From the creator of the classic graphic novel Enemy Ace: War Idyll comes this new, lushly painted tale of the Dark Knight. In this deeply psychological tale, we learn that Batman is having nightmares about committing murder -- and that these nightmares reassure him that he will never cross that line. But when a string of murders begins that bear a strange resemblance to Batman's grisly dreams, the dreams stop -- leading the Dark Knight to wonder if, somehow, he has become a killer.
