Nick and Nora Charles in the context of "Hardboiled"

Hardboiled (or hard-boiled) fiction is a literary genre that shares some of its characters and settings with crime fiction (especially detective fiction and noir fiction). The genre's typical protagonist is a detective who battles the violence of organized crime that flourished during Prohibition in the United States (1920–1933) and its aftermath, while dealing with a legal system that has become as corrupt as the organized crime itself. Rendered cynical by this cycle of violence, the detectives of hardboiled fiction are often antiheroes. Notable hardboiled detectives include Dick Tracy, Philip Marlowe, Nick Charles, Mike Hammer, Sam Spade, Lew Archer, Slam Bradley, and The Continental Op.
