George Norman Douglas (8 December 1868 - 7 February 1952) was a British writer, now best known for his 1917 novel South Wind and remains Douglas's most famous work. Douglas was brought up mainly at Tilquhillie, Deeside, his paternal home. He was educated at Yarlet Hall and Uppingham School in England, and then at a grammar school in Karlsruhe. Douglas's paternal grandfather was the 14th Laird of Tilquhillie. Douglas's maternal great-grandfather was General James Ochoncar Forbes, 17th Lord Forbes. South Wind is set on an imaginary island called Nepenthe, located off the coast of Italy in the Tyrrhenian Sea, a thinly fictionalized description of Capri's residents and visitors. The novel's discussion of moral and sexual issues caused considerable debate. In Dorothy Sayers's 1926 detective novel Clouds of Witness, Lord Peter Wimsey goes through the possessions of a murdered man - a young British man living in Paris, whose morality had been put in question. Finding a copy of South Wind Wimsey remarks "Our young friend works out very true to type."
