(W) Jeff Lemire (A/CA) Andrea Sorrentino Arkham Asylum is home to many of Batman's worst enemies--including the most dangerous one of them all: The Joker. No psychologist or psychotherapist has ever been able to break through the insanity that imprisons The Joker's mind. But Dr. Ben Arnell is sure that he will be the one to finally reach the man inside the madness--and cure him. And he's absolutely certain that no matter what he goes through at work, he can keep that darkness far away from his family. He is very, very wrong. Collects JOKER: KILLER SMILE #1-3 and BATMAN: THE SMILE KILLER #1.
