Quietly competent young Joanna moves with her scatterbrain mother to a country village to take up her first job as District Nurse. She soon overcomes the suspicion of her patients used to someone rather older, while becoming romantically involved with a local farmer - at least until he tries to evict a newly-arrived expectant couple who park their caravan on his land.
When her father dies, Epifania Parerga, an Italian in London, becomes the world's richest woman. She feels incomplete without a husband and falls in love with a humble, Indian physician, Ahmed el Kabir, much loved by his indigent English patients.
