Despite these comments, the actors and the direction were both praised. The unnamed reviewer complained of the 'walking ciphers of the vicarage' and 'the rather thin theatrical excitement of first one, then another confession, both of which possibly cancel each other'.

Nobody, unhappily, has any good stage reason for living. In its issue of 15 December 1949, The Times gave an unenthusiastic review which began, 'Everyone has a motive for killing. The play enjoyed a run of 126 performances, closing on 1 April 1950. The director was Reginald Tate who also played the part of Lawrence Redding. The play was the first time that the character of Miss Marple had been depicted outside the original books and she was portrayed by Barbara Mullen. It was first performed at the New Theatre, Northampton on 17 October 1949 prior to moving to the Playhouse Theatre in the West End where it opened on 16 December 1949. This play, staged in 1949–1950, was the first time that the character Miss Marple was portrayed outside the novels and short stories.

Whatever the truth of the authorship, Christie was enthusiastic about the play and attended its rehearsals and first night. Christie's official biography suggests that the play was written by Christie with changes then made by Charles and Toy, presumably enough for them to claim the credit.
