Precious Ramotswe is now married to Mr J. L. B. Matekoni of Tlokweng Road Speedy Motors. Her No.1 Ladies’ Detective Agency is frantically busy, but Mma Ramotswe cannot ignore the pleas of a woman in particularly dire straits.

Unfortunately, her attempts to help are interrupted by a spectacular disagreement between her assistant, Mma Makutsi, and one of the apprentices at the garage. How can this apprentice be rescued from the folly of a fancy girlfriend who drives a Mercedes-Benz?

Fortified by plenty of contemplative cups of bush tea, Mma Ramotswe sets out to find the answers.
