Dennis Wheatley (8 January 1897-10 November 1977) was a British writer born in London. His prolific output of stylish thrillers and occult novels made him one of the world's best-selling authors in the 1950s and 1960s.

He took part in the First World War but was gassed and invalided out. He took over the family wine making business but, following a decline in business, set about writing.

His first book, Three Inquisitive People, was not an immediate success; but a second book, The Forbidden Territory, was.

He wrote adventure stories, with many books in a series of linked works. His plots covered the French Revolution (Roger Brook Series), Satanism (Duc de Richleau), World War 2 (Gregory Sallust) and espionage (Julian Day).

Around the 1960s his publishers were selling 1 million copies of his books per year. A small number of his books were made into films by Hammer , of which the best known is The Devil Rides Out. His writing is very descriptive and in many works he manages to introduce his characters into real events while meeting real people. For example, in the Roger Brook series the main character involves himself with Napoleon, and Josephine whilst being a spy for the Prime Minister William Pitt. Similarly, in the Gregory Sallust series, Sallust shares an evening meal with Hermann Göring.

He also wrote non-fiction works, including accounts of the Russian Revolution and King Charles II, and his autobiography.

52 of Wheatley's novels were published in a set by Heron Books.
