The book is a documentary story about the investigation into the circumstances of the death of the legendary intelligence officer Nikolai Kuznetsov. The author, who at the described time was N. Kuznetsov's ally in the partisan movement, very accurately conveys the atmosphere of that time and writes about the events that went down in the history of the Great Patriotic War. In the modern political situation, when attempts are regularly made to revise historical facts and belittle the significance of the victory over fascism, the book acquires particular relevance. For a wide range of readers.
