Rain on the Just at the Aldwych Theatre. The play and its stars won good notices, but the piece had only a short run. Their next West End production together, the farce Queen Elizabeth Slept Here, pleased the critics less but the public more and it ran for 349 performances. 1950s After a seven-week pre-London tour, beginning in August 1950, Gray and Denison opened at the Ambassadors Theatre as Michael and Agnes in The Fourposter, a two-hander, charting the married life of a couple. A Broadway transfer was proposed, but the stars' commitments in Britain prevented it, and their roles were filled in the New York production by American performers. For the cinema Gray and Denison starred in The Franchise Affair (1951), and in December 1951 they headed the cast in a BBC television adaptation of Arnold Bennett and Edward Knoblock's play Milestones. Their penultimate film together in the 1950s was Angels One Five (1952). At the St James's Theatre in December 1952 Gray and Denison co-starred as Robina and Clive Jevons in Sweet Peril. On film they appeared in There Was a Young Lady (1952). In Alice Through the Looking Glass at the Prince's Theatre in February 1954 Gray played the White Queen and Denison appeared as the White Knight, Tweedledee and Humpty Dumpty. They reprised these roles the following year. At the Westminster Theatre in June 1954 Gray played Toni and Denison played Francis Oberon, her would-be murderer, in the comedy We Must Kill Toni. The couple toured South Africa from December 1954 to February 1955, in The Fourposter and Coward's Private Lives. In November 1955 Love Affair, Gray's first and last attempt as a dramatist, opened under Denison's direction at the Alexandra Theatre, Birmingham and transferred to the Lyric Theatre, Hammersmith in June 1956, with author and director in leading roles. It was not a great success. Its author fared better as a novelist than as a playwright: her first novel, a crime mystery, Murder on the Stairs, was published in the same year. It received good notices and sold well. She followed it with Murder in Melbourne (1958) and Baby Face (1959). In 1956–57 Gray toured South Africa and Australia as Lady Shotter in Coward's South Sea Bubble and Laura Reynolds in Robert Anderson's Tea and Sympathy − the latter regarded as daring in its day. In 1958 Gray and Denison toured Britain in a two-hander
