Sheldon B. Cole was one of many pseudonyms used by prolific Australian writer Desmond Robert Dunn (6 November 1929-5 May 2003). In addition to four crime novels published under his own name, Des was a tireless western writer whose career spanned more than fifty years and well in excess of 400 oaters. These quick-moving, vivid and always compelling stories appeared under such pen-names as Shad Denver, Gunn Halliday, Adam Brady, Brett Iverson, Matt Cregan, Walt Renwick and Morgan Culp. He is also said to have written a number of the ever-popular Larry Kent P.I. novels, but at this late date author attribution is almost impossible. He married and divorced twice, and had three children. He died at the age of 73 in Brisbane, Queensland.
