The Thriller fiction genre, sometimes called suspense fiction, is a genre of literature that typically entails fast-paced plots, numerous action scenes, and limited character development. One example is that: the hero, who may even be an ordinary citizen drawn into danger and intrigue by circumstances beyond their control faces danger alone or in the company of a small band of companions. The protagonist may be a law enforcement agent, a journalist, or a soldier, but typically he or she is cut off from the resources of "their" organization. Part of the allure of thrillers comes from not only what their stories are about but how they are told. The plot of a thriller is usually driven by the villain, who presents obstacles that the hero must overcome. Not all thrillers are suspense novels; but many suspense novels are thrillers. The average thriller is longer than the average mystery, which makes a brisk pace crucial to success.
