Lizzie (1957).

Five months before the appearance of The Three Faces of Eve was the release of Lizzie (1957), in which a bewildered Elizabeth Richmond (played by Eleanor Parker) receives threatening letters from a stranger named Lizzie. The film (also starring Richard Boone and Joan Blondell, as well as Johnny Mathis singing "It's Not for Me to Say") was based on The Bird's Nest (1954) by Shirley Jackson (The Haunting of Hill House, "The Lottery," etc.).
