The book is dedicated to one of the most difficult and dangerous professions - intelligence. The author is a professional intelligence officer and professional writer; this gives him the opportunity to deeply and knowledgeably delve into the subtlest complexities and secrets of the ancient profession. The writer is far from Superman adventures, because the real intelligence missions that he himself carried out during the war and during his years of service in the Main Intelligence Directorate after the war will be much more interesting for readers.
