 Recent additions to the subgenre of the whodunit include Simon Brett, the Thackery Phin novels of John Sladek, Lawrence Block's "The Burglar in the Library" (1997) (which is a spoof set in the present in an English-style country house), Kinky Friedman's "Road Kill" (1997), Ben Elton's "Dead Famous" (2001), and Gilbert Adair's "The Act of Roger Murgatroyd" (2006).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 movie series is the classic example of this kind of detective story ("" and "The Streets of San Francisco" also fit into this genre).
