Query: I feel cold

The cold in the title is spot on, this story left my cold (purposefully, I'm sure). The characters were either too cynical or had motivations I was unable to sympathize with, like the girl, who was a member of the communist party but in truth just wanted to get a husband. The book was very clear on that, she was as ordinary as it gets. Communists just recited typical communist propaganda, with a touch of nazism once in a while, and were hardly fascinating as the opponents. The ending was unsurprising, because it was obvious that one of two alternatives was true, and it wasn't even possible to admire the cold cleverness of the story. I don't know how it would puzzle anyone, even though the reviews say otherwise. If it had been a true story, at least I would know how espionage was really like. As a work of fiction I couldn't find anything in it to love, the characters or the plot.
