The book of memoirs of Walter Germanovich Krivitsky (Ginsberg Samuil Gershevich, 1899-1941) "I was an agent of Stalin" offered to the reader is a confession of an illegal Soviet intelligence resident in Western Europe on the eve of a big war. The memoirs are unusual in that their author, by his high official position in our intelligence agencies, had the opportunity to look not only behind the scenes of the Kremlin, but also into some caches of the OGPU-NKVD.
