Blue Shoes and Happiness by Alexander McCall SMith

Blue Shoes and Happiness is the 7th book in the series of mysteries featuring Mma Romatswe, the proprietress of the No.1 Ladies Detective Agency in Botswana. Mma Romatswe has a number of mysteries to solve in this outing.

There is a blackmailer who has endangered the job of one of her clients (by blackmailing the clients supervisor, who blames her), there is a mysterious fear troubling the village of Mokolodi (which is near a game reserve), and there is a doctor behaving strangely about blood pressure medication. In addition to the mysteries, Mma Romatswe is concerned for her second in command, Mma Makutsi.

Mma Makutsi has recently become engaged to a man who owns a furniture store, Phuti Radiphuti. Unfortunately, she has told him she is a feminist, which she fears has frightened him. In order to reassure Phuti, she takes Mma Romatswe's husband, Mr. J.L.B. Matekoni shopping for a new chair at her fiance's furniture store. While they are looking at a chair, Mma Makutsi reassures Phuti that she is not the kind of feminist who thinks men are unimportant.

Many other adventures take place, in the somewhat by-the-way story of the novel. A cobra under Mma Makutsi's desk is dealt with, Mma Romatswe tries dieting, and Mma Romatswe thinks about her wonderful late father, for whom she was truly Precious.
