D. M. Devine (1920-1980) was the Scottish author of 13 crime novels, and acknowledged as a master of the classic detective story.

His first book, My Brother’s Killer, was nominated by Agatha Christie as winner of the Dons’ Detective Novel Competition held by Collins Crime Club in 1961. Unfortunately, as Devine was a university administrator rather than a Don, the novel was disqualified – nevertheless, the contest kick-started his career as Collins published him in the Crime Club series. The quality of his subsequent novels ensured that he remained a firm favourite of Agatha Christie.
