Summary: Even though this book is the fourth in the series about the No. 1 Ladies' Detection Agency, it could easily be picked up and read, not having read the previous three books. The reason is that the author starts the book by giving a good summary, in several pages, of the most important points of the previous books. As good as each book in the series has been, it seems as if every new book is even better!
This book imparts the wisdom of experience through the characters. I actually cried with the characters when they cried. This book finds Precious Ramotswe still unmarried, and Mma Makutsi starting a typing school, and with a boyfriend. The cases taken on are as interesting as always, and their resolutions impart wisdom to the reader. This book left me immediately eager to pick up the fifth book in the series.
