"Phantom" is an action-packed political detective story. It is an artistic synthesis of a number of cases carried out in recent years by the Russian FSB against state traitors from among former high-ranking officers of the Russian army. The book tells in a fascinating way about the work of modern domestic counterintelligence. The plot of the book is based on the struggle of the FSB with the CIA to ensure the safety of the most important Russian secrets in the field of the latest nuclear missile developments. Honorary State Security Officer Major General V. Tarasov noted the following: “ N. Luzan’s book is based on the operation of our contemporaries from the military counterintelligence department of the FSB of Russia. Thanks to their dedicated work, it was possible to prevent the leakage of the most important state secrets in the field of rocket science. From the first to the last pages, the reader will be kept in suspense by the struggle between the two most powerful intelligence services - the FSB and the CIA. The book was written by a professional whose development as an employee and head of one of the military counterintelligence units took place before my eyes.” The book is intended for a wide range of readers.
