Thriller I rented 8 years ago. Set on coast of Monaco or Italy. Alfred-hitch like film. An American woman staying in a villa awaiting her husband who is stuck in the U.S. To join her, befriends an American soldier. She invites h to dinner at her villa (?) where he aggressively tries to rape her. She kills him and hides his body in a trunk…a policeman is onto her.., in color early 60’s. Can’t think of the name!
