Wensley Clarkson, a British tabloid writer, is the author of more than two dozen true-crime novels and quickie celebrity biographies. In his tell-all book, Death at Every Stop: The True Story of Alleged Gay Serial Killer Andrew Cunanan, Clarkson takes the reader into the mind of the playboy who murdered Italian fashion designer Gianni Versace. Some of Clarkson's other true-crime novels include Whatever Mother Says, the shocking true story of a woman who was arrested in 1993 for the torture murders of her two daughters. Doctors of Death is the chilling true tales of psychopathic physicians; and An Eye for An Eye is the story of a woman out for revenge after the murder of her daughter, which was turned into a feature film starring Sally Fields. Clarkson's unauthorized biographies include exposes on Mel Gibson, Tom Cruise, John Travolta, and Quentin Tarantino.
Nigel McCrery was a policeman but left to study History and went on to work for the BBC's drama department. Credits he lists are the award-winning All The King's Men, Silent Witness and New Tricks. He has written several crime novels, including the Detective Inspector Lapslie series.
