Minotaur Books/Malice Domestic Best First Traditional Mystery Novel Competition: This is an international contest for novel manuscripts in the malice domestic genre, for writers who have never been the author of any published mystery novel. “Murder or another serious crime or crimes is at the heart of the story. Whatever violence is necessarily involved should be neither excessive nor gratuitously detailed, nor is there to be explicit sex. The suspects and the victims should know each other. There are a limited number of suspects, each of whom has a credible motive and reasonable opportunity to have committed the crime. The person who solves the crime is the central character. The “detective” is an amateur, or, if a professional (private investigator, police officer) is not hardboiled and is as fully developed as the other characters. The detective may find him or herself in serious peril, but he or she does not get beaten up to any serious extent. All of the cast represent themselves as individuals, rather than large impersonal institutions like a national government, the mafia, the CIA, etc.” The work must be at least 65,000 words. The prize is $10,000 advance against royalties, and the deadline is 30 November 2026. Minotaur is an imprint of Macmillan.
