Initially a play written by Christie in the late 1930s, the plot tells of a daughter's opposition to her mother's plan to remarry. Christie tried to interest Peter Saunders, later the producer of The Mousetrap in the play in 1950. He suggested amendments to update some of the references which were now twenty years old and tried the play out at the Theatre Royal, Bath where it opened on July 9, 1956 and ran for one week and eight performances. It was billed under the Westmacott name but the true identity of the author slipped out resulting in good attendance figures. Saunders however felt that it would not survive in the West End and Christie didn't pursue the matter further.
