Batman: The Killing Joke

Arguably the most famous Batman story of all time. Joker's origins, Barbara's fate and the battle that rages on and on between Batman & Joker.

There is sympathy to be had for the Joker. His flashbacks revealing what happened in his life before he became a cartoon version of himself. But of course, the Joker is still the Joker and his atrocities are legend, especially here.

A definite must read for the Batman fan.
