The Man In The Dark

James Longford, a wealthy former racing car driver with vision loss from an accident several years before, hires 26-year-old Marda Mayne as companion to his newly-orphaned 17-year-old American ward Shirley.

His main concern is to avoid being troubled so he can continue to live in self-imposed isolation, but as plucky, practical Marda and flirtatious, kind-hearted Shirley take his intimidating household staff in hand (and find an unexpected ally in that surly butler), they also begin to revive James' interest in life.

The trio will have to brace themselves, however, when his self-absorbed, manipulative sister Vera-who sees his fortune as practically already hers-announces a visit.
