About the book: 1989 / Viktor Egorov is an old security officer. In 1968, readers became acquainted with his first book, “The Conspiracy against Eureka.” It told about how state security agencies, with the help of a Soviet security officer who managed to infiltrate the service of German intelligence long before the war, managed to thwart a terrorist attack by the Nazis against participants in the Tehran Conference. The theme that formed the basis of the second story was prompted by the repeated attempts of the US Central Intelligence Agency to provoke discord in Soviet relations Union with states that have embarked on the path of independent development. The case described here dates back to the fifties. For a number of reasons, some circumstances have been changed.
