Woman In White, The (1948) - Waiting For That Supreme Moment

Sensible cousin Marian (Alexis Smith), returned to Fairlie House, is concerned at the behavior of her cousin Laura (Eleanor Parker) after her marriage to Percival (John Emery), who tangles with Count Fosco (Sydney Greenstreet), whose wife (Agnes Moorehead) seems even more weird, in The Woman In White, 1948.
