Baroness Carla Jenssen shot to notoriety around the end of the 1920s with the publication of an autobiographical account of exploits in espionage and cosmopolitan High Society across the world. After the success of I Spy! The Sensational Disclosures of a British Secret Agent she embarked on a speaking tour of the United States and ended up selling her story to Hollywood. In 1934 she sued RKO Studios for making an unauthorised film out of her “literary composition.”
