Batman: Dark Victory is a 14-part comic book limited series (including a #0 issue) written by Jeph Loeb and drawn by Tim Sale. The series is a sequel to Batman: The Long Halloween and was originally published from 1999 to 2000 by DC Comics. The series takes place primarily during the third/fourth year of Batman's career. The plot centers on a series of murders involving Gotham City police officers by a mysterious serial killer only known as The Hangman. Central to the storyline is a territory war between Two-Face and the remnants of the Falcone mob, led by Sofia Falcone.
The story is also a re-telling of the origins of Batman's sidekick Robin and his adoption by Bruce Wayne. The story brings closure to many characters introduced in Frank Miller's Batman: Year One.
In 2004, Loeb and Sale produced a follow-up titled Catwoman: When in Rome, focusing on Catwoman's movements in Italy. The story takes place during the events of Dark Victory, between Valentine's Day (when Catwoman leaves Gotham) and Thanksgiving.
