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.
