Tears of the Giraffe by Alexander McCall Smith
On the one hand, this is quite enjoyable, nicely written and calming. On the other hand, it's too simplistic and positive. Tears of the Giraffe is the second in the No. 1 Ladies Detective Agency series, which takes place in Botswana. It reminded me of the one book in the Mitford series by Jan Karon that I've read.
