Often there are some differents between the novel and the book. In the case of "Goldfinger" it's the same. Only James Bond's new oppenent, a goliath of a cheater and evil enemy, is the one like in the film. He is about to do the "crime de la crime". The greatest gold robbery in the world and the killing of over 60.000 people is the deadly plan of the agent of SMERSH, Auric Goldfinger.
Bond ist the only one who can stop the fatal plan, but with the time he sees that Goldfinger is more than he thought. The great genius is one of Bond's greatest and deadliest enemies, but soon Goldfinger will recognize, that he's not the only great genius in the world.
