About the series
A one-shot special from DC Comics (2000) that serves as a guided tour through the dark corners of Batman's city, this issue pairs writers Kelley Puckett and Scott Peterson with artist Paul Ryan to map Gotham's key locations, criminal factions, and the Bat-family's hidden infrastructure. It's a concise, in-universe dossier that deepens the mythos by treating the city itself as a character, offering fans a reference point for the sprawling Bat-titles of the era.
