Batman: The Killing Joke
I know, I promised no more Alan Moore. And certainly no more Batman. But look, c'mon, this one is DIFFERENT. For one thing, it really IS a novel -- a single story, conceived as such, and with all the horrific impact that only a single shot (so to speak) can deliver. And Dave Gibbons, of WATCHMEN and GIVE ME LIBERTY has never EVER been better. Not to mention the complete and utter lack of a 'comic book' happy ending. An absolute keeper.
Fantastic comic. You can't go wrong with a Batman graphic novel, and this is a classic.
The ultimate Batman story.
