DEAD-END ROAD is the third book from Richard Kunzmann, but the first I've read. This was a scheduled read on the Murder & Mayhem list, which is why I'm out of order again with a series.
So far - very confronting.
From the Blurb:
After two years' absence, Detective Harry Mason has rejoined the South African Police Service, but is now moved to the Serious and Violent Crimes unit.
