Pick up any well-known suspense or thriller writer’s work and look at the chapter endings. You’ll see how most of the time each chapter ends on a suspenseful note and throws the reader forward into the next chapter. The most experienced suspense writers start the next chapter somewhere else or with other characters.
In literary novels, of course, the suspense is often more subtle. All forms of fiction have one thing in common: the chapter endings arouse the reader’s curiosity about what will happen next.
