Make it yours

Three ways to take this prompt somewhere nobody else will.

  1. Give the victim a secret the reader learns before the detective does.
  2. Start with the confession, and make the story about why it's false.
  3. Make the detective wrong at the midpoint, for a good reason.

Writing crime fiction

Not who did it, but why, and whether they'll get away with it.

Crime fiction covers any story built around a crime, and it's often told from the criminal's side. Where a mystery is a puzzle, crime fiction is about people: the pressures that lead to the crime, and what it costs everyone involved.

What readers expect

  • A crime at the heart of the story
  • Moral gray areas
  • Criminals as real people
  • Tension over who gets caught

A tip before you start

Give your criminal a reason the reader understands, even one they'd never act on themselves.
