18: The No. 1 Ladies' Detective Agency: Alexander McCall Smith: ISBN 0-349-11675-X
Well, my mum and the anonymous commenter on a recent post were both right to recommend this. I found it a little slow to start but utterly utterly charming. Lovely characters, a nice meandering sort of plot, with lots of little mysteries solved and one bigger one running through the rest of the book. And some looking back at the past, childhood and young adulthood and the life of her father. Two generations of Africans living in Botswana, and loving their country. It's a beautiful portrait of a country, as well as of the people living there and their friends. I shall look forward to reading the sequels at some point.
