Thriller
A fiction genre that sustains suspense through danger, pursuit, or an impending crisis, often driving characters toward a high-stakes confrontation.
Suspense: A state of uncertainty and anticipation about what will happen next. Thrillers sustain attention by making danger unresolved and outcomes uncertain.
Crime fiction: Fiction organized around crime, its investigation, or its consequences. Thrillers often draw on crime plots but emphasize imminent danger and urgency.
Psychological thriller: A thriller subgenre that makes mental conflict, perception, or psychological manipulation central to danger. Its threats often arise from unstable trust, memory, or identity.
The Thirty-Nine Steps: John Buchan's 1915 novel about Richard Hannay, who flees a conspiracy and tries to prevent a political assassination. Its hunted protagonist and escalating conspiracy helped establish a durable pursuit pattern.
Whodunit: A mystery plot that asks who committed a crime and withholds the answer until its solution. A whodunit centers on identifying a culprit, unlike a thriller's emphasis on imminent peril.
Dramatic irony: A storytelling effect in which an audience knows something important that one or more characters do not. The audience's knowledge can make a thriller's approaching danger more tense.
Mystery fiction: Fiction centered on discovering the identity, cause, or explanation behind an unknown event. Mysteries foreground solving a puzzle; thrillers foreground surviving or preventing danger.
Political thriller: A thriller subgenre in which political power, institutions, or state conflicts drive danger and suspense. Political conspiracies turn public power struggles into high-stakes crises.
The Spy Who Came in from the Cold: John le Carré's 1963 espionage novel about a British agent drawn into a deceptive Cold War operation. Its suspense grows from betrayal and morally compromised intelligence work.
Action fiction: Fiction that foregrounds physical conflict, daring feats, and fast-paced sequences. Action can prioritize spectacle and movement where thrillers prioritize uncertainty and suspense.
