Welcome to the dark realm of betrayals, double cross and intrigue. Nobody is who they seem to be. Epigraphs to each part are simplest chess rules - at the first chapter, for instance, it states that in chess players go one after another. Closer to the middle of the book one feels the urge to go back and check with previous rules, 'cos suddenly they are important! The period and topic is thoroughly researched - even from my post-"Empire of Evil" background. Pity there are only 5 stars - I would give more to this book! If you do not like spy novels - try this one. I know - I hooked my girlfriend via this novel (she used to consider spy novels as an inferior sub-literature before :)
