Sapper (born Sept. 28, 1888, Bodmin, Cornwall, Eng.—died Aug. 14, 1937, West Chiltington, Sussex) was a British soldier and novelist who won immediate fame with his thriller Bull-Dog Drummond (1920), subtitled “The Adventures of a Demobilized Officer Who Found Peace Dull.” Sapper published numerous popular sequels, but none had the impact and merit of the original.
