If you are the founder and Managing Director of the No. 1 Ladies' Detective Agency you may expect complete strangers to approach you with their problems when they see you having dinner with your husband in a peri-peri restaurant. And if you are Precious Ramotswe, you are a kind and helpful person who will be willing to take on a quest to find the relatives of a man who, many years ago, left the country for the uncertainties and dangers of a distant conflict. While that is going on, though, there may be other things that claim your attention - such as the shocking news that a club that calls itself the Cool Singles Evening Club is encouraging married men to pretend to be single and meet women under false pretences.

Who can be behind such a distasteful venture? Mma Ramotswe shows great tact in dealing with this situation, and avoids harm to the innocent. And all the time, she and her assistant, Grace Makutsi, are getting on with their normal lives - which, of course, include birthdays and the buying of birthday presents. A new dress makes a fine present, but not if, when being tried on, it splits in a way that is thought to be irreparable.

Mma Potokwani has dealt with situations far worse that, and in dealing with this local emergency she shows her characteristic wisdom. At the end of the day, disaster is averted. Life in Botswana, that far and lovely country of the title, continues smoothly, which is what Mma Ramotswe and her friends want - and most certainly deserve.
