Orczy's original play, The Scarlet Pimpernel, was produced and adapted by Julia Neilson and Fred Terry. It opened on 15 October 1903 at Nottingham's Theatre Royal and was not a success. Terry, however, had confidence in the play and, with a rewritten last act, took it to London's West End where it opened at the New Theatre on 5 January 1905. The premier of the London production was enthusiastically received by the audience, but critics considered the play 'old-fashioned.' In spite of negative reviews, the play became a popular success, running 122 performances and enjoying numerous revivals. The Scarlet Pimpernel became a favourite of London audiences, playing more than 2,000 performances and becoming one of the most popular shows staged in the United Kingdom.
The novel The Scarlet Pimpernel was published soon after the play opened and was an immediate success. Orczy gained a following of readers in Britain and throughout the world. The popularity of the novel encouraged her to write a number of sequels for her "reckless daredevil" over the next 35 years. The play was performed to great acclaim in France, Italy, Germany and Spain, while the novel was translated into 16 languages. Subsequently, the story has been adapted for television, film, a musical and other media.
The international success of The Scarlet Pimpernel allowed Orczy and her husband to live out their lives in luxury. Over the years, they lived on an estate in Kent, a bustling London home and an opulent villa in Monte Carlo. Orczy wrote in her autobiography, Links in the Chain of Life:
I have so often been asked the question: "But how did you come to think of The Scarlet Pimpernel?" And my answer has always been: "It was God's will that I should." And to you moderns, who perhaps do not believe as I do, I will say, "In the chain of my life, there were so many links, all of which tended towards bringing me to the fulfillment of my destiny."
