Make it yours

Three ways to take this prompt somewhere nobody else will.

  1. Open with the threat already in motion, not the setup.
  2. Make the person helping your hero the one to worry about.
  3. End a scene on a phone call, a knock or a name.

Writing thriller books

Something terrible is coming. Can they stop it in time?

Where a mystery looks back at a crime, a thriller looks forward at a threat. The reader often knows more than the hero, and the tension comes from watching danger close in. Short chapters, high stakes and a ticking clock are the tools of the trade.

What readers expect

  • A clear, escalating threat
  • A hero under pressure
  • Twists and reversals
  • Pace: little time to breathe

A tip before you start

Put a clock on it. A deadline the reader can count down turns every scene into a race.
