Graham Browne, who had accompanied her throughout her tour, and who regularly partnered her onstage in her subsequent West End appearances. By the 1920s, Tempest had outgrown her troublesome temperament and moved into playing charming and elegant middle-aged women. In 1924 she took a singing part again in Clifford Bax's Midsummer Madness at the Lyric Theatre, Hammersmith. She created the role of Judith Bliss in Noël Coward's Hay Fever (1925), in which she was followed in later revivals by leading actresses from Edith Evans to Judi Dench.
