Batman: The Long Halloween

TL;DR — The Essence

Someone is murdering members of Gotham’s crime families, always on a holiday, always leaving behind a single clue tied to that date. Batman teams with District Attorney Harvey Dent and Lieutenant Jim Gordon to catch the killer before the calendar runs out — a case that spans a full year and pulls in nearly every major figure in Batman’s rogues gallery along the way. The investigation’s fallout is also the origin of one of Batman’s most tragic villains.

Why It’s Worth Reading

1. It Plays as a Genuine Mystery, Not Just a Superhero Story

Most Batman comics tell you upfront who the threat is. The Long Halloween withholds the killer’s identity for the entire 13-issue run, structured like a whodunit where Batman functions as detective first and vigilante second — a rarer approach than the premise might suggest.

2. It’s the Direct Blueprint for The Dark Knight’s Tone

Christopher Nolan has called the book “more than a comic book… an epic tragedy,” and its noir-inflected take on organized crime, Harvey Dent’s fall, and Gotham’s institutional corruption maps closely onto Nolan’s Dark Knight trilogy, more so than almost any other single source.

3. Tim Sale’s Art Defines an Entire Era of Batman Visually

Sale’s exaggerated, shadow-heavy style — equal parts German Expressionism and classic noir cinema — became so associated with “serious” Batman storytelling that it influenced how the character has been drawn for decades after.

Creative Team

The Long Halloween was written by Jeph Loeb, illustrated by Tim Sale, colored by Gregory Wright, and lettered by Richard Starkings. It was originally published as a 13-issue limited series by DC Comics between December 1996 and 1997, following three earlier Halloween-themed one-shots by the same team (collected separately as Batman: Haunted Knight). In 2026, it’s one of six titles included in DC’s Compact Comics boxed set — the small, $9.99-per-volume format DC launched in 2024 to bring classic stories to new readers, alongside Watchmen, The Dark Knight Returns, All-Star Superman, Kingdom Come, and DC: The New Frontier.

Who Should Read This

This is one of the small handful of Batman stories usually named alongside The Dark Knight Returns and Year One as essential reading, and it pairs especially well with Year One — both are grounded, detective-forward takes on the character rather than pure action. It also works well as an introduction to Harvey Dent before his transformation into Two-Face, for anyone who’s only encountered the villain in film.

If you want to see where a huge amount of modern “Batman as detective” media actually comes from, this is close to the source.
