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, not sure if he should be satisfied with the already venerable and successful Tlokweng Road Speedy Motors. Then an old friend from school approaches him with an exciting new business venture. When it turns out he will need to mortgage the garage in order to pursue this endeavor, Mma Ramotswe and Mma Makutsi worry about the potential repercussions for his current business--as well as for their own. But even as she puzzles over mysteries on the domestic front, Mma Ramotswe's professional duties must take precedence. When a concerned son learns that his aging father's nurse now stands to inherit the family home, he begins to doubt her intentions and takes his case to Botswana's premier detective agency. Fortunately, Mma Ramotswe and Mma Makutsi, committed agents of justice, agree to investigate. Tricky as these matters may be, Mma Ramotswe, armed with her usual supply of tact, humor and good will, knows that the most creative solutions are often found with the support of friends and family and a cup of red bush tea. With these reliable assets, she is certain to ensure that all involved find the happiness that they deserve.
