Hardboiled

Hardboiled (or hard-boiled) fiction is a literary genre that shares some of its characters and settings with crime fiction (especially detective stories). The genre's typical protagonist is a detective who witnesses the violence of organized crime that flourished during Prohibition (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 Philip Marlowe, Mike Hammer, Sam Spade, Lew Archer, and The Continental Op. Wikipedia definition
