It was later adapted for television as part of BBC1's Play for Today series which was transmitted on 28 October 1971.
The play is largely a two-hander comprising a series of vignettes featuring pillow talk between the characters referred to in the script simply as 'The Man' and 'The Girl'.
He is a city professional in his mid-thirties, she is a middle class housewife in her early twenties; both are enjoying an extra-marital affair, meeting every Tuesday afternoon to make love while The Girl's husband works late at the office.
In an attempt to keep their love for each other alive, he invents a mistress called Evelyn who he intends to leave, along with his wife, so that he can be with The Girl – believing that this will finally persuade her to abandon her other lovers for him.
The play ends with a telephone conversation between the two, The Man suggesting times and places for them to meet, only for The Girl to inform him that she is unavailable.
