Crime

A crime story is often about a crime that is being committed or was committed, but can also be an account of a criminal's life. A mystery story follows an investigator as they attempt to solve a puzzle (often a crime). The details and clues are presented as the story continues and the protagonist discovers them and by the end of the story the mystery is solved. For example, in the case of a crime mystery, the perpetrator and motive behind the crime are revealed and the perpetrator is brought to justice. Mystery novels are often written in series, which facilitates a more in-depth development of the primary investigator.

• Cozy mysteries

• Detective story: A story about a detective or person, either professional or amateur, who has to solve a crime that was committed. They must figure out who committed the crime and why. Sometimes, the detective must figure out 'how' the criminal committed the crime if it seems impossible.

• Whodunit: This is a complex, plot-driven variety of the detective story in which the audience is given the opportunity to engage in the same process of deduction as the protagonist throughout the investigation of a crime. The reader or viewer is provided with the clues from which the identity of the perpetrator may be deduced before the story provides the revelation itself at its climax. The investigation is usually conducted by an eccentric amateur or semi-professional detective.

Gentleman thief: Centers around particularly well-behaving and apparently well-bred thieves. They rarely bother with anonymity or force, preferring to rely on their charisma, physical attractiveness, and clever misdirection to steal the most unobtainable objects – sometimes for their own support, but mostly for the thrill of the act itself.

Gong'an fiction: A subgenre of historical crime fiction that involves government magistrates who solve criminal cases.

Legal thriller: This subgenre of thriller and crime fiction presents stories in which the major characters are lawyers, judges, and/or their employees. Examples include Primal Fear (1993) and Blood Defense (2016).

Locked-room mysteries

Murder mystery: A mystery story that focuses on homicides. Usually, the detective must figure out who killed one or several victims. They may or may not find themselves or loved ones in danger because of this investigation. The genre often includes elements of the suspense story genre, or of the action and adventure genres.

Noir fiction

Hardboiled: This is a literary genre sharing the setting with crime fiction (especially detective stories). Though deriving from the romantic tradition—which emphasized the emotions of apprehension, horror and terror, and awe—hardboiled fiction deviates from the tradition in the detective's cynical attitude towards those emotions. The attitude is conveyed through the detective's self-talk describing to the reader what he is doing and feeling.
