It is Crime fiction
Genre of novel or short story in which a mystery is solved mainly by the action of a professional or amateur detective. Where the mystery to be solved concerns a crime, the work may be called crime fiction. The traditional formula for the detective story starts with a seemingly irresolvable mystery, typically a murder, features the astute, often unconventional detective, a wrongly accused suspect to whom the circumstantial evidence points, and concludes with a startling or unexpected solution to the mystery, during which the detective explains how he or she solved the mystery. The earliest work of detective fiction as understood today was 'The Murders in the Rue Morgue' (1841) by Edgar Allan Poe, and his detective Dupin became the model for those who solved crimes by deduction from a series of clues.
