NKVD against Gestapo. Soviet intelligence operations

The activities of the Foreign Department (Foreign Intelligence) of the NKVD on the eve of and during the Great Patriotic War in Germany and in Western Europe are traditionally hidden behind the curtain of GOSTaina. And the point is not only the secrecy of everything related to the activities of domestic intelligence. But with a refutation of many official myths. For example, as a result of political repressions of 37 years, Soviet intelligence was completely "blinded". The agent network in Western Europe was defeated solely thanks to the professionalism of the special services of the Third Reich, and not because of the series of gross errors made by Moscow.
The author not only refutes these and other myths, but also talks in detail about the work of the Foreign Department of the NKVD
