Tips for thriller writers

Start the clock

A deadline turns tension into urgency. Tell the reader how long the hero has.

Raise the stakes in steps

Each act should threaten something bigger: first the hero, then someone they love, then many people.

Short chapters

Many bestselling thrillers use short chapters ending on a question to keep readers turning pages.
