The Passionate Stranger1957

Judith Wynter is a happily married novelist whose romantic works are eagerly devoured by scores of female readers. When Carlo, a handsome young Italian chauffeur, arrives to work for Judith and her husband, a professor currently recovering from an attack of paralysis, he causes quite a flutter; when he then reads the manuscript of Judith's latest novel, he jumps to a rather unfortunate conclusion... and life in the Wynter household becomes very complicated indeed!
