I have actually found most SA folk haven't heard of Tom Sharpe books. And they have all loved them.
He has a set of characters in three books based on the South african police force
Konstabel Els, Lieutenant Verkramp and Kommandant Van Heerden.
Being a well balanced chap he also wrote a series of books taking the piss out of the English lifestyle with Wilt and Poterhouse Blue etc.
Well worth getting them on a kindle if you like a good chuckle down route.
