Shadows of the Evening is a short play in two scenes, which together with A Song at Twilight and Come into the Garden, Maud forms a trilogy by Noël Coward known collectively as Suite in Three Keys, all set in the same luxury suite of a Swiss hotel. Shadows of the Evening is the most serious of the three in tone and theme. It depicts the relationship of a terminally ill man with his mistress and his estranged wife.
The play was premiered in London in 1966 starring Coward, Lilli Palmer and Irene Worth. It ran in a limited season for 60 performances. It received less praise from the press than the other two pieces in the trilogy, and was omitted when they had their Broadway premieres in 1974.
