"When the Muscovites learn that she is a Catholic--and the truth cannot remain much longer hidden--it is doubtful whether their loyalty will be able to stand the shock. They may rise in arms and endeavor to seat the Duke of Bora on the throne, who has three recommendations in their eyes; he is of the Greek Church, a Muscovite on the mother's side, and connected, as I have said, with the blood-imperial of Russia. "Hence, in the opinion of the cabinet, the necessity for the marriage of the princess with the duke; their joint occupation of the throne is the only thing that can keep Pole and Muscovite from cutting each other's throats. A son born of this marriage will tend to unite the interests of both parties." Barbara with a son! And by the duke! The thought set Paul's blood on fire. "The cabinet of course are united on the question of this marriage?" he asked. "They mayn't like it, but, as I have said, they feel its necessity. I can name two ministers, however, who, outwardly assenting, are secretly opposing the match." "And they are--?" "Cardinal Ravenna and Marshal Zabern." Ravenna! It was rather surprising to find Barbara including among her ministry the ecclesiastic who had formerly inspired her with aversion. Then Paul's surprise ceased when he reflected that the cardinal was master of her secret history, and would therefore require to be conciliated. An uneasy suspicion began to form in his mind that Barbara was the innocent victim of a Jesuitical conspiracy--that she had been duped into believing herself a princess by ecclesiastics who intended to make use of her as a tool. "A Latin cardinal," he said. "I can understand that he would oppose the marrying of the princess to a Greek heretic. But Zabern--who is he?" Trevisa smiled. "You will not be long in Czernova without learning who Zabern is. He is the Warden of the Charter, the most subtle character in the cabinet, the idol of the Czernovese Poles, whose motto is 'Trust in God and Zabern--especially Zabern.' Ask the Muscovites who Zabern is, and they will blaspheme and tell you that he is the incarnation of the devil. And as the slaying of the devil would be a holy act, their pious attentions in this respect have compelled the marshal to go about with chain-mail beneath his clothing." "And Zabern, you say, is opposed to the match? But if the princess has set her mind upon it, how does Zabern propose to play his game?" "His first card is the Pope." "The Pope?" "Yes. The princess, being a Catholic, is debarred by the canons of her Church from marrying the duke, inasmuch as he is her first cousin. The papal dispensation is necessary before the union can be celebrated." "And should the Holy Father refuse to grant it?" Trevisa's face assumed a very grave expression.
