On South Africa's Secret Service - An Undercover Agent's Story by Riaan Labuschagne

This is the story of the ruthless intelligence war conducted by South Africa’s
National Intelligence Service during the 1980s and 1990s.
The author, Riaan Labuschagne, was a senior intelligence officer who
operated widely as an undercover field officer.
He tells a story of lies and half truths, secrecy and stealth,
evasion and denials, deceits and manipulations. It had little to do with the
Calvinistic ethics of Christian nationalism that had provided the guidelines
for his upbringing as a young Afrikaner.
