Lady Possessed (1952)

In a London nursing home, Jean Wilson, a happily-married American woman, while in a state of semi-consciousness, hears Jimmy Del Palma angrily berate the hospital management for the out-dated treatment used on his wife who later dies. When she is well again, Jean rents the former home of Del Palma, a famous concert pianist, and his late wife. Not knowing why, she begins to fall in love with the absent man and on hearing about his wife's death, dreams of taking her place. Her dream comes close to becoming reality.
