Writing mystery books

Who did it? You get every clue and a fair shot at the answer.

A mystery opens with a puzzle, usually a death, and closes with the solution. In between, a detective (professional or not) gathers clues and suspects while the reader tries to get there first. A mystery looks backward, at a crime that has already happened.

What readers expect

  • A crime or puzzle early on
  • Clues, suspects and red herrings
  • A detective the reader follows
  • A solution that is surprising but fair

A tip before you start

Play fair. Every clue your detective uses should appear on the page first, ideally hidden in plain sight.
