Paul whispered a few words into the ear of the marshal, who received the communication with an expression of incredulity. "It is true," asseverated Paul. "And," he added, "here comes the confirmer of my words." A slight commotion here took place at the far end of the cathedral, and there entered a man of distinguished presence whom Zabern immediately recognized as the Russian Minister for Foreign Affairs. Then the marshal no longer doubted. His face became lighted with an expression of joy, succeeded the next moment by one of trouble. "The Convent of the Transfiguration!" he murmured. "There is our danger. We are lost if our secret documents fall into the Czar's hands. And how is it to be prevented with a Russian regiment in possession of the monastery?" The newcomer on entering had thrown a quick glance around, and catching sight of the emperor standing upon the edge of the choir, he at once made his way to the imperial presence.

His search in the archiepiscopal palace had resulted in the finding of certain papers, so extraordinary in their character that the police-official felt constrained to hasten at once to Zabern with the news of his discovery. The sight of the duel had kept him dumb and motionless, but as soon as it was over he had hurried to the side of Zabern. "Marshal," he whispered, "what name did the Czar give to our princess?" "Barbara Lilieska. That is her true name, Casimir." "Then these papers do not depose her?" said the chief of the police, exhibiting what he had found. "Depose her?" repeated Zabern, as he ran his delighted eye over the document. "By the soul of Sobieski, you could not have brought a more acceptable gift to her Highness. This will--"
