In September 1925 du Maurier and Gladys Cooper took a sub-lease of the theatre to present "The Last of Mrs Cheyney" by Frederick Lonsdale (1925), which ran for 514 performances, until the end of 1926. "Interference" (1927), a thriller by Roland Pertwee and Harold Dearden, was another big success and ran for 412 performances. It was followed by a flop, "S.O.S" (1928), notable only for starring Gracie Fields in her first straight part. In 1929, Alfred Lunt made his London debut, starring with his wife Lynn Fontanne in "Caprice", presented by C. B. Cochran, a comedy about a man, his two mistresses, and his son by one of them who falls in love with the other.
