Before you is another case of a “dashing couple” from the Institute of Experimental History - the desperate Valdar Kamdil and his bosom friend nicknamed the Fox. The case of the disappearance without a trace of their “brother in the profession” - Jacob Gernel, introduced into the circle of Ivan the Terrible under the legend of an astrologer - the soothsayer. Who kidnapped Jacob? Perhaps the suspicious to the point of paranoia, the “king’s dog” Malyuta? Or, on the contrary, emissaries of the Swedish king Eric? Or maybe the poor fellow became a victim of the “internal squabbles” of the adherents of the Royal art? Valdar and Lis are sent to “golden-domed Third Rome” - and immediately become entangled in the labyrinths of oprichnina intrigues, Cossack machinations and far-reaching ambitions of the Polish-Lithuanian Commonwealth. And this is so, banal everyday life. But what will be the EXTREME SITUATIONS?!
