Nevertheless, in the weeks that followed, he brooded more and more over all that Basmanov had said. It was in the thought that the nobility of Poland was flocking to the house of Wisniowiecki to do honour to this false son of Ivan the Terrible, that Boris found the chief cause of uneasiness. There was famine in Moscow, and empty bellies do not make for loyalty. Then, too, the Muscovite nobles did not love him. He had ruled too sternly, and had curbed their power. There were men like Basil Shuiski who knew too much—greedy, ambitious men, who might turn their knowledge to evil account. The moment might be propitious to the pretender, however false his claim. Therefore Boris dispatched a messenger to Wisniowiecki with the offer of a heavy bribe if he would yield up the person of this false Demetrius. But that messenger returned empty-handed. He had reached Bragin too late. The pretender had already left the place, and was safely lodged in the castle of George Mniszek, the Palatine of Sandomir, to whose daughter Maryna he was betrothed. If these were ill tidings for Boris, there were worse to follow soon. Within a few months he learned from Sandomir that Demetrius had removed to Cracow, and that there he had been publicly acknowledged by Sigismund III. of Poland as the son of Ivan Vassielivitch, the rightful heir to the crown of Russia. He heard, too, the story upon which this belief was founded. Demetrius had declared that one of the agents employed by Boris Godunov to procure his murder at Uglich had bribed his physician Simon to perform the deed. Simon had pretended to agree as the only means of saving him. He had dressed the son of a serf, who slightly resembled Demetrius, in garments similar to those worn by the young prince, and thereafter cut the lad’s throat, leaving those who had found the body to presume it to be the prince’s. Meanwhile, Demetrius himself had been concealed by the physician, and very shortly thereafter carried away from Uglich, to be placed in safety in a monastery, where he had been educated. Such, in brief, was the story with which Demetrius convinced the court of Poland, and not a few who had known the boy at Uglich came forward now to identify with him the grown man, who carried in his face so strong a resemblance to Ivan the Terrible. That story which Boris now heard was soon heard by all Russia, and Boris realized that something must be done to refute it. But something more than assurances—his own assurances—were necessary if the Muscovites were to believe him. And so at last Boris bethought him of the Tsarina Maria, the mother of the murdered boy. He had her fetched to Moscow from her convent, and told her of this pretender who was setting up a claim to the throne of Russia, supported by the King of Poland.
