It is a clever read with several twists and interesting characters. It also gives good insight into the Soviet mindset at the time from the perspective of the different characters. Throw in some spying stuff and it is all good. Like I said, I really enjoyed the book.
It is an older book, published in 1989 and there are already something like 100 copies on PBS so I am not expecting this book to move. No problem though, it will be a good one to post in case I run a deal sometime, it could be the type of book someone would want at that point.
