Both Book and Movie were bad

I watched the movie first and then read the book since so many people said the book was better than the movie. But after finishing the book I was on the fence. While John B was taken out of the movie, I didn't really see a need for him in the book--he was just a catalyst for Linda to get to Washington and then to spy. In fact, I found the entire relationship just icky and weird, since Linda opened the book revealing that she was in love with him, but their relationship was really just about sex. After snagging John in the sack, there was no talk or action of "love" from Linda, just lust, and the author never explained anything. For all the nagging that the movie was inept and impossible, what with Linda being able to waltz into Nazi Germany and Edward running around Europe not speaking a lick of another language outside of English, the book was exactly the same. Combine this with both movie and book versions of the traitorous Margrete of whom I never understood why the CIA/OSS so complicitly trusted someone so high up in the Nazi Regime (???!!!), and both book and movie were a pile of hot steaming mess. I was left waiting for the so-called Cinderella/Ugly Duckling plot all the sparkling amazon.com reviews praised, but all I saw were cardboard-flat characterizations and ickiest ending in the world (wtf? how was Linda not only in love with her husband's ex-father-in-law, but in love with a man who knew her husband was cheating with his ex-wife, Edward's daughter?) UGH. The image of the plot is nice: shy secretary in love with her boss who turns out to be a master spy, but the actual execution left much to be desired.
