The publication of the book is associated with the approaching centenary of the Great Russian Revolution. At the center of the story are the circumstances of the concealment on the territory of the Khanty-Mansiysk and Yamalo-Nenets Autonomous Okrug of the values of the Siberian White Movement, taken from Tobolsk along the Tobol, Irtysh and Ob rivers in September 1919. These valuables and relics have not been found to date. Their searches were undertaken by the state security agencies of the Soviet Union in the 20-30s. The documentary investigation is based on previously classified documents transferred in September 1991 by decree of President B.N. Yeltsin from the archives of the territorial state security bodies of Tyumen, Yekaterinburg and Syktyvkar for state storage.
