Fans of the The Ladies' No. 1 Detective Agency will revel in the tricky new challenges the traditionally built Mma Ramotswe faces with her unique combination of common sense and kindness. Those who are yet to discover McCall Smith's witty and delightful writing will find that Botswana provides an evocative background for all the great problems of the world: justice, respect, whistle-blowing, feminism, forgiveness, friendship - and, of course, how to deal with an angry ostrich. Oh, and does money buy you happiness? Yes, if you use it to buy Blue Shoes (but perhaps not if you are Mma Makutsi, assistant to, though less traditionally built than, Mma Ramotswe herself). Why can't all the world be like this?
