Detective Comics #698

In "The Tomb," Batman, Robin, and Nightwing infiltrate a rogue cop's underground prison in a high-stakes trap for the vigilante known as Lock-Up—but when the operation unravels, it's Robin who's captured, leaving his allies to confront the deadly consequences of a justice system gone too far. Written by Chuck Dixon and illustrated with gritty precision by Graham Nolan, this 1996 issue blends tense undercover drama with the moral complexity that defines Gotham’s darkest corners. The cover, a striking collaboration by Nolan and Bill Sienkiewicz, captures the shadowed intensity of the story’s central mystery.
