The Triumph of the Scarlet Pimpernel, first published in 1922, is a book in the series about the Scarlet Pimpernel's adventures by Baroness Orczy. Again Orczy interweaves historic fact with fiction, this time through the real life figures of Thérésa Cabarrus, and Jean-Lambert Tallien; inserting the Scarlet Pimpernel as an instigator of the role Tallien played in the Thermidorian Reaction in July 1794.

Baroness Emma Magdolna Rozália Mária Jozefa Borbála "Emmuska" Orczy de Orci (/23 September 1865 12 November 1947) was a Hungarian-born British novelist, playwright, and artist of noble origin. She is most known for her series of novels featuring the Scarlet Pimpernel.In 1903, she and her husband wrote a play based on one of her short stories about an English aristocrat, Sir Percy Blakeney, Bart., who rescued French aristocrats from the French Revolution: The Scarlet Pimpernel.Orczy went on to write over a dozen sequels featuring Sir Percy Blakeney, his family, and the other members of the League of the Scarlet Pimpernel, of which the first, I Will Repay (1906), was the most popular. The last Pimpernel book, Mam'zelle Guillotine, was published in 1940. None of her three subsequent plays matched the success of The Scarlet Pimpernel. She also wrote popular mystery fiction and many adventure romances. Her Lady Molly of Scotland Yard was an early example of a female detective as the main character. Other popular detective stories featured The Old Man In the Corner, a sleuth who chiefly used logic to solve crimes.
