I'm a sucker for spy novels, so when someone left this at our bookswap brunch, I zero'd right in on it. I definitely enjoyed it, but didn't think it had much substance. However, it was a perfect novel to relax the mind.
I enjoyed the descriptions of East Berlin and West Berlin and the Anarchists and Communists. The descriptions of how the double agents were made was a lot of fun. Being a real spy would not be fun, if you really had to pretend to be in a dead-end job with no ambition. It was definitely interesting to be thrown back into a cold-war novel, though at the end I found it a little boring and I started skimming.
