Crime fiction

The One Thousand and One Nights (Arabian Nights) contains the earliest known examples of crime fiction.^[3] One example of a story of this genre is the medieval Arabic tale of "The Three Apples", one of the tales narrated by Scheherazade in the Arabian Nights. In this tale, a fisherman discovers a heavy locked chest along the Tigris River, and he sells it to the Abbasid Caliph, Harun al-Rashid, who then has the chest broken open, only to find inside it the dead body of a young woman who was cut into pieces. Harun orders his vizier, Ja'far ibn Yahya, to solve the crime and find the murderer within three days, or be executed if he fails his assignment.^[4] The story has been described as a "whodunit" murder mystery^[5] with multiple plot twists.^[6] The story has detective fiction elements.^[7]

Two other Arabian Nights stories, "The Merchant and the Thief" and "Ali Khwaja", contain two of the earliest fictional detectives, who uncover clues and present evidence to catch or convict a criminal, with the story unfolding in normal chronology and the criminal already being known to the audience. The latter involves a climax where titular detective protagonist Ali Khwaja presents evidence from expert witnesses in a court.^[8] "The Hunchback's Tale" is another early courtroom drama, presented as a suspenseful comedy.^[3]

The earliest known modern crime fiction is E. T. A. Hoffmann's 1819 novella "Mademoiselle de Scudéri". Also, Thomas Skinner Sturr's anonymous Richmond, or stories in the life of a Bow Street Officer is from 1827; another early full-length short story in the genre is The Rector of Veilbye by Danish author Steen Steensen Blicher, published in 1829. A further example of crime detection can be found in Letitia Elizabeth Landon's story The Knife, published in 1832, although here the truth remains in doubt at the end.

Better known are the earlier dark works of Edgar Allan Poe.^[9] His brilliant and eccentric detective C. Auguste Dupin, a forerunner of Arthur Conan Doyle's Sherlock Holmes, appeared in works such as "The Murders in the Rue Morgue" (1841), "The Mystery of Marie Rogêt" (1842), and "The Purloined Letter" (1844). With his Dupin stories, Poe provided the framework for the classic detective story. The detective's unnamed companion is the narrator of the stories and a prototype for the character of Dr. Watson in later Sherlock Holmes stories.^[10]

Wilkie Collins' epistolary novel The Woman in White was published in 1860, while The Moonstone (1868) is often thought to be his masterpiece. French author Émile Gaboriau's Monsieur Lecoq (1868) laid the groundwork for the methodical, scientifically minded detective.

The evolution of locked-room mysteries was one of the landmarks in the history of crime fiction. The Sherlock Holmes mysteries of Doyle's are said to have been singularly responsible for the huge popularity of this genre. A precursor was Paul Féval, whose series Les Habits Noirs (1862–67) features Scotland Yard detectives and criminal conspiracies. The best-selling crime novel of the 19th century was Fergus Hume's The Mystery of a Hansom Cab (1886), set in Melbourne, Australia.

The evolution of the print mass media in the United Kingdom and the United States in the latter half of the 19th century was crucial in popularising crime fiction and related genres. Literary 'variety' magazines, such as Strand, McClure's, and Harper's, quickly became central to the overall structure and function of popular fiction in society, providing a mass-produced medium that offered cheap, illustrated publications that were essentially disposable.

Like the works of many other important fiction writers of his day—e.g. Wilkie Collins and Charles Dickens—Arthur Conan Doyle's Sherlock Holmes stories first appeared in serial form in the monthly Strand in the United Kingdom. The series quickly attracted a wide and passionate following on both sides of the Atlantic, and when Doyle killed off Holmes in "The Final Problem", the public outcry was so great, and the publishing offers for more stories so attractive, that he was reluctantly forced to resurrect him.

In Italy, early translations of English and American stories and local works were published in cheap yellow covers, thus the genre was baptized with the term libri gialli or yellow books. The genre was outlawed by the Fascists during WWII, but exploded in popularity after the war, especially influenced by the American hard-boiled school of crime fiction. A group of mainstream Italian writers emerged, who used the detective format to create an antidetective or postmodern novel in which the detectives are imperfect, the crimes are usually unsolved, and clues are left for the reader to decipher. Famous writers include Leonardo Sciascia, Umberto Eco, and Carlo Emilio Gadda.^[11]

In Spain, The Nail and Other Tales of Mystery and Crime was published by Pedro Antonio de Alarcón in 1853. Crime fiction in Spain (also curtailed in Francoist Spain) took on some special characteristics that reflected the culture of the country. The Spanish writers emphasized the corruption and ineptitude of the police, and depicted the authorities and the wealthy in very negative terms.^[11]

In China, modern crime fiction was first developed from translations of foreign works from the 1890s.^[12] Cheng Xiaoqing, considered the "Grand Master" of 20th-century Chinese detective fiction, translated Sherlock Holmes into classical and vernacular Chinese. In the late 1910s, Cheng began writing his own detective fiction series, Sherlock in Shanghai, mimicking Conan Doyle's style, but relating better to a Chinese audience.^[13] During the Mao era, crime fiction was suppressed and mainly Soviet-styled and anticapitalist. In the post-Mao era, crime fiction in China focused on corruption and harsh living conditions during the Mao era (such as the Cultural Revolution).^[11]

It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib, from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH). The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph Al-Mansur founded the city of Baghdad, near the ancient Babylonian capital city of Babylon. Baghdad became the center of science, culture and invention in what became known as the Golden Age of Islam. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning".

Plot twist

Plot twist

A plot twist is a literary technique that introduces a radical change in the direction or expected outcome of the plot in a work of fiction. When it happens near the end of a story, it is known as a twist or surprise ending. It may change the audience's perception of the preceding events, or introduce a new conflict that places it in a different context. A plot twist may be foreshadowed, to prepare the audience to accept it, but it usually comes with some element of surprise. There are a variety of methods used to execute a plot twist, such as withholding information from the audience, or misleading them with ambiguous or false information. Not every plot has a twist, but some have multiple lesser ones, and some are defined by a single major twist.

Detective fiction

Detective fiction is a subgenre of crime fiction and mystery fiction in which an investigator or a detective—whether professional, amateur or retired—investigates a crime, often murder. The detective genre began around the same time as speculative fiction and other genre fiction in the mid-nineteenth century and has remained extremely popular, particularly in novels. Some of the most famous heroes of detective fiction include C. Auguste Dupin, Sherlock Holmes, and Hercule Poirot. Juvenile stories featuring The Hardy Boys, Nancy Drew, and The Boxcar Children have also remained in print for several decades.

• The historical whodunit is also a subgenre of historical fiction. The setting of the story and the crime have some historical significance.
• The locked-room mystery is a specialized kind of a whodunit in which the crime is committed under apparently impossible circumstances, such as a locked room, which no intruder could have entered or left.
• The American hardboiled school is distinguished by the unsentimental portrayal of sex and violence; the sleuth usually also confronts danger and engages in violence.
• The police procedural is a story in which the detective is a member of the police, thus the activities of a police force are usually convincingly depicted.
• Forensic crime fiction is similar to the police procedural. The investigator whom the reader follows is usually a medical examiner or pathologist; they must use the forensic evidence left on the body and at the crime scene to catch the killer. This subgenre was first introduced by Patricia Cornwell.

Pseudonymous authors

In the history of crime fiction, some authors have been reluctant to publish their novels under their real names. More recently, some publish pseudonymously because of the belief that since the large booksellers are aware of their historical sales figures, and command a certain degree of influence over publishers, the only way to "break out" of their current advance numbers is to publish as someone with no track record.

In the late 1930s and 1940s, British County Court Judge Arthur Alexander Gordon Clark (1900–1958) published a number of detective novels under the alias Cyril Hare, in which he made use of his profoundly extensive knowledge of the English legal system. When he was still young and unknown, award-winning British novelist Julian Barnes (born 1946) published some crime novels under the alias Dan Kavanagh. Other authors take delight in cherishing their alter egos; Ruth Rendell (1930–2015) writes one sort of crime novels as Ruth Rendell and another type as Barbara Vine; John Dickson Carr also used the pseudonym Carter Dickson. Author Evan Hunter (which itself was a pseudonym) wrote his crime fiction under the name of Ed McBain.

Cozy mystery

Cozy mystery

Cozy mysteries, also referred to as "cozies", are a subgenre of crime fiction in which sex and violence occur off stage, the detective is an amateur sleuth, and the crime and detection take place in a small, socially intimate community. Cozies thus stand in contrast to hardboiled fiction, in which more violence and explicit sexuality are central to the plot. The term "cozy" was first coined in the late 20th century when various writers produced work in an attempt to re-create the Golden Age of Detective Fiction.

Historical fiction

Historical fiction

Historical fiction is a literary genre in which the plot takes place in a setting related to the past events, but is fictional. Although the term is commonly used as a synonym for historical fiction literature, it can also be applied to other types of narrative, including theatre, opera, cinema, and television, as well as video games and graphic novels.

Locked-room mystery

Locked-room mystery

The "locked-room" or "impossible crime" mystery is a type of crime seen in crime and detective fiction. The crime in question, typically murder, is committed in circumstances under which it appeared impossible for the perpetrator to enter the crime scene, commit the crime, and leave undetected. The crime in question typically involves a situation whereby an intruder could not have left; for example the original literal "locked room": a murder victim found in a windowless room locked from the inside at the time of discovery. Following other conventions of classic detective fiction, the reader is normally presented with the puzzle and all of the clues, and is encouraged to solve the mystery before the solution is revealed in a dramatic climax.

Hardboiled

Hardboiled

Hardboiled fiction is a literary genre that shares some of its characters and settings with crime fiction. The genre's typical protagonist is a detective who battles the violence of organized crime that flourished during Prohibition (1920–1933) and its aftermath, while dealing with a legal system that has become as corrupt as the organized crime itself. Rendered cynical by this cycle of violence, the detectives of hardboiled fiction are often antiheroes. Notable hardboiled detectives include Dick Tracy, Philip Marlowe, Mike Hammer, Sam Spade, Lew Archer, Slam Bradley, and The Continental Op.

Legal thriller

Legal thriller

The legal thriller genre is a type of crime fiction genre that focuses on the proceedings of the investigation, with particular reference to the impacts on courtroom proceedings and the lives of characters.

Espionage

Espionage

Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence). A person who commits espionage is called an espionage agent or spy. Any individual or spy ring, in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law.

Intelligence agency

Intelligence agency

An intelligence agency is a government agency responsible for the collection, analysis, and exploitation of information in support of law enforcement, national security, military, public safety, and foreign policy objectives.

Caper story

Caper story

The caper story is a subgenre of crime fiction. The typical caper story involves one or more crimes perpetrated by the main characters in full view of the reader. The actions of police or detectives attempting to prevent or solve the crimes may also be chronicled, but are not the main focus of the story.

Parody

Parody

A parody, also known as a spoof, a satire, a send-up, a take-off, a lampoon, a play on (something), or a caricature, is a creative work designed to imitate, comment on, and/or mock its subject by means of satiric or ironic imitation. Often its subject is an original work or some aspect of it, but a parody can also be about a real-life person, event, or movement. Literary scholar Professor Simon Dentith defines parody as "any cultural practice which provides a relatively polemical allusive imitation of another cultural production or practice". The literary theorist Linda Hutcheon said "parody ... is imitation, not always at the expense of the parodied text." Parody may be found in art or culture, including literature, music, theater, television and film, animation, and gaming. Some parody is practiced in theater.

Cyril Hare

Cyril Hare

Alfred Alexander Gordon Clark was an English judge and crime writer under the pseudonym Cyril Hare.

Novelist

Novelist

A novelist is an author or writer of novels, though often novelists also write in other genres of both fiction and non-fiction. Some novelists are professional novelists, thus make a living writing novels and other fiction, while others aspire to support themselves in this way or write as an avocation. Most novelists struggle to have their debut novel published, but once published they often continue to be published, although very few become literary celebrities, thus gaining prestige or a considerable income from their work.

Quality

As with any other entity, quality of a crime fiction book is not in any meaningful proportion to its availability. Some of the crime novels generally regarded as the finest, including those regularly chosen by experts as belonging to the best 100 crime novels ever written (see bibliography), have been out of print since their first publication, which often dates back to the 1920s or '30s. The bulk of books that can be found today on the shelves labelled "Crime" consists of recent first publications usually no older than a few years.

Classics and bestsellers

Furthermore, only a select few authors have achieved the status of "classics" for their published works. A classic is any text that can be received and accepted universally, because they transcend context. A popular, well-known example is Agatha Christie, whose texts, originally published between 1920 and her death in 1976, are available in UK and US editions in all English-speaking nations. Christie's works, particularly featuring detectives Hercule Poirot or Miss Jane Marple, have given her the title the Queen of Crime, and made her one of the most important and innovative writers in the development of the genre. Her most famous novels include Murder on the Orient Express (1934), Death on the Nile (1937), and the world's best-selling mystery And Then There Were None (1939).^[15]

Other less successful, contemporary authors who are still writing have seen reprints of their earlier works, due to current overwhelming popularity of crime fiction texts among audiences. One example is Val McDermid, whose first book appeared as far back as 1987; another is Florida-based author Carl Hiaasen, who has been publishing books since 1981, all of which are readily available.

Revivals

From time to time, publishing houses decide, for commercial purposes, to revive long-forgotten authors, and reprint one or two of their more commercially successful novels. Apart from Penguin Books, which for this purpose have resorted to their old green cover and dug out some of their vintage authors. Pan started a series in 1999 entitled "Pan Classic Crime", which includes a handful of novels by Eric Ambler, but also American Hillary Waugh's Last Seen Wearing .... In 2000, Edinburgh-based Canongate Books started a series called "Canongate Crime Classics" —both whodunnits and roman noir about amnesia and insanity—and other novels. However, books brought out by smaller publishers such as Canongate Books are usually not stocked by the larger bookshops and overseas booksellers. The British Library has also (since 2012) starting republishing "lost" crime classics, with the collection referred to on their website as "British Library Crime Classics series".

Sometimes, older crime novels are revived by screenwriters and directors rather than publishing houses. In many such cases, publishers then follow suit and release a so-called "film tie-in" edition showing a still from the movie on the front cover and the film credits on the back cover of the book—yet another marketing strategy aimed at those cinemagoers who may want to do both: first read the book and then watch the film (or vice versa). Recent examples include Patricia Highsmith's The Talented Mr. Ripley (originally published in 1955), Ira Levin's Sliver (1991), with the cover photograph depicting a steamy sex scene between Sharon Stone and William Baldwin straight from the 1993 movie, and again, Bret Easton Ellis's American Psycho (1991). Bloomsbury Publishing PLC, though, have launched what they call "Bloomsbury Film Classics"—a series of original novels on which feature films were based. This series includes, for example, Ethel Lina White's novel The Wheel Spins (1936), which Alfred Hitchcock—before he went to Hollywood—turned into a much-loved movie entitled The Lady Vanishes (1938), and Ira Levin's (born 1929) science-fiction thriller The Boys from Brazil (1976), which was filmed in 1978.

Older novels can often be retrieved from the ever-growing Project Gutenberg database.

The US edition was released in January 1940 with the title And Then There Were None, taken from the last five words of the song. Successive American reprints and adaptations use that title, though Pocket Books paperbacks used the title Ten Little Indians between 1964 and 1986. UK editions continued to use the original title until 1985.

Amnesia

Amnesia

Amnesia is a deficit in memory caused by brain damage or disease, but it can also be caused temporarily by the use of various sedatives and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that was caused. There are two main types of amnesia: retrograde amnesia and anterograde amnesia. Retrograde amnesia is the inability to retrieve information that was acquired before a particular date, usually the date of an accident or operation. In some cases the memory loss can extend back decades, while in others the person may lose only a few months of memory. Anterograde amnesia is the inability to transfer new information from the short-term store into the long-term store. People with anterograde amnesia cannot remember things for long periods of time. These two types are not mutually exclusive; both can occur simultaneously.

Insanity

Insanity

Insanity, madness, lunacy, and craziness are behaviors performed by certain abnormal mental or behavioral patterns. Insanity can manifest as violations of societal norms, including a person or persons becoming a danger to themselves or to other people. Conceptually, mental insanity also is associated with the biological phenomenon of contagion as in the case of copycat suicides. In contemporary usage, the term insanity is an informal, un-scientific term denoting "mental instability"; thus, the term insanity defense is the legal definition of mental instability. In medicine, the general term psychosis is used to include the presence of delusions and/or hallucinations in a patient; and psychiatric illness is "psychopathology", not mental insanity.
