What does it take to deceive those closest to you? How do you lead a double life and not lose yourself? Is there ever a point of return? These are the themes – and more – that Jonathan Ancer explores as he tells the tales of some of South Africa's most unusual and successful spies: from the navy superspy on the Russian payroll to the party girl who fell in love with Cuba, from the accidental mole in the heart of Pretoria's war on the frontline states to the idealistic students used and abused in apartheid's intelligence war. Their journeys into the shadow world of espionage raise questions about conscience, trust, forgiveness and the very notion of truth in a country that was at war with itself. From the author of 'Spy: Uncovering Craig Williamson', this new book gets under the skin of what it takes to betray those closest to you – and what it is means to be betrayed.
