The writer, a man of great courage, Georgy Mikhailovich Bryansky, dedicated his story to his fellow security officers.

The book is written in the form of the diary of Andrei Trapeznikov and notes of Dmitry Bragin - two friends who worked side by side in the state security agencies for more than a decade .

The first part covers events from December 1933 to February 1940. It shows the struggle of our security officers against the German stations on the eve of the attack of Nazi Germany on the USSR.

The second part describes the most dangerous work of our intelligence officers in the territory temporarily occupied by the Nazis, the brave struggle of Soviet patriots against the fascists.
