Azkaban prison and is widely believed to be hunting Harry. The story later challenges the assumptions surrounding Black, making mistaken identity and unreliable public belief important parts of its plot.

The novel introduces or expands several memorable elements, including the Dementors, the magical Marauder’s Map, and the time-turner used during the climax. It also gives Harry important information about his parents and their friends. The British title uses “Prisoner of Azkaban,” while the title remains the same in the United States.

The book is sometimes mixed up with the film adaptation, released in 2004. The novel was published much earlier, and its title refers to the fictional wizard prison rather than to Harry himself.
