Sheridan's second husband, film executive
John Davis, whom she married in 1954, insisted that she give up acting and stay at home with her children. After their 1965 divorce (which was granted to Sheridan on the grounds of cruelty, as reported in contemporaneous press coverage, and cited in obituaries including in
The Times), she resumed her career appearing in Margaret Williams' comedy ''Let's All Go Down the Strand'' in 1967, alongside
Gladys Cooper and
Evelyn Laye, at the
Phoenix Theatre. ''Let's All Go Down the Strand'' began a prolonged period of success in London's West End, with Sheridan appearing in both comedic and dramatic roles for the next 25 years. She starred in Ronald Gow's
A Boston Story (1968, opposite Tony Britton, Duchess Theatre); Ira Wallach's
Out of the Question (1969, again opposite Dame Gladys Cooper, St Martin's Theatre), and in the title role of Ray Cooney's
Move Over Mrs Markham (1972, again opposite Tony Britton, Vaudeville Theatre). She played the Countess of Chell in Waterhouse & Hall's
The Card (1973, with Jim Dale, Queen's Theatre), and starred in Frances Durbridge's

Donald Sinden and Gwen Watford, Vaudeville Theatre). The latter production was recorded and transmitted on BBC Television. During 1978/79, Sheridan starred opposite John Gielgud in
