Military journalist and writer M. Boltunov still remains faithful to his favorite topic - the topic of intelligence. The first part of the author's new book is devoted to the history of the development of Russian legal residencies abroad - military attachés - from the day of their foundation until the end of the Great Patriotic War. The second part is a fascinating story about the activities of military attaches in the post-war period and until today. The book is of undoubted interest for a wide range of readers.
