Set in the Soviet Union in the 1950s, the novel focusses on an agent in the State Security department. He is loyal, dedicated and hard-working, an exemplary employee of a cruel and barbaric regime. But events take an unexpected turn... And I won't say any more because I'd hate to spoil it. The backdrop is evocative - gritty and harsh with a distinct lack of human compassion - and the fact that elements of the book are based on actual events is quite scary!
All in all a good thriller which I'd recommend to anyone who likes a well-written, plot-driven novel.
