It's summer 1735. “Bironovschina” is a terrible time for the country. People disappear at night, the rack and the red-hot tongs of the executioner in the Secret Chancellery know no rest. A troubled period on the eve of the Russian-Turkish war, when a dexterous and enterprising man with a sword and a pistol can radically change his fate - and the fate of the country. Courland Baron Dietrich von Hofen, who decided to try his luck in “barbaric and wild Muscovy,” is ready to risk his neck and undergo any tests in order to prevent the palace coup of “Peter’s daughter,” the dissolute Elizabeth. Here and now, on the muddy banks of the young imperial capital, in the light of smoldering lamps, in the ballrooms of palaces and in stuffy taverns, a new future for Russia, a new future for the whole world is being forged. If you are a real guardsman and don’t know how to retreat, take fate by the throat and turn the flywheel of history!
