Ronald Lewis in Scream of Fear (1961)

The Film

After the death of her closest friend, wheelchair bound Penny accepts an invitation to return to the French Riviera estate of her estranged father. When she arrives, however, her father is suspiciously absent, and her stepmother, the local doctor, and the family chauffeur seem hard pressed to believe her when she claims his corpse was sitting in the empty summer house.—IMDB Synopsis

I wouldn't mind being driven insane by my chauffeur if he's always walking around in the skimpiest swim suit, just saying.
