Howdunnit An important variation on the whodunit is the
inverted detective story (also referred to as a
howcatchem or
howdunnit) in which the guilty party and the crime are openly revealed to the reader/audience and the story follows the investigator's efforts to find out the truth while the criminal attempts to prevent it. The
Columbo TV series is the classic example of this kind of detective story (
Law & Order: Criminal Intent and
The Streets of San Francisco also fit into this genre). This tradition dates back to the inverted detective stories of
R Austin Freeman, and reached an apotheosis of sorts in
Malice Aforethought written by Francis Iles (a pseudonym of
Anthony Berkeley). In the same vein is Iles's
Before the Fact (1932), which became the
Hitchcock movie
Suspicion. Successors of the psychological suspense novel include
Patricia Highsmith's
This Sweet Sickness (1960),
Simon Brett's
A Shock to the System (1984), and
Stephen Dobyns's
The Church of Dead Girls (1997).
Whydunit A whydunit is a story in which the central mystery is the motive, rather than the perpetrator. A notable example is
The Secret History by
Donna Tartt, in which the killers and the circumstances of the murder are revealed on the first page.
Parody and spoof In addition to standard humor,
parody, spoof, and
pastiche have had a long tradition within the field of crime fiction. Examples of pastiche are the
Sherlock Holmes stories written by
John Dickson Carr, and hundreds of similar works by such authors as
E. B. Greenwood. As for parody, the first Sherlock Holmes spoofs appeared shortly after
Conan Doyle published his first stories. Similarly, there have been innumerable
Agatha Christie send-ups. The idea is to exaggerate and mock the most noticeable features of the original and, by doing so, amuse especially those readers who are also familiar with that original. There are also "reversal" mysteries, in which the conventional structure is deliberately inverted. One of the earliest examples of this is ''
Trent's Last Case'' (1914) by
E. C. Bentley (1875–1956). Trent, a very able amateur detective, investigates the murder of Sigsbee Manderson. He finds many important clues, exposes several false clues, and compiles a seemingly unassailable case against a suspect. He then learns that that suspect cannot be a murderer, and that while he found nearly all of the truth, his conclusion is wrong. Then, at the end of the novel, another character tells Trent that he always knew the other suspect was innocent, because "I shot Manderson myself." These are Trent's final words to the killer: Another example of a spoof, which at the same time shows that the borderline between serious mystery and its parody is necessarily blurred, is U.S. mystery writer
Lawrence Block's novel
The Burglar in the Library (1997). The burglar of the title is Bernie Rhodenbarr, who has booked a weekend at an English-style country house just to steal a signed, and therefore very valuable, first edition of
Chandler's
The Big Sleep, which he knows has been sitting there on one of the shelves for more than half a century. Alas, immediately after his arrival a dead body turns up in the library, the room is sealed off, and Rhodenbarr has to track down the murderer before he can enter the library again and start hunting for the precious book.
Murder by Death is
Neil Simon's spoof of many of the best-known whodunit sleuths and their
sidekicks. In the 1976 film,
Sam Spade (from
The Maltese Falcon) becomes Sam Diamond, Hercule Poirot becomes Milo Perrier, and so on. Since most homicides are committed by people with whom the victim is acquainted or related, a whodunit case is usually more difficult to solve. ==See also==
