Sleeper

In this taut 2006 series from Spain's Norma Editorial, a cold-case detective's investigation into a string of brutal murders leads him to a mysterious figure known only as "the Sleeper"—a traumatized amnesiac whose fragmented memories may hold the key to the killings. Over four issues, writer and artist collaborate to craft a noir-tinged psychological thriller where the line between victim and predator blurs. Though brief, Sleeper stands as a compact, atmospheric example of early 2000s European crime comics, showcasing Norma's commitment to moody, character-driven genre work.
