"Sire," he said, "the fellow knows that he is already as good as dead, and so in his bravado he dares affront you. He has been convicted of spying by the Austrians. He is still a spy. It is unnecessary to repeat the formality of a trial."

Leopold at last found his voice, though it trembled and broke as he spoke.

"Carry out the sentence of the Austrian court in the morning," he said. "A volley now might arouse the garrison in the town and be misconstrued."

Maenck ordered Barney escorted from the apartment, then he turned toward the king.

"And the other prisoner, sire?" he inquired.

"There is no other prisoner," he said. "Her highness, the Princess von der Tann, is a guest of Prince Peter. She will be escorted to her apartment at once."

"Her highness, the Princess von der Tann, is not a guest of Prince Peter." The girl's voice was low and cold. "If Mr. Custer is a prisoner, her highness, too, is a prisoner. If he is to be shot, she demands a like fate. To die by the side of a MAN would be infinitely preferable to living by the side of your majesty."

Once again Leopold of Lutha reddened. For a moment he paced the room angrily to hide his emotion. Then he turned once to Maenck.

"Escort the prisoner to the north tower," he commanded, "and this insolent girl to the chambers next to ours. Tomorrow we shall talk with her again."

Outside the room Barney turned for a last look at the princess as he was being led in one direction and she in another. A smile of encouragement was on his lips and cold hopelessness in his heart.

She answered the smile and her lips formed a silent "good-bye." They formed something else, too--three words which he was sure he could not have mistaken, and then they parted, he for the death chamber and she for what fate she could but guess.

As his guard halted before a door at the far end of a long corridor Barney Custer sensed a sudden familiarity in his surroundings. He was conscious of that sensation which is common to all of us--of having lived through a scene at some former time, to each minutest detail.

As the door opened and he was pushed into the room he realized that there was excellent foundation for the impression--he immediately recognized the apartment as the same in which he had once before been imprisoned. At that time he had been mistaken for the mad king who had escaped from the clutches of Peter of Blentz. The same king was now visiting as a guest the fortress in which he had spent ten bitter years as a prisoner.

"Say your prayers, my friend," admonished Maenck, as he was about to leave him alone, "for at dawn you die--and this time the firing squad will make a better job of it."

Barney did not answer him, and the captain departed, locking the door after him and leaving two men on guard in the corridor. Alone, Barney looked about the room. It was in no wise changed since his former visit to it. He recalled the incidents of the hour of his imprisonment here, thought of old Joseph who had aided his escape, looked at the paneled fireplace, whose secret, it was evident, not even the master of Blentz was familiar with--and grinned.

"'For at dawn you die!'" he repeated to himself, still smiling broadly. Then he crossed quickly to the fireplace, running his fingers along the edge of one of the large tiled panels that hid the entrance to the well-like shaft that rose from the cellars beneath to the towers above and which opened through similar concealed exits upon each floor. If the floor above should be untenanted he might be able to reach it as he and Joseph had done two years ago when they opened the secret panel in the fireplace and climbed a hidden ladder to the room overhead; and then by vacant corridors reached the far end of the castle above the suite in which the princess had been confined and near which Barney had every reason to believe she was now imprisoned.

Carefully Barney's fingers traversed the edges of the panel. No hidden latch rewarded his search. Again and again he examined the perfectly fitted joints until he was convinced either that there was no latch there or that it was hid beyond possibility of discovery.

With each succeeding minute the American's heart and hopes sank lower and lower. Two years had elapsed since he had seen the secret portal swing to the touch of Joseph's fingers. One may forget much in two years; but that he was at work upon the right panel Barney was positive. However, it would do no harm to examine its mate which resembled it in minutest detail.

Almost indifferently Barney turned his attention to the other panel.

He ran his fingers over it, his eyes following them. What was that?

A finger-print? Upon the left side half way up a tiny smudge was visible. Barney examined it more carefully. A round, white figure of the conventional design that was burned into the tile bore the telltale smudge.

Otherwise it differed apparently in no way from the numerous other round, white figures that were repeated many times in the scheme of decoration. Barney placed his thumb exactly over the mark that another thumb had left there and pushed. The figure sank into the panel beneath the pressure. Barney pushed harder, breathless with suspense. The panel swung in at his effort. The American could have whooped with delight.

A moment more and he stood upon the opposite side of the secret door in utter darkness, for he had quickly closed it after him. To strike a match was but the matter of a moment. The wavering light revealed the top of the ladder that led downward and the foot of another leading aloft. He struck still more matches in search of the rope.

It was not there, but his quest revealed the fact that the well at this point was much larger than he had imagined--it broadened into a small chamber.

The light of many matches finally led him to the discovery of a pa.s.sageway directly behind the fireplace. It was narrow, and after spanning the chimney descended by a few rough steps to a slightly lower level. It led toward the opposite end of the castle. Could it be possible that it connected directly with the apartments in the farther tower--in the tower where the king was and the Princess Emma? Barney could scarce hope for any such good luck, but at least it was worth investigating--it must lead somewhere.

He followed it warily, feeling his way with hands and feet and occasionally striking a match. It was evident that the corridor lay in the thick wall of the castle, midway between the bottoms of the windows of the second floor and the tops of those upon the first--this would account for the slightly lower level of the pa.s.sage from the floor of the second story.

Barney had traversed some distance in the darkness along the forgotten corridor when the sound of voices came to him from beyond the wall at his right. He stopped, motionless, pressing his ear against the side wall. As he did so he became aware of the fact that at this point the wall was of wood--a large panel of hardwood. Now he could hear even the words of the speaker upon the opposite side.

"Fetch her here, captain, and I will talk with her alone." The voice was the king's. "And, captain, you might remove the guard from before the door temporarily. I shall not require them, nor do I wish them to overhear my conversation with the princess."

Barney could hear the officer acknowledge the commands of the king, and then he heard a door close. The man had gone to fetch the princess. The American struck a match and examined the panel before him. It reached to the top of the pa.s.sageway and was some three feet in width.

At one side were three hinges, and at the other an ancient spring lock. For an instant Barney stood in indecision. What should he do?

His entry into the apartments of the king would result in alarming the entire fortress. Were he sure the king was alone it might be accomplished. Should he enter now or wait until the Princess Emma had been brought to the king?

With the question came the answer--a bold and daring scheme. His fingers sought the lock. Very gently, he unlatched it and pushed outward upon the panel. Suddenly the great doorway gave beneath his touch. It opened a crack letting a flood of light into his dark cell that almost blinded him.

For a moment he could see nothing, and then out of the glaring blur grew the figure of a man sitting at a table--with his back toward the panel.

It was the king, and he was alone. Noiselessly Barney Custer entered the apartment, closing the panel after him. At his back now was the great oil painting of the Blentz princess that had hid the secret entrance to the room. He crossed the thick rugs until he stood behind the king. Then he clapped one hand over the mouth of the monarch of Lutha and threw the other arm about his neck.

"Make the slightest outcry and I shall kill you," he whispered in the ear of the terrified man.

Across the room Barney saw a revolver lying upon a small table. He raised the king to his feet and, turning his back toward the weapon dragged him across the apartment until the table was within easy reach. Then he s.n.a.t.c.hed up the revolver and swung the king around into a chair facing him, the muzzle of the gun pressed against his face.

"Silence," he whispered.

The king, white and trembling, gasped as his eyes fell upon the face of the American.

"You?" His voice was barely audible.

"Take off your clothes--every st.i.tch of them--and if any one asks for admittance, deny them. Quick, now," as the king hesitated. "My life is forfeited unless I can escape. If I am apprehended I shall see that you pay for my recapture with your life--if any one enters this room without my sanction they will enter it to find a dead king upon the floor; do you understand?"

The king made no reply other than to commence divesting himself of his clothing. Barney followed his example, but not before he had crossed to the door that opened into the main corridor and shot the bolt upon the inside. When both men had removed their clothing Barney pointed to the little pile of soiled peasant garb that he had worn.

"Put those on," he commanded.

The king hesitated, drawing back in disgust. Barney paused, half-way into the royal union suit, and leveled the revolver at Leopold. The king picked up one of the garments gingerly between the tips of his thumb and finger.

"Hurry!" admonished the American, drawing the silk half-hose of the ruler of Lutha over his foot. "If you don't hurry," he added, "someone may interrupt us, and you know what the result would be--to you."

Scowling, Leopold donned the rough garments. Barney, fully clothed in the uniform the king had been wearing, stepped across the apartment to where the king's sword and helmet lay upon the side table that had also borne the revolver. He placed the helmet upon his head and buckled the sword-belt about his waist, then he faced the king, behind whom was a cheval gla.s.s. In it Barney saw his image. The king was looking at the American, his eyes wide and his jaw dropped. Barney did not wonder at his consternation. He himself was dumbfounded by the likeness which he bore to the king. It was positively uncanny. He approached Leopold.

"Remove your rings," he said, holding out his hand. The king did as he was bid, and Barney slipped the two baubles upon his fingers. One of them was the royal ring of the kings of Lutha.

The American now blindfolded the king and led him toward the panel which had given him ingress to the room. Through it the two men pa.s.sed, Barney closing the panel after them. Then he conducted the king back along the dark pa.s.sageway to the room which the American had but recently quitted. At the back of the panel which led into his former prison Barney halted and listened. No sound came from beyond the part.i.tion. Gently Barney opened the secret door a trifle--just enough to permit him a quick survey of the interior of the apartment. It was empty. A smile crossed his face as he thought of the difficulty Leopold might encounter the following morning in convincing his jailers that he was not the American.

Then he recalled his reflection in the cheval gla.s.s and frowned.

Could Leopold convince them? He doubted it--and what then? The American was sentenced to be shot at dawn. They would shoot the king instead. Then there would be none to whom to return the kingship.

What would he do with it? The temptation was great. Again a throne lay within his grasp--a throne and the woman he loved. None might ever know unless he chose to tell--his resemblance to Leopold was too perfect. It defied detection.

With an exclamation of impatience he wheeled about and dragged the frightened monarch back to the room from which he had stolen him. As he entered he heard a knock at the door.

"Do not disturb me now," he called. "Come again in half an hour."

"But it is Her Highness, Princess Emma, sire," came a voice from beyond the door. "You summoned her."

"She may return to her apartments," replied Barney.
