After her return to London in early 1937, David recognised that she was not going to be a success on the stage, and abandoned thoughts of a theatrical career. Later in the year she took a post as a junior assistant at the fashion house of Worth, where elegant young women from upper-class backgrounds were sought after as recruits. She found the subservience of retail work irksome, and resigned in early 1938. Over the next few months she spent time holidaying in the south of France and on Corsica, where she was greatly taken with the outgoing nature of the people she stayed with and the simple excellence of their food. After returning to London, and disenchanted with life there, she joined Cowan in buying a small boat—a yawl with an engine—with the intention of sailing it to Greece. They crossed the Channel in July 1939 and navigated the boat through the canal system of France to the Mediterranean coast.
