In the most recent volume in the No. 1 Ladies Detective Agency series, a few surprising things happen. Without them there wouldn’t be much plot, so I won’t spoil it by saying what the surprising events are. Mma Ramotswe and Mma Matutsi carry on with their usual tenacity and goodness, and it all turns out well in the end. This is one of the better books in the series, although they all have their charms.
