see diamonds being sorted and polished. In 1955 Brownrigg also introduced Fleming to Sir Percy Sillitoe, former head of MI5, who was working for De Beers and investigating the illicit diamond trade through the International Diamond Security Organisation. Fleming met Sillitoe and used much of the research as background material for his fictional Bond novel, Diamonds Are Forever. Fleming retained an interest in the subject and when Sillitoe suggested to the editor of The Sunday Times, Denis Hamilton, that the paper may want to write a story on the International Diamond Security Organization, Hamilton offered the story to Fleming. Sillitoe also offered his deputy, retired MI5 officer John Collard, as liaison for Fleming to interview. During World War II, Collard had assisted in the planning of Operation Overlord as part of MI11 and had joined MI5 under Sillitoe at the war's end. Whilst in MI5 he played a major role in the capture and conviction of the atomic spy Klaus Fuchs, before Sillitoe had approached him in 1954 to work for the International Diamond Security Organisation.

Michael Crampton, writing for The Sunday Times considered it an "exciting and richly fascinating account" and thought Fleming authored a book that "ringing true as fact, is at the same time as highly entertaining as any fiction." The Times Literary Supplement obtained the services of the Earl of Cardigan to review the book. He noted that "the book is put
