Take a slow, deep breath, curl up in your favorite chair with a hot drink and prepare to enjoy another satisfying meal of literary comfort food. The latest instalment in the No. 1 Ladies' Detective Agency series may not win any new converts, but it will most definitely not disappoint its fans. All the familiar characters are back and their stories are woven in with little musings on subjects like always doing your best or the value of taking time out just to sit, gaze upon static things and be calm.

Ever since Mma Ramotswe embarked on her career as a private detective, her "bible" has been Clovis Anderson's book about the principals of private detection. She is thrilled to discover that he is visiting Botswana. They become friends, but it is apparent that Clovis is troubled by something. It's quite endearing to read her gushing praise of him, her assumption that he is internationally renowned, while he is clearly nothing of the sort. However they do work together on a case, which makes a refreshing change in formula.

Mma Ramotswe's a case is very dear to her heart. Her friend Mma Potokwani, wants her to check the motivations of a member of the orphan farm board. As the conflict between Mma Potokwani and her foe escalates, Clovis and Mma Ramotswe will need to combine their talents to get to the bottom of the affair.

Meanwhile, Fanwell (one of the Speedy Motors apprentices) is getting himself into hot water. A favour for an old acquaintance has lead into illegal territory. And Mma Makutsi's new husband has decided to build them a new home. However the builder whom he has chosen is not particularly interested in Phuti's input and is even less interested in anything that Mma Makutsi has to say. It also appears that one of his builders is wary of Phuti - but why?

If you love this series - as I do - you are bound to enjoy this addition to it.
