Mr. J.L.B. Matekoni attends a course hosted by the local chamber of commerce entitled “Where Is Your Business Going?”. But rather than feeling energized, he comes back in low spirits, unsure how to grow the already venerable and successful Tlokweng Road Speedy Motors. Then an old friend from school approaches him about a new business venture that could be just the ticket. When it turns out he will need to mortgage his property in order to pursue this endeavor, Mma Ramotswe and Mma Makutsi wonder what this will mean for his current business - as well as their own.

Mma "Precious" Ramotswe sets up a detective agency in Botswana on the edge of the Kalahari Desert, making her the only female detective in the country. At first, cases are hard to come by. But eventually, troubled people come to Precious with a variety of concerns. Potentially philandering husbands, seemingly schizophrenic doctors, and a missing boy who may have been killed by witch doctors all compel Precious to roam about in her tiny van, searching for clues.

In this dual collection of short stories, Alexander McCall Smith brings his trademark humor and warmth to inventive tales of spying and vengeance. In one story, a spy dropped deep into enemy territory manages to disguise himself—quite convincingly—as a nun. In another, an invitation to join the Vatican Secret Service sends a prospective operative down a rabbit hole of controversy and confusion. A third story finds an author, on the brink of public ruin, seeing the error of his ways after an act of kindness saves the day.

The complete BBC Radio adaptations of The No.1 Ladies' Detective Agency featuring Botswana's only female private detective agency, run by the irrepressible Precious Ramotswe. Based on the hugely popular novels and brought to life with music and full casts, these evocative productions return us to Botswana, where Precious has more mysteries to solve.

The brilliant Alexander McCall Smith became an international sensation with his New York Times best-selling No. 1 Ladies' Detective Agency novels. His award-winning wit, made famous through that series, is fully on display in 44 Scotland Street.
