"The Czar exceeds his authority in making such demand," replied Barbara with dignity. "By the decree of the Congress of Vienna, Austria and Prussia are equally concerned in this matter of the Charter. They have not yet called its existence in question. To a joint embassy from the three Powers doubt not that we shall pay due regard." Barbara's attitude in thus associating the courts of Vienna and Berlin with that of St. Petersburg upon the point at issue was diplomatically correct, as Orloff very well knew. Unless the two other states should act in concert with Russia, the latter had no power to compel Czernova to produce its Charter. And it was quite within the range of probability that Austria and Prussia, from motives of political jealousy, would decline to co-operate in an affair from which Russia alone was to gain. Therefore, reflecting upon all this, Orloff began to perceive that his plot for the destruction of the Charter, even granting that it had been successfully carried out, was by no means so decisive a blow as he had at first been led to suppose. Czernova might be without its title to autonomy, but this difficulty remained--how were the Czar's ministry to establish the fact? A gleam of cunning suddenly appeared on the face of the envoy. He had solved the problem. "Is it not a part of the coronation-ritual," he asked, "that the original Charter of Catherine shall be placed upon the altar, and that the ruler of Czernova with hand laid upon it shall swear to maintain its provisions?" "That is so," responded the princess; "and we especially invite you, Count, to a seat in the chancel in order that you may witness the ceremony, and set your doubts at rest." "I shall certainly avail myself of the privilege offered me," said Orloff with a peculiar smile, incomprehensible to Barbara, but perfectly understood by at least two persons present. Fear fell upon Paul, if not upon Zabern. Though it might be easy now to equivocate, and to devise plausible excuses for withholding the Charter from the envoy's view, yet on the great day of the coronation, the day that should be the brightest in Barbara's life, the fatal truth would have to be revealed. How was it possible to replace the vital document that had been destroyed by fire! "I have discharged my embassy," said Orloff, bowing. "Count Radzivil," observed Barbara, turning to the premier, "on you devolves the honor of entertaining our guest, Count Feodor Orloff, so long as he shall remain in Czernova." But the envoy, his asperity not at all softened by the princess's courtesy, bluntly averred his intention of setting out for St. Petersburg within an hour from that time. "Loyalty to the Czar forbids me to dally in his service." "The Czar is honored in possessing an envoy so discreet. My lords, we will retire."
