Blue Shoes And Happiness by Alexander McCall Smith
Now that she is finally and happily married to her long-term suitor Mr J.L.B. Matekoni, Mma Ramotswe of the No. 1 Ladies Detective Agency of Botswana might have expected life to grow more sedate. But the many problems that lead customers to Mma Ramotswe's door seem, if anything, to have multiplied, and no sooner has she settled her traditionally built person into the married state than she finds herself looking into several troublesome matters at once. There is, to begin with, a disturbing case of blackmail and theft from the Government catering college. Then, while on an errand for her husband to the Mokolodi Game Reserve Mma Ramotswe is seconded to investigate an unpleasant atmosphere that may be down to witchcraft, or something worse. There are sinister goings-on at a health clinic to be looked into, not to mention any number of small wrongs to be righted along the path to detective triumph. And all the time Mma Ramotswe has weighty questions of a philosophical nature to consider, such as whether it is right to find happiness in small things, such as a new pair of blue shoes, a slice of cake, or a red sunset over the Kalahari.
