Something is terribly wrong with Batman. The greatest detective in the world can't pin down the source of this creeping dread--of his own inner demons and a looming mortality. Meanwhile, real demons roam the shadows as an ancient melody haunts the Gotham night. Here, now, the curtains rise, and the eerie tune streams in--who is human, who is demon, and who is to tell? As Batman investigates the songs and the demons of Gotham, he is forced to confront the oldest question: Has there been a demon within him all along...and if so, what does it want...and why hasn't it taken over yet? Collects Detective Comics #1062-1065.
