You can argue endlessly about Stalin. Some consider him a tyrant, others a wise ruler. But all opponents will agree with the statement that he accepted the country in complete ruin, and left it a powerful nuclear power. How did he do it? One of Stalin's successful projects was the organization of the "invincible and legendary" SMERSH, whose activities ultimately decided the outcome of the war. The book, based on the author's personal experience in intelligence agencies, will be of interest to a wide range of readers.
