Amid the ashes of the Soviet Union a Russian army doctor turned spy addresses the woman he loves -- a fellow spy who has shared his shadowy life in Africa, Europe and the Middle East, but who has disappeared. The tale he unfolds spans three generations of his family, ordinary people caught up in the convulsions of the Russian empire in the twentieth century, from the civil war through the Second World War to beyond the fall of communism. It is a tale of brutality and soured dreams yet also one of altruism, tenacity and immense courage, written by a master.
