Batman: The Long Halloween is a 13-issue American comic book limited series written by Jeph Loeb and illustrated by Tim Sale, published by DC Comics from 1996 to 1997. Set during the early years of Batman's career, the story unfolds as a sprawling, noir-infused mystery that spans an entire year in Gotham City. A serial killer known only as "Holiday" murders members of the Falcone crime family on major holidays, beginning with Halloween. Batman, Police Commissioner James Gordon, and District Attorney Harvey Dent form an uneasy alliance to bring the killer to justice, but the investigation strains their trust in one another and pushes each man toward his own breaking point.
The series is widely regarded as one of the definitive Batman stories, celebrated for its intricate plotting, moody artwork, and deep exploration of the transition from organized crime to the rise of costumed "freaks" in Gotham's underworld. Tim Sale's distinctive, shadow-heavy art style and Jeph Loeb's character-driven writing give the book a timeless, cinematic quality. The story also serves as a spiritual successor to Loeb and Sale's earlier collaboration, Batman: Haunted Knight, and is set in the same continuity as their later work, Batman: Dark Victory, which continues the narrative threads left dangling at the end of The Long Halloween.
Central to the story is the tragic arc of Harvey Dent, whose descent into becoming the villain Two-Face is portrayed with Shakespearean gravity. The series also features a vast rogues' gallery of Batman villains, including Catwoman, the Joker, Poison Ivy, the Riddler, Scarecrow, and Mad Hatter, each woven into the mystery in clever and surprising ways. The identity of the Holiday killer remains a closely guarded secret until the final issue, and the revelation has become one of the most discussed and debated twists in Batman lore.
The Long Halloween has had a lasting influence on Batman media beyond comics. Its tone, structure, and thematic focus on the fall of Harvey Dent heavily inspired Christopher Nolan's film The Dark Knight, and elements of the story have been adapted into animated films, video games, and other DC projects. The series remains a perennial bestseller in collected editions and is frequently recommended as an essential starting point for readers new to Batman comics.
