Donald MacKenzie 1908-1993, was a Canadian criminal who later became an author of detective fiction. He was born on August 11, 1908 in Toronto, Ontario, Canada. He was educated in England, Canada, and Switzerland. From approximately 1930 to 1948, MacKenzie led a life of crime as a con-man, share-pusher, and finally a burglar. He started his literary career while serving time in jail, eventually publishing several crime, detective, and thriller novels. His first publications were two autobiographies detailing his previous life as a criminal: Fugitives/Occupation: Thief (1955) and Gentlemen at Crime (1956). MacKenzie's first novel Nowhere to Go was also published in 1956. His subsequent novels focused on the exploits of criminals (the Macbeth Bain series and the Henry Chalice/Crying Eddie series) or the adventures of Detective Inspector John Raven. MacKenzie continued to write until his death, publishing the final novel in the John Raven series, The Sixth Deadly Sin, in 1993.
