Georgette Heyer was an acclaimed English novelist and short-story writer, known for her significant contributions to both the Regency romance and detective fiction genres. She embarked on her writing career in 1921 with her debut novel The Black Moth, originally conceived as a story for her ailing younger brother.

In 1925, Heyer married George Ronald Rougier, a mining engineer. The couple lived in Tanganyika Territory and Macedonia before settling back in England in 1929. Heyer's novel These Old Shades gained popularity despite being released during the General Strike, leading her to conclude that her work could succeed without the need for publicity. Subsequently, she famously refused to give interviews, stating that her private life was her own concern.

Heyer is celebrated for establishing the historical romance genre, particularly the subgenre of Regency romance, drawing inspiration from Jane Austen. Her meticulous research and detailed notes on Regency life contributed to the authenticity of her work. While some critics found her novels overly detailed, others praised the depth and accuracy of her descriptions. Her historical novels, such as The Conqueror, demonstrate her commitment to historical accuracy.

From 1932 onwards, Heyer consistently published one romance and one thriller annually. Her husband often provided initial outlines for her detective stories, while Heyer's talent lay in fleshing out the characters and dialogue. Although her detective novels faced criticism for lacking originality, they were also lauded for their wit and intricate plotting.

Despite her success, Heyer faced challenges with tax authorities and alleged plagiarists. She avoided litigation against those she suspected of copying her work and sought ways to manage her tax liabilities. Ultimately, she formed a limited liability company to oversee the rights to her novels. In 1966, she sold the company and the rights to seventeen of her novels to Booker-McConnell.

Heyer continued to write until her death in 1974. At the time of her passing, forty-eight of her novels were still in print, including My Lord John, which was published posthumously.
