Overcome with grief at her husband's death, Lady Franklin, an eligible young widow, unburdens herself to Leadbitter - a gallant, hard-bitten ex-soldier who has invested his savings in the car he drives for hire - as he takes her on a series of journeys. He in turn beguiles her with stories of his non-existent wife and children, drawing her out of her self-absorption and weaving a dream-life with Lady Franklin at its heart. Half-hoping to make his dream come true, Leadbitter takes a bold, not to say reckless, step which costs him dearly, and brings these characters' tangled story to a dramatic and unexpected conclusion.
