It has never occurred to Precious Ramotswe that there might be disadvantages to being the best-known lady detective in Botswana. But when she receives a threatening anonymous letter, she is compelled to reconsider her unconquerable belief in a kind world and good neighbours. While she ponders the identity of the letter-writer Mma Ramotswe has a further set of problems to solve, both professional and personal. There is an adopted child's poignant search for her true family, and Mr J. L. B. Matekoni's pursuit of an expensive miracle for their own foster daughter Motholeli. With these latest developments on Tlokweng Road, Alexander McCall Smith reveals with all his brilliant storytelling skill that there are very few troubles that cannot be solved with kindness, and very few dry seasons that do not end with welcome rain.
