A recent event has prompted me to re-read the Kramer & Zondi novels of James McClure.They are set in apartheid South Africa.Tough and uncompromising they illustrate they practical relationship between a white and a black policeman of the time.They are also excellent examples of crime fiction of the police procedural variety.Featuring every shade of human venality, frailty and weakness, for me they provide perfect vehicle to illustrate the wasteful insanity of apartheid:The way the much more intelligent Zondi manages the honourable but not too bright Kramer is a delight.It would be interesting to learn the opinion of someone with more direct experience of South Africa than my own.
