Back in Arkham Asylum, Joker learns of a new technology he wants to acquire and escapes, setting out on a mission designed to break the Commissioner, forcing him to abandon his ideals as a police officer. In a violent home invasion he shoots and cripples Barbara, then takes Gordon hostage. Batman races to rescue Gordon, ultimately confronting his arch-foe in an amusement park fun house. This edgy adaptation by Hard Case Crime novelist Christa Faust expands upon the cast and adds intricate layers to the events of the graphic novel, further examining the nature of morality.
