Francesca and Camilla are identical twins. Camilla is the brighter variation on the theme and Francesca has her nose stuck in a book. After a holiday romance, Francesca marries Will, a middle aged African builder. At their wedding, Aunt Grace wears black and announces: 'Francesca's life is going to change utterly when she's forty. Mark my words Francesca...'; Everyone laughed at the time, even Francesca. 'She shouldn't be allowed anything stronger than cooking sherry', they said. Now Francesca is forty. She has three small children under the age of three and she's pregnant again. Aunt Grace's eccentric prediction has come back to haunt her because there is a whisper on the dusty streets of Botswana - Wendy Smith, the large breasted dentist has taken a lover. He is a married man with children and he hates his family and cannot bear to live with them a minute longer. Can it only be coincidence that Will is in Jo'burg on business and cannot be contacted at the same timer as Wendy is in Jo'burg at a dental conference?
