"The Limpopo Academy Of Private Detection" by Alexander McCall Smith (Preowned Paperback)

No. 1 Ladies' Detective Agency #13

Precious Ramotswe is very busy these days. The best apprentice at Tlokweng Road Speedy Motors is in trouble with the law and stuck with the worst lawyer in Gaborone. Grace Makutsi and Phuti Radiphuti are building the house of their dreams, but their builder is not completely on the up and up. Most shockingly, Mma Potokwane, the orphan farm’s respected matron, has been dismissed from her post. Mma Ramotswe is not about to rest when her friends are mistreated. Help arrives from an unexpected visitor. He is none other than the estimable Mr. Clovis Andersen, author of The Principles of Private Detection, the No. 1 Ladies’ prized manual. Together, Mma Ramotswe, Mma Makutsi, and their colleague help right injustices that occur even in their beloved Botswana, and in the process discover something new about being a good detective.
