Climax (narrative) in the context of "Locked room mystery"

Thriller is a genre of fiction with numerous, often overlapping, subgenres, including crime, horror, and detective fiction. Thrillers are characterized and defined by the moods they elicit, giving their audiences heightened feelings of suspense, excitement, surprise, anticipation and anxiety. This genre is well suited to film and television.

A thriller generally keeps its audience on the "edge of their seats" as the plot builds towards a climax. The cover-up of important information is a common element. Literary devices such as red herrings, plot twists, unreliable narrators, and cliffhangers are used extensively. A thriller is often a villain-driven plot, whereby they present obstacles that the protagonist or hero must overcome.

A spoiler is an element of a disseminated summary or description of a media narrative that reveals significant plot elements, with the implication that the experience of discovering the plot naturally, as the creator intended it, has been robbed ("spoiled") of its full effect. Typically, the conclusion of a plot, including the climax and ending, is regarded as highly susceptible to spoilers. Plot twists are also prone to spoilers. Any narrative medium can produce spoilers, although they are usually associated with movies and television shows. Some people attempt to avoid being "spoiled" while others seek out spoilers to learn as much as possible about a narrative before experiencing it. Spoilers have become more common in the present day with the rise of social media, which provides an outlet for people to spread spoilers.

There are three types of spoilers: short spoilers, long spoilers, and thematic spoilers. Short spoilers reveal the plot ending in a very brief and less detailed manner, without any summary or explanation of themes in the story, typically spanning one to three sentences. Long spoilers usually provide more context and range between two and five sentences. They provide a summary and reveal the ending of a story. Lastly, thematic spoilers reveal a story's unifying theme as well as providing a synopsis of the plot and revealing the ending. They range from three to six sentences in length. The general consensus is that there are only negative effects of spoilers. However, research shows that it is short and long spoilers that can cause negative effects, while thematic spoilers generally have a positive effect.

A whodunit (less commonly spelled as whodunnit; a colloquial elision of "Who [has] done it?") is a complex plot-driven variety of detective fiction in which the puzzle regarding who committed the crime is the main focus. The reader or viewer is provided with the clues to the case, from which the identity of the perpetrator may be deduced before the story provides the revelation itself at its climax. The investigation is usually conducted by an eccentric, amateur, or semi-professional detective.

In narratology and comparative mythology, the hero's quest or hero's journey, also known as the monomyth, is the common template of stories that involve a hero who goes on an adventure, is victorious in a decisive crisis, and comes home changed or transformed.

Earlier figures had proposed similar concepts, including psychoanalyst Otto Rank and amateur anthropologist Lord Raglan. Eventually, hero myth pattern studies were popularized by Joseph Campbell, who was influenced by Carl Jung's analytical psychology. Campbell used the monomyth to analyze and compare religions. In his book The Hero with a Thousand Faces (1949), he describes the narrative pattern as follows:
