It is a troublesome fact that there are things which men know and ladies do not, and vice versa.

It is unfortunate, for example, when Mma Ramotswe’s newest client is Luengo Malefololo, owner of the failing Kalahari Swoopers, that one of the things even lady detectives know very little about is football. And when Mma Makutsi’s old enemy, the glamorous Violet Sephotho, sets her sights on her unsuspecting fiancé Phuti Radiphuti, it becomes exasperatingly clear that men do not know how to recognise a ruthless Jezebel even when she is bouncing up and down on the best bed in the Double Comfort Furniture Shop.
