Mystery (351)

Whether its solving a crime or finding an explanation for a puzzling circumstance, the main cast willingly or reluctantly become investigators who must work to answer the who, what, why, and/or how of the current dilemma. The narrative of mystery stories is always on collecting evidence, identifying suspects, and theorizing possible scenarios for the unexplainable, before finally capturing the perpetrator or resolving the current situation. Almost always, the audience has the same information as the main characters and anticipation is directed towards discovering the explanation, not what will transpire after the answer is found. Contrast with Suspense or Horror where often the audience has more information than the cast, which heightens the tension or fear of what will happen next.
