John Creasey (September 17, 1908 - June 9, 1973) was born in Southfields, Surrey, England and died in New Hall, Bodenham, Salisbury Wiltshire, England. He was the seventh of nine children in a working class home. He became an English author of crime thrillers, published in excess of 600 books under 20+ different pseudonyms. He invented many famous characters who would appear in a whole series of novels. Probably the most famous of these is Gideon of Scotland Yard, the basis for the television program Gideon's Way but others include Department Z, Dr. Palfrey, The Toff, Inspector Roger West, and The Baron (which was also made into a television series). In 1962, Creasey won an Edgar Award for Best Novel, from the Mystery Writers of America, for Gideon's Fire, written under the pen name J. J. Marric. And in 1969 he was given the MWA's highest honor, the Grand Master Award.
Secret Errand is the first in John Creasey's series featuring Bruce Murdoch. It was originally published in 1939 under Creasey's pseudonym Norman Deane. The new and revised version was released many years later.
Secret Errand is a rip roaring spy/adventure story with some clever twists and turns. I would be interested in tracking down the rest of the Murdoch novels.
