Following a brutal series of murders taking place on Halloween, Thanksgiving, and Christmas, Gotham City's young vigilante known as the Batman sets out to pursue the mysterious serial killer alongside police officer James Gordon and district attorney Harvey Dent.
Batman: The Long Halloween is a 13-issue American comic book limited series written by Jeph Loeb with art by Tim Sale. It was originally published by DC Comics in 1996 and 1997. It was the follow-up to three Batman: Legends of the Dark Knight Halloween Specials which were reprinted in Batman: Haunted Knight by the same creative team. The series' success led to Loeb and Sale to reteam for two sequels, Batman: Dark Victory and Catwoman: When in Rome, which are set concurrently. A third sequel, a 10-issue limited series entitled The Last Halloween, began publication on September 25, 2024.
