The Diamond Smugglers

The Diamond Smugglers is a non-fiction work by Ian Fleming that was first published in 1957 in the United Kingdom and in 1958 in the United States. The book is based on two weeks of interviews Fleming undertook with John Collard, a member of the International Diamond Security Organisation (IDSO), which was headed by Sir Percy Sillitoe, the ex-chief of MI5 who worked for the diamond company De Beers.
The IDSO was formed by Sillitoe to combat the smuggling of diamonds from Africa, where, it was estimated, £10 million (£304,531,779 in 2024 pounds[1]) worth of gems were being smuggled every year out of South Africa alone. The book expands upon articles Fleming wrote for The Sunday Times in 1957.
Fleming was better known as the author of a series of books about his super-spy creation, James Bond; The Diamond Smugglers is one of two non-fiction books he wrote. It was broadly well-received, although some reviewers commented on the stories not being new.
