Those are generally very good. Of the movies, most people dislike "On Her Majesty's Secret Service" but of the books I find it to be one of the best. The spy game was finding a crack in the enemy's armor, a backdoor way into his world so that you could destroy him from within. Not a lot of gadgets really, but a deep understanding of the enemy so as to find his weakest spot and attack there. With Blofeld, it was his pride and vanity.
