A. Maksimov’s new book is dedicated to the Hero of Russia, the legendary employee of the Foreign Intelligence Service L.R. Kvasnikov, who is called the ideologist and strategist of atomic intelligence. From his youth, Leonid Romanovich’s life path was connected with technology; He devoted a quarter of a century to intelligence, and its extremely specific direction - scientific and technical. Having arrived within the walls of the NTR, Kvasnikov began to lead a team of intelligence officers of four people on the eve of the war, dozens during the war years, in the Center and abroad, and many dozens during the Cold War. The author could not (and did not dare) keep silent about him also because he was his mentor in operational matters in the 60s of the 20th century. Anatoly Maksimov is a veteran of the navy, military counterintelligence, intelligence; Honorary State Security Officer, member of the Writers' Union of Russia; author of the books “Scout of the Atomic Age” (about V.B. Barkovsky), “Atomic Bomb of Anatoly Yatskov” and other works about the intelligence services.
