In the Time of Five Pumpkins

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.
