Fleming captures the fading British Empire and travel by air and trans-Europe railways in the late 50's plus the tension with the USSR. I've read 7 Fleming novels so far and enjoyed this the most. Bond comes over as a more brutal spy than in the films, but he is also a patriot with a heart. The style briskly moves you through the plot and the villians are fabulously evil.
This is obviously a collection of thoughts and adventures by many brave people who fought their own type of underground war. I found it incredible that these mostly young men and women trianed and then launched themselves out an areoplane to fight the Axis forces. Very good read and very humbling!
