The rains are coming, but not just yet. When they do, there will be green shoots of growth throughout Botswana. Pumpkins will flourish - particularly those of Mma Potokwani, matron of a children's home and old friend of Precious Ramotswe. Mma Potokwani and Mma Ramotswe have many other things to talk about, including a new friendship that Mr J.L.B. Matekoni has struck up with Mr Freddie Mohlala, a prominent figure in the motor trade. Freddie Mohlala has invited Mr J.L.B. Matekoni to go fishing with him on the local dam - which is home to some fairly nasty crocodiles. They do not catch anything, but something nearly catches them.In the meantime, Mma Ramotswe looks into what seems to be a straightforward matter involving a husband who thinks his wife may be having affair. But there is a surprise in store: she, it transpires, suspects that he himself has a lover. This is obviously a case that will require tact - which of course is a quality Mma Ramotswe has in abundance. Along with kindness.For Botswana is a kind country, and in this latest visit to the No. 1 Ladies' Detective Agency we are reassured that no matter how unhappy the world may be, there is always an oasis of courtesy and peace in that special place in southern Africa. To which you are now invited.
