A History of Espionage and Betrayal. In this compelling investigation, author Michael Smith explores the critical moment in a spy's life: that split-second decision to embrace a double life; to cheat and hide and hurt, to risk disgrace - even death - without any guarantee of being rewarded or even recognised. Each chapter centres on a diffferent spy, following the path they took that lead, finally, to the point of no return. Were they propelled by personal convcticons? Blackmailed and left without a choice? Too desperate for money to think about the consequences?
