Georgette Heyer was an English novelist and short-story writer, in both the Regency romance and detective fiction genres. Her writing career began in 1921, when she turned a story conceived for her ailing younger brother into the novel The Black Moth. In 1925 Heyer married George Ronald Rougier, a mining engineer. The couple spent several years living in Tanganyika Territory and Macedonia before returning to England in 1929. After her novel These Old Shades became popular despite its release during the General Strike, Heyer determined that publicity was not necessary for good sales. For the rest of her life she refused to grant interviews, telling a friend: "My private life concerns no one but myself and my family."

Regency romances are a subgenre of romance novels set during the period of the British Regency (1811–1820) or early 19th century. Rather than simply being versions of contemporary romance stories transported to a historical setting, Regency romances are a distinct genre with their own plot and stylistic conventions. These derive not so much from the 19th-century contemporary works of Jane Austen, but rather from Georgette Heyer, who wrote over two dozen novels set in the Regency starting in 1935 until her death in 1974, and from the fiction genre known as the novel of manners. In particular, the more traditional Regencies feature a great deal of intelligent, fast-paced dialogue between the protagonists and very little explicit sex or discussion of sex.
