"The cardinal asserted that his nephew was ignorant of the contents of the three packets."

"Good! For my own part I do not think it probable that the cardinal would share so valuable a secret with others; his own self-interest would forbid it. Well, now," mused Zabern, "if we lay violent hands upon Ravenna the nephew over the border will send off the letters."

"That has been my fear."

"On the other hand, if I despatch an agent to the house of Redwitz to obtain possession of the letters, and it would be very easy to effect this—"

"Then Redwitz, discovering his loss, would notify the fact to the cardinal, who would thus become apprised of our design."

"True, princess; therefore our plan is obvious. Either the seizure of the papers and the seizure of the cardinal must take place coincidently, or—But leave it to me, your Highness," added Zabern, breaking off somewhat abruptly. "Let the cardinal enjoy his brief span of life at Rome. As soon as he returns he shall be secretly seized in his own palace, instantly gagged to prevent him from revealing anything even to his captors, and conveyed in a covered carriage to the oubliettes of the Citadel. He shall never see daylight again."

Much as the cardinal might deserve such fate, Barbara nevertheless could not repress a shudder.

"Marshal," she said, with a grave look, "it is a dangerous thing to seize, imprison, and execute a cardinal, a prince of the Church, without any pretence at a trial. The Pope—all Europe—will have something to say on the matter."

"Trial? We dare not try him, for then would he make known to the judges and others the very matter we wish to keep secret. Ours is a dangerous game, true; but it would be far more dangerous to let the villain live. Still, there is no need for his arrest; there are other and safer ways. The cardinal may disappear mysteriously, and then Marshal Zabern, the Minister of Justice, will offer a large reward, ay, and will give it, too, to any one who can tell what has become of the missing archbishop. Or," added Zabern, grimly, "he may be found to have committed suicide in his own palace."

Zabern spoke without the least scruple. He was not naturally cruel nor treacherous, but he reflected that the crown of Czernova was at stake, and with it, so he believed, the future liberation of Poland; and where these weighty matters were concerned, the secret removal of a cardinal was but a light thing in his eyes.
