From Wikipedia: "Dennis Yates Wheatley (8 January 1897 10 November 1977) was an English author whose prolific output of thrillers and occult novels made him one of the world's best-selling writers from the 1930s through the 1960s. His Gregory Sallust series was one of the main inspirations for Ian Fleming's James Bond stories. Dennis Wheatley was born in South London to Albert David and Florence Elizabeth Harriet Wheatley (nee Baker). He was the eldest of three children of a family who were the owners of Wheatley & Son of Mayfair, a wine business. He admitted to little aptitude for schooling and was expelled from Dulwich College for allegedly forming a Secret society ( this is mentioned in the writers introduction of The Devil Rides Out. Soon after his expulsion, Wheatley became a British Merchant Navy officer cadet on the training ship HMS Worcester. Wheatley was commissioned as 2nd Lieutenant into the Royal Field Artillery during the First World War and served in France with the City of London Brigade and the 36th (Ulster) Division. He was gassed in a chlorine attack at Passchendaele and invalided after service in Flanders, on the Ypres Salient, and in France at Cambrai and St. Quentin. In 1919 he assumed management of the family wine merchant business but in 1931, after a decline in business due to the Great Depression, he sold the firm and began writing. During the Second World War, Wheatley was a member of the London Controlling Section, which secretly coordinated strategic military deception and cover plans. His literary talents gained him employment with planning staffs for the War Office. He wrote numerous papers for the War Office, including suggestions for dealing with a German invasion of Britain (recounted in his works Stranger than Fiction and The Deception Planners). The most famous of his submissions to the Joint Planning Staff of the war cabinet was on "Total War". He was given a commission directly into the JP Service as Wing Commander, RAFVR and took part in advance planning for the Normandy invasions. In 1946, Wheatley was awarded the U.S. Bronze Star for his part in the war effort. His first novel published, The Forbidden Territory, was an immediate success when issued by Hutchinson in 1933, being reprinted seven times in seven weeks. The release the next year of his occult story, The Devil Rides Out hailed by James Hilton as "the best thing of its kind since Dracula" cemented his reputation as "The Prince of Thriller Writers." Wheatley mainly wrote adventure novels, with many books in a series of linked works. Background themes included the French Revolution (the Roger Brook series), Satanism (the Duke de Richleau series), World War II (the Gregory Sallust series) and espionage (the Julian Day novels). Over time, each of his major series would include at least one book pitting the hero against some manifestation of the supernatural. He came to be considered an authority on this, satanism, the practice of exorcism, and black magic, to all of which he was hostile. During his study of the paranormal, though, he joined the Ghost Club. His writing is very descriptive and in many works he manages to involve his characters with actual historical events while meeting real people. For example, in the Roger Brook series the main character involves himself with Napoleon and Joséphine whilst being a spy for Prime Minister William Pitt the Younger. Similarly, in the Gregory Sallust series, Sallust shares an evening meal with Hermann Goering. During the 1930s, he conceived a series of mysteries, presented as case files, with testimonies, letters, and pieces of evidence such as hairs or pills. The reader had to inspect this evidence to solve the mystery before unsealing the last pages of the file, which gave the answer. Four of these.
