How did an average citizen become Gotham's greatest evil? Almost thirty years ago, screenwriter Alan Moore and artist Brian Bolland gave us a look at the events that made the Joker what he is. Now their nightmare returns to us in a new, final edition. The Joker is Batman's most implacable enemy, a mad genius of crime whose bizarre adventures confuse even the greatest detective in the world. But Joker wasn't always like that. Before he became a bloody clown, before a single, fateful day scarred his face forever and made him lose his mind, he was one of those the Dark Knight swore to protect - an ordinary, little man. What made an average citizen become the greatest evil that Gotham City has ever known? Can Batman stop the Joker from dragging Commissioner Gordon and his daughter Barbara into a vortex of murderous insanity? And can the two enemies stop their eternal duel before it is too late for both of them? Presented for the first time in Bolland's refined, stark and poignant colors, Batman: The Terrible Joke is Moore's unforgettable reflection on the fine line that separates sanity from insanity, hero from villain, and comedy from tragedy.
