True crime is a nonfiction literary, podcast, and film genre in which the author examines a crime and details the actions of people associated with and affected by criminal events. It is a cultural phenomenon that can refer to the promotion of sensationalized and emotionally charged content around the subject of violent crime, for the general public.

William Roughead (1870–1952) was a Scottish lawyer and amateur criminologist, as well as an editor and essayist on "matters criminous". He was an important early practitioner of the modern "true crime" literary genre.
