Another round of “mysteries” with the No. 1 Ladies’ Detective Agency in Botswana. Of course these aren’t generally “mysteries” in the sense of whodunnits (although there is a whodunnit in this one) but really the mysteries of life, the tiny – or not so tiny – philosophical puzzles that present themselves as we wend through our daily lives. And Mma Ramotswe is an expert at solving, or at least deliberating, such mysteries. She gently dispenses advice and comfort through these pages, as often as not with a touch of humour thrown in.
