Query: Not worth the time

This is just not a good book. The characters are one-dimensional and completely unrealistic, the story is a hodge-podge of cliches bunched together in a completely implausible fashion. Moss is an expert on 80's Russia, but some of his misses here are just laughable and he doesn't have enough writing chops to make the story compelling. Don't waste your time on this, read a LeCarre book instead, or a Forsythe if you like espionage action, both of them are several leagues above Moss.
