Don't be misled by the books and the movies having the same titles. With few exceptions, the stories in the books are entirely different. In some cases, there's some sort of common theme, but it doesn't matter. In only one or two cases, the movie is close enough to give some of the story away.

Fleming was a bit of a jerk, IMHO - he was really into brand names, status symbols, and such. (Look at his author's picture - gun, cigarette, pose - blech.) But the idea of a postwar spy guy who doesn't really care much about living, and who therefore gets life's relish by living on the edge all the time - this works well. Some of the books are really well done.
