African diamonds are being smuggled into the United States via London and it's up to the British Secret Service to infiltrate the organized crime families in America and destroy the smugglers. James Bond is not afraid of gangsters, but then he hasn't really met any—until now. With advice from his American friend, Felix Lieter, Bond tracks the diamonds from the deserts of Africa, to the diamond markets in New York and the gambling palaces of Las Vegas; penetrating into the very heart of the Mob. His trusted Baretta and the beautiful, hard-boiled Tiffany Case, are close by his side as he unwraps the secret eschalons protecting the head of the Mob...the man who has ordered Bond's death.
