Diamonds Are Forever

The licence to kill for the Secret Service, the double-0 prefix, was a great honour. It had been earned hardly. It brought James Bond the only assignments he enjoyed—the dangerous ones.
Diamonds Are Forever is the fourth novel by the English author Ian Fleming to feature his fictional British Secret Service agent James Bond. Fleming wrote the story at his Goldeneye estate in Jamaica, inspired by a Sunday Times article on diamond smuggling.
The story centres on Bond's investigation of a diamond-smuggling ring originating in the mines of Sierra Leone and ends in Las Vegas. Along the way Bond meets and falls in love with one of the members of the smuggling gang, Tiffany Case. Much of Fleming's background research formed the basis for his non-fiction 1957 book The Diamond Smugglers. Diamonds Are Forever deals with international travel, marriage and the transitory nature of life
