My favorite books in this series are filled with authentic stories of Africa and her people. As the series has developed, it's often reading more like people anywhere rather than Africans.
The Miracle at Speedy Motors examines the themes of marital love, parental responsibility, honesty, jealousy, commitment, bonding, handling mistakes, and friendship. In keeping with the detective focus of the series, there are cases to be solved. A woman wants to find an unidentified person. Mma Ramotswe and Mma Makutsi receive threatening letters. A landlord wants to get rid of a tenant.
The focus of the book, however, is on the relationships among the continuing characters, especially Mr. J.L.B. Matekoni and Mma Ramotswe, Mr. Phuti Radiphuti and Mma Makutsi, Mma Ramotswe and Mr. Polopetsi, and Mma Makutsi and Charlie in the garage. You also get to read more about Mma Potokwane and Motholeli than in most of the other books.
What made the book special to me were the heart-felt commitments that some of the characters made towards doing the right thing, no matter what. Alexander McCall Smith loves people and when he expresses that love through his characters it feels great just to be alive.
I found Mma Makutsi more annoying than usual in this book, and not nearly as funny in her foolish scenes. Otherwise, I would have graded the book at five stars. I hope that the next book will focus more on Precious and her family.
