So Evil My Love

Onboard a ship traveling to Liverpool, England from the West Indies, Anglican missionary's widow Olivia Harwood (Ann Todd) is prevailed on to help nurse malarial patients on the lower decks. There she meets the suavely handsome Mark Bellis (Ray Milland), who has been taken ill. Despite Mark's vagueness about his life and past, the couple strike up a friendship. Fully recovered by the time the ship docks, Mark persuades Olivia to allow him to take up residence in the lodging house she has inherited from her late husband. He proceeds to work a smooth line of seduction on her, while still finding time to also use his charms on the more worldly and vulgar Kitty (Moira Lister).
