Mystery fiction is a genre of fiction usually involving a mysterious death or a crime to be solved. In a closed circle of suspects, each suspect must have a credible motive and a reasonable opportunity for committing the crime. The central character must be a detective who eventually solves the mystery by logical deduction from facts fairly presented to the reader. Sometimes mystery books are nonfictional.
