Herman Cyril McNeile MC (28 September 1888 - 14 August 1937) was a British author, who published under the pen name "Sapper." He was one of the most successful British popular authors of the Interwar period; his principal character was Bulldog Drummond. He is mainly remembered as the author of the ten Bulldog Drummond books, the first of which was published in 1920. These stridently anti-Communist spy thrillers brought him public recognition and considerable financial success. Mufti was McNeile's first book to be published (1919) - a year before his Bulldog Drummond series started and examines the social conditions as well as the evolving relationships between men and women in the last 3 months of the First World War.
