Information: - Historical fiction is a literary genre in which the plot takes place in a setting located in the past. Historical fiction can be an ambiguous term: frequently it is used as a synonym for describing the historical novel; however, the term can be applied to works in other narrative formats, such as those in the performing and visual arts like theatre, opera, cinema, television, comics, and graphic novels. - A "whodunit" or "whodunnit" (for "Who [has] done it?" or "Who did it?") is a complex, plot-driven variety of the detective story in which the audience is given the opportunity to engage in the same process of deduction as the protagonist throughout the investigation of a crime. The reader or viewer is provided with the clues 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. - Suspense is a feeling of pleasurable fascination and excitement mixed with apprehension, tension, and anxiety developed from an unpredictable, mysterious, and rousing source of entertainment. The term most often refers to an audience's perceptions in a dramatic work. Suspense is not exclusive to fiction. It may operate whenever there is a perceived suspended drama or a chain of cause is left in doubt, with tension being a primary emotion felt as part of the situation. - The distinction between horror and terror is a standard literary and psychological concept applied especially to Gothic literature and film. Terror is usually described as the feeling of dread and anticipation that "precedes" the horrifying experience. By contrast, horror is the feeling of revulsion that usually occurs "after" something frightening is seen, heard, or otherwise experienced. It is the feeling one gets after coming to an awful realization or experiencing a deeply unpleasant occurrence. In other words, horror is more related to being shocked or scared (being horrified), while terror is more related to being anxious or fearful. Horror has also been defined as a combination of terror and revulsion. - Detective fiction is a subgenre of crime fiction and mystery fiction in which an investigator or a detectiveeither professional or amateurinvestigates a crime, often murder. - Mainstream is current thought that is widespread. It includes all popular culture and media culture, typically disseminated by mass media. It is to be distinguished from subcultures and countercultures, and at the opposite extreme are cult followings and fringe theories. - Science fiction (often shortened to SF, sci-fi or scifi) is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually avoids the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction. - Hardboiled ( or hard - boiled ) fiction is a literary genre that shares some of its characters and settings with crime fiction ( especially detective stories ) . Derived from the romantic tradition which emphasized the emotions of apprehension , awe , horror and terror , hardboiled fiction deviates from that tradition in the detective 's cynical attitude towards those emotions . The attitude is conveyed through the detectives inner monologue describing to the reader ( or , in film , to the viewer ) what he is doing and feeling . The genre 's typical protagonist is a detective , who witnesses daily the violence of organized crime that flourished during Prohibition , while dealing with a legal system that had become as corrupt as the organized crime itself . Rendered cynical by this cycle of violence , the detectives of hardboiled fiction are classic antiheroes . Notable hardboiled detectives include Philip Marlowe , Mike Hammer , Sam Spade , and The Continental Op. - Crime fiction is the literary genre that fictionalises crimes, their detection, criminals, and their motives. It is usually distinguished from mainstream fiction and other genres such as historical fiction or science fiction, but the boundaries are indistinct. Crime fiction has multiple subgenres, including detective fiction (such as the whodunit), courtroom drama, hard-boiled fiction and legal thrillers. Suspense and mystery are key elements that are nearly ubiquitous to the genre. - In ordinary language, a crime is an unlawful act punishable by a state or other authority. The term "crime" does not, in modern criminal law, have any simple and universally accepted definition, though statutory definitions have been provided for certain purposes. The most popular view is that crime is a category created by law; in other words, something is a crime if declared as such by the relevant and applicable law. One proposed definition is that a crime or offence (or criminal offence) is an act harmful not only to some individual or individuals but also to a community, society or the state ("a public wrong"). Such acts are forbidden and punishable by law. - The legal thriller is a subgenre of thriller and crime fiction in which the major characters are lawyers and their employees. The system of justice itself is always a major part of these works, at times almost functioning as one of the characters. In this way, the legal system provides the framework for the legal thriller much as the system of modern police work does for the police procedural.
