Dennis Yeats Wheatley (8 January 1897 – 10 November 1977) was a British writer whose prolific output of thrillers and occult novels made him one of the world's best-selling authors from the 1930s through the 1960s. His Gregory Sallust series was one of the main inspirations for Ian Fleming's James Bond stories.

Early life
Wheatley was born at 10 Raleigh Gardens, Brixton Hill, London to Albert David and Florence Elizabeth Harriet (Baker) Wheatley. He was the eldest of three children, his father owned Wheatley & Son, a wine business in Mayfair, London. Dennis admitted to having little aptitude for schooling and was later expelled from Dulwich College for allegedly forming a "secret society", as he mentions in his introduction to The Devil Rides Out. Soon after his expulsion, Wheatley became a British Merchant Navy officer cadet on the training ship HMS Worcester.

Military service
Wheatley was commissioned as a 2nd Lieutenant into the Royal Field Artillery during the First World War, receiving his basic training at Biscot Camp in Luton. He was assigned to the City of London Brigade and the 36th (Ulster) Division. Dennis was gassed in a chlorine attack during Passchendaele and was invalided out, having served in Flanders, on the Ypres Salient, and in France at Cambrai and Saint-Quentin.

In 1919 he took over management of the family's wine business. In 1931, however, after business had declined because of 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 led to his working with planning staffs for the War Office. He wrote numerous papers for them, including suggestions for dealing with a possible Nazi 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 received a direct commission in the JP Service as a Wing Commander, RAFVR, and took part in the plans for the Normandy invasions. After the war Wheatley was awarded the U.S. Bronze Star for his role in the Second World War.

Writing career

His first book, Three Inquisitive People, was not published when completed, but came out later, in 1940. However, his next novel made quite a splash. Called The Forbidden Territory, it was an immediate success when issued by Hutchinson in 1933, being reprinted seven times in seven weeks. After finishing The Fabulous Valley, Wheatley decided to use the theme of black magic for his next book. He wrote: "The fact that I had read extensively about ancient religions gave me some useful background, but I required up-to-date information about occult circles in this country. My friend, Tom Driberg, who then lived in a mews flat just behind us in Queen's Gate, proved most helpful. He introduced me to Aleister Crowley, the Reverend Montague Summers and Rollo Ahmed." 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 - making them into fantasy and specifically contemporary fantasy. He came to be considered an authority on Satanism, the practice of exorcism, and black magic, toward all of which he expressed hostility. During his study of the paranormal, though, he joined the Ghost Club.

In many of his works, Wheatley wove in interactions between his characters and actual historical events and individuals. For example, in the Roger Brook series the main character involves himself with Napoleon and Joséphine whilst spying for Prime Minister William Pitt the Younger. Similarly, in the Gregory Sallust series, Sallust shares an evening meal with Hermann Göring. In "They Used Dark Forces", the penultimate book of the Sallust series, Göring gets a surprisingly positive depiction as an honourable man who disliked the systematic killing of the Jews (though not actually doing anything to stop it) and who wanted to end the war when realizing that Germany was doomed to lose it; Göring is contrasted with Goebbels, who according to Wheatley "was on the extreme left" and "took seriously the Socialist part of National Socialism".  

During the 1930s, Wheatley conceived a series of mysteries, presented as case files, including 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 'Crime Dossiers' were published: Murder Off Miami, Who Killed Robert Prentice?, The Malinsay Massacre, and Herewith The Clues!.

Wheatley also devised a number of board games including Invasion (1938), Blockade (1939), and Alibi (April 1953).

In the 1960s, Hutchinson was selling a million copies of his books per year, and most of his titles were kept available in hardcover. A few of his books were made into films by Hammer, of which the best known is The Devil Rides Out (book 1934, film 1968). Wheatley also wrote non-fiction works, including an account of the Russian Revolution, a life of King Charles II of England, and several autobiographical volumes.

He edited several collections of short stories, and from 1974 to 1977 he supervised a series of 45 paperback reprints for the British publisher Sphere with the heading "The Dennis Wheatley Library of the Occult", selecting the titles and writing short introductions for each book. These included both occult-themed novels by the likes of Bram Stoker and Aleister Crowley (with whom he once shared a lunch) and non-fiction works on magic, occultism, and divination by authors such as the Theosophist H. P. Blavatsky, the historian Maurice Magre, the magician Isaac Bonewits, and the palm-reader Cheiro.

Two weeks before his death in November 1977, Wheatley received conditional absolution from his old friend Cyril 'Bobby' Eastaugh, the Bishop of Peterborough. He was cremated at Tooting and his ashes interred at the South Cemetery section of Brookwood Cemetery, under a tall tree near the entrance. He is also commemorated on the Baker/Yeats family monument at West Norwood Cemetery.

His estate library was sold in a catalogue sale by Basil Blackwell's in 1979. It suggested a well-read individual with wide-ranging interests, particularly with respect to historical fiction and Europe.

His grandson Dominic Wheatley became one of the co-founders of the software house Domark, which published a number of titles in the 1980s and 1990s.

Politics
Wheatley's work reflects his conservative worldview. His protagonists are generally supporters of the monarchy, the British Empire and the class system, and many of his villains are villainous because they attack these ideas. Wheatley was an opponent of Nazism and Communism, believing the latter to be controlled by Satanic power.

Letter to Posterity
During the winter of 1947, Wheatley penned 'A Letter to Posterity' and buried it in an urn at his country home. The letter was intended to be discovered some time in the future (it was found in 1969, when the house was demolished for redevelopment of the property). He predicted in it that the socialist reforms, which were introduced by the post-war government, would result inevitably in the abolition of the monarchy, the "pampering" of a "lazy" working class and a national bankruptcy. He advised both passive and active resistance to the resulting "tyranny", including "ambushing and killing of unjust tyrannous officials".
Employers are now no longer allowed to run their businesses as they think best but have become the bond slaves of socialist state planning. The school leaving age has been put up to 16, and a 5 day working week has been instituted in the mines, the railways and many other industries.

The doctrine of ensuring every child a good start in life and equal opportunities is fair and right, but the intelligent and the hardworking will always rise above the rest, and it is not a practical proposition that the few should be expected to devote their lives exclusively to making things easy for the majority. In time, such a system is bound to undermine the vigour of the race.

Posthumous publication
From 1972 to 1977 (the year of his death), 52 of Dennis Wheatley's novels were offered in a uniform hardcover set by Heron Books UK. (This was in addition to Hutchinson's own "Lymington" library edition, published from 1961 to 1979.) Having brought each of his major fictional series to a close with the final Roger Brook novel, Wheatley then turned to his memoirs. These were announced as five volumes, but never completed, and were eventually published as three books, the (fourth) volume concerning the Second World War issued as a separate title. His availability and influence declined following his death, partly owing to difficulties of reprinting his works because of copyright problems.

In 1998 Justerini & Brooks celebrated their upcoming 250th anniversary by revising his last work about their house, "The Eight Ages of Justerini's" (1965) and re-issuing it as "The Nine Ages of Justerini's". The revision by Susan Keevil brought the history up to date.

Wheatley's literary estate was acquired by media company Chorion in April 2008, and several titles were reissued in Wordsworth paperback editions. A new hardcover omnibus of Black Magic novels was released by Prion in 2011.

When Chorion encountered financial problems in 2012, the Rights House and PFD acquired four crime estates from them, including the Wheatley titles. PFD hoped to broker new series for TV and radio, and a move to digital publishing.

In October 2013, Bloomsbury Reader began republishing 56 of his titles; many of these will be edited and abridged. However, many of them will also have new introductions evaluating Wheatley's work, including some written by his grandson, Dominic Wheatley. These are to be available in both printed format and as ebooks.

In fiction
In Stephen Volk's novella Netherwood, part of Volk's 2018 book The Dark Masters Trilogy, set in 1947, a fictional version of Wheatley is involved in black magic by Aleister Crowley.
