Batman- The Killing Joke is Alan Moore's unforgettable meditation on the razor-thin line between sanity and insanity, heroism and villainy, comedy and tragedy. One bad day is all it takes 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 the Commissioner's brilliant and beautiful daughter Barbara to do it.
