Mma Precious Ramotswe solves cases for wives whose husbands have gone missing, for a school teacher whose son has disappeared by finding the kidnappers, for a wealthy father whose 16-year-old daughter is frustrating him by going out on her own. She helps a man atone for the sins of his youth by finding the people he hurt decades earlier. She uncovers a scheme by twin brothers to use one medical degree and certificate between the two of them. She solves a case for herself when she thinks she must seek a divorce from her first husband but learns differently when she seeks out his mother. Her personal life has a main sorrow, that her only child lived just a few days, as the child's father beat her during the pregnancy, a story told in retrospect. This led her to decide never to marry again after he left her. Her joy is her engagement and eventual marriage to Mr J. L. B. Matekoni, who has taken on foster care of a sister and brother from the orphan farm. The cases are set in the cities of Botswana, mainly on the edge of the Kalahari desert, rather than in the desert. There are occasional forays into neighbouring nations.
