Precious Ramotswe has always idolised her father, the late Obed Ramotswe.
She feels that she knows all about his life but does she? Sometimes our parents surprise us, and we discover that things were not quite what we thought them to be.
And the same goes for Mma Makutsi, Mma Ramotswe's feisty assistant, who also makes certain discoveries about her own past that cause some surprise.
The placid world of the No 1 Ladies' Detective Agency is further disturbed by the arrival in Gaborone of somebody whom Mma Ramotswe and Mr J.L.B. Matekoni, for that matter definitely do not want to see.
Of course calm eventually prevails as it always does in the timeless world of these remarkable ladies. Tea is served, and life continues.
