The collection Batman: Dark Victory #0-13 continues the story of The Long Halloween. It is early in Batman's career in the fight against crime, as James Gordon, Harvey Dent, and the vigilante himself are just beginning their roles as protectors of Gotham. Once a city controlled by organized crime, Gotham City suddenly finds itself in the hands of lawless freaks like Poison Ivy, Mr. Freeze, and the Joker. As he witnesses the dark evolution of his city, the Dark Knight undergoes his transformation into the greatest defender of the city. He faces several threats, including the apparent return of a serial killer named Holiday. Batman's previous investigations into Holiday's murders had revealed that more than one person was responsible for the killings. The question remains: Who is committing Holiday's crimes this time? And how many will die before Batman uncovers the truth?.
