Mr. J.L.B. Matekoni attends a course hosted by the local chamber of commerce, but rather than feeling energized he comes back in low spirits, unsure how to grow the already venerable and successful Tlokweng Road Speedy Motors. An old friend from school approaches him about a new business venture, but it turns out he will need to mortgage his property in order to pursue this endeavor. In a new case for Mma Ramotswe, a concerned son learns that his aging father's nurse now stands to inherit the family home. As Mma Ramotswe and Mma Makutsi investigate, they must rely on their tact, humor, and goodwill to ensure that all involved find the happiness that they deserve.
