Count Phoenix. Cagliostro. Engelhardt N.

Spring of 1779. The adventurer Kagliostro comes to Petersburg to play on the feelings of the gullible public, show spectacular tricks, pretended to be miracles, and earn on this. Prince Golitsyn, a man from the closest encirclement of Catherine II, is involved in the intrigues of the adventurer. Fake magic makes him a strong impression, as in many aristocrats - for example, the relatives of Prince Potemkin. There is a danger that even the heir to the throne - Pavel Petrovich, will fall under the influence of Cagliostro, so it is necessary to expose the adventurer until it became too late.
