Susan becomes jealous when she discovers this mysterious woman, but when she confronts Jekyll, to explain the sudden appearance of his female alter ego, he calls her Mrs. Hyde, saying she is his widowed sister who has come to live with him. Howard, on the other hand, develops a lust for Mrs. Hyde.Dr. Jekyll soon finds that his serum requires a regular supply of female hormones to maintain its effect, necessitating the killing of young girls.
