I really really enjoyed this book. Once again, I read it with my head full of the film, and once again the bare bones of the story is very similar.
But in movie terms, this is where they started to deviate from the books to deliver spectacle. The end of the book (the actual attack on Fort Knox) is very different, but apart from that most of the other differences are superficial.
But actually the book was far more interesting. We see Bond in a desperate situation, he actually feels like he is going to die in a way that he never has before (although this was largely an effort to humanise him, the main critics of the series said they didn't like it because the main character was a ruthless killer).
The end of the book would not have made a great film - the last three Bond books that I have read were actually the first three movies, in a different order, and it is always the end that they play with - quite rightly - to give the movie a decent set piece at the end. Here they have taken the most liberties, because in the book there is no Flying Circus and the baddies don't even reach Fort Knox. And Oddjob is a massive bloke in the book.
But the pacing and the threat are great in this book. The critics seemed to think that From Russia With Love is the best book in the series so far but in my opinion it is not, Goldfinger is by a fair margin.

21.10.23 I re-read a Folio Society edition of this book. Generally, I agree with my previous comments - it’s best book in the series so far. The only thing that left a slightly and hasn’t taste in the mouth was the last couple of pages. Having saved the day, Bond then seduces a lesbian (Pussy Galore). I’m sure she was grateful for what he did, but the seduction seemed somewhat… unlikely. Still, a great book.
