Critically acclaimed author Alan Moore redefined graphic novel story-telling with Watchmen and V for Vendetta. In Batman: The Killing Joke, he takes on the origin of comics' greatest super-villain, The Joker, and changes Batman's world forever. ONE BAD DAY. According to the grinning engine of madness and mayhem known as the Joker, that's all that separates the sane from the psychotic. Freed once again from the confines of Arkham Asylum, he's out to prove his deranged point. And he's going to use Gotham City's top cop, Commissioner Jim Gordon, and his brilliant and beautiful daughter Barbara to do it.
