The book was prepared on the basis of unique materials on the recent history of Russian counterintelligence transferred to the author by the Public Relations Center of the FSB of Russia. For the first time, many operations carried out by intelligence services in the last decade have been made public. Dossiers on the knights of cloak and dagger, petrodollars and the Islamic factor, legal Mossad illegals, features of the activities of Far Eastern intelligence services, meetings in Lefortovo and much more - all this is in A. Elizarov’s book “Counterintelligence. FSB against the world's leading intelligence services."
