As Botswana awaits the familiar blessing of the rains and the resumption of the eternal cycle, seismic upheaval is taking place at the No. 1 Ladies’ Detective Agency. Not only is Mr J. L. B. Matekoni attempting to reform himself into a modern husband, but after her marriage to Phuti Radiphuti, Mma Ramotswe’s challenging but irreplaceable associate Mma Makutsi has joyful news.

With the arrival of an heir to the Double Comfort furniture empire and Mma Makutsi busy with motherhood, Mma Ramotswe must tackle tea-making and detective work alone. Well-known troublemaker Violet Sephotho may or not be behind a smear campaign against the Minor Adjustment Beauty Salon, and a dispute over the will of a local dignitary points to a shocking family secret. But the No. 1 Ladies’ Detective Agency is resilient and adaptable, and change brings salutary lessons: that our enemies are not always obvious, that a snake under the bed may be an ally, and that a mother’s love conquers all.
