In 1957, as the Cold War raged, Ian Fleming took a respite from writing James Bond to craft a work of nonfiction every bit as tense as a Bond adventure. Aided by an ex-MI5 agent and International Diamond Security Organization operative going by the alias “John Blaize,” Fleming chronicled the IDSO’s infiltration of the “million-carat network”―the world’s most notorious diamond smuggling ring. Every year, a shadowy band of racketeers pirated a fortune in diamonds out of Africa, and the majority of the stolen gems wound up in the hands of Communist nations. In response, the IDSO commissioned a private army, led by legendary British spymaster Sir Percy Sillitoe, to penetrate and topple the ring. When the operation was complete, the Sunday Times gave the story to Fleming. A remarkable feat of investigative journalism, this is the thrilling true story behind one of the greatest spy operations in history.
