Bond is tasked with investigating a major diamond smuggling ring which begins in Africa and runs through Holland and the UK to the United States. Disguised as professional smuggler and murderer Peter Franks, Bond travels to Amsterdam to meet contact Tiffany Case: he is given the diamonds and travels on to the U.S., where he is met by Felix Leiter. Bond moves through the chain, which leads to the Whyte House, a casino-hotel owned by the reclusive billionaire Willard Whyte.
Bond follows the diamonds to a pick-up by Bert Saxby, Whyte's head of security, and then onto a research laboratory owned by Whyte, where he finds that a satellite is being built by a laser refraction specialist, Professor Dr. Metz. Suspecting Whyte, Bond tries to confront him, but instead meets Blofeld, who captures the agent and explains to him that the satellite can blow up nuclear missiles. Blofeld admits that he intends to auction it to the highest bidder. Bond escapes and frees the captive Whyte and they establish that Blofeld is using an offshore oil rig as his base. Bond attacks the rig, stopping Blofeld's operation and dispersing his organisation.
