Much of what is known about Elliot's life in France is recorded in her memoirs, "Journal of my life during the French Revolution." Although there are a number of inconsistencies in her account, her work has become one of the best-known English-language accounts of The Terror, documenting the movements of the Duke of Orleans and those within his aristocratic Jacobin circle at the Palais-Royal. During her life in Paris, Elliott witnessed the horror of the September massacres and the body of the Princess de Lamballe carried through the streets. Although Elliott was an associate of the Duke of Orleans (who later took the name Philippe Égalité), her royalist sympathies soon became widely known throughout her district, and her home was frequently searched. It has been recently shown that Elliott was trafficking correspondence on behalf of the British government and assisting in the transportation of messages between Paris and members of the exiled French court in Coblenz and in Belgium.
