Lorry was thoughtful for a while. He felt the chill of discouragement in his heart.

"In that case we must lie outside and wait till they come out with the Princess. Then make a sudden a.s.sault and rescue her. In the darkness we can make them think there are a dozen rescuers," he whispered at length.

After a while Anguish asked another appalling question, the outgrowth of brain-racking study:

"Suppose these fellows, who will be in guards' uniform, should turn about and capture us. What then? We are strangers, and our story would not be believed. They could slip away in the excitement and leave us in a very awkward position."

"Harry, if we are going to hatch up all sorts of possibilities, let's give up the thing right now. I have thought of a thousand contingencies, and I realize how desperate the job is to be. We must either cast discretion to the winds or we must retreat. Which shall we do?"

"Cast aside discretion and hang our fears," said the other, once more inspired. "We'll take chances and hope for the best. If we see we are going to fail we can then call for the guards. The grounds are doubtless full of soldiers. The only part I'm worried about is the groping through that strange, dark castle."

"We must do some calculating and we must stick close together. By watching where they station the two Viennese we can figure about what direction we must take to get to the Princess's room. Sh! Isn't that some one approaching?"

They strained their ears for a moment and then involuntarily, spasmodically shook hands, each heaving the deep breath of excitement.

The stealthy rustle of moving bodies was heard, faint, but positive. It was a moment of suspense that would have strained the nerve of a stone image. Where were the abductors? On which side of the road and from what direction did they come? Oh, for the eyes of a cat!

There was a slight shuffling of feet near the gate, a suppressed "Sh?"

and then deathly silence. The gate opened, a faint creaking attesting the fact, followed by the heavy breathing of men, the noise of subdued activity, the scent of chloroform. Some whispering, and then the creaking of the gate.

"They've gone," whispered Anguish. Lorry's form arose to a crouching posture and a moment later he was crossing the road with the tread of a cat, his cane gripped firmly in his hard. Anguish followed with drawn revolver. So still was their approach that they were upon the figure of a man before they were aware of the fact. In the darkness the foremost American saw the outline of a human figure bending over a long object on the ground. He could smell chloroform strongly, and grasped the situation. The Viennese was administering the drug, his companions having left that duty for him to perform. No doubt the treacherous guardsman was lying calmly on his back, bound and gagged, welcoming unconsciousness with a smile of security.

As soon as Lorry gained his bearings fully he prepared to fell the wretch who was to stand watch. Anguish heard his friend's figure suddenly shoot to an erect position. A whirring sound as of disturbed air and then a dull thud. Something rolled over on the ground, and all was still. He was at Lorry's side in an instant.

"I hope I haven't killed him," whispered, Lorry. "Quick! Here is his bottle of ether. Hold it beneath his nose. I am going to pile the body of this guard crosswise on top of him. He will not be able to arise if he should recover consciousness."

All this was done in a moment's time, and the two trackers were headed for the entrance.

The gate was ajar two or three feet. With turbulent hearts, they stole through.

"Keep along the wall," whispered Lorry, "and trust to luck. The castle is to the left."

Without hesitation they crept over the noiseless gra.s.s, close beside the wall. Directly they heard sounds near at hand. The abductors were binding and chloroforming the guard at the arbor. After waiting for some moments they heard the party glide away in the darkness, and followed.

The body of the guard was lying just outside the mouth of the arbor, and the odor of chloroform was almost overpowering. Once inside the long arbor, the Americans moved slowly and with greater caution. There was a dim light in a bas.e.m.e.nt window ahead. Toward the front of the castle and in the second story a faint glow came from another window. They guessed it to be from the Princess' room or from that of the countess.

At last they saw four figures steal past the dim bas.e.m.e.nt light. One of them halted near the window, and three crept away in the darkness.

Presently one of them returned, and all activity was at an end for the time being. How near it was to two o'clock the watchers could not tell.

They only knew that they were within twenty-five feet of Geddos and Ostrom, and that they would not have long to wait.

Soon a bright little blaze of light crossed the bas.e.m.e.nt opening. Then it returned, crossing a second time, and a third. All was still again.

The soft shuffle of a foot, the rustle of arbor vines, and the form of a man crawled up to the window. With inconceivable stealth and carefulness it glided through the aperture, followed by a companion.

Lorry and Anguish were at the opening a second or two later, lying flat on their stomachs and listening for sounds from within. The dim light was still there, the window was open, and there was a sound of whispering. Lorry raised his head and peered through, taking calculations while the light made it possible. He saw an open door on the opposite side of the low room, with steps beyond, leading upward.

Between the window and the door there were no obstacles. Up those steps he saw three men creep, the leader carrying the dim light. The door was left open, doubtless to afford unimpeded exit from the building in case of emergency. Harry Anguish touched Lorry's arm.

"I took the two pistols from that Vienna man out there. We may need them. Here is one for yourself. Go first, Lorry," he whispered.

Lorry stuck the revolver in his coat pocket and gently slid through the window to the floor below. His friend followed, and they paused to listen. Taking Anguish by the hand the other led the way straight to the spot where he remembered seeing the door.

Boldly the two men began the breathless ascent of the stone steps. The top was reached, and far ahead, down a narrow hall, they saw the three men and the dim light moving. Two of them wore uniforms of guards.

Keeping close to the wall their followers crept after them. Up another flight of steps they went, and then through a s.p.a.cious hall. The Americans had no time and no desire to inspect their surroundings. The wide doors at the far side of the room opened softly, and here the trio paused. Down a great marble hallway a dim red light shed its soft glow.

It came from the lamp at the foot of the broad staircase.

The cook pointed to the steps, and then gave his thumb a jerk toward the left. Without the least sign of fear Geddos and Ostrom glided into the hall and made for the staircase. The watchers could not but feel a thrill of admiration for these daring wretches. But now a new danger confronted them. The cook remained standing in the doorway, watching his fellows in crime! How were they to pa.s.s him?

There was no time to be lost. The abductors were creeping up the steps already, and the cook must be disposed of. He had blown out the light which he carried, and was now a very dim shadow. Lorry glided forward and in an instant stood before the amazed fellow, jamming a pistol into his face.

"A sound and you die!" he hissed.

"Don't move!" came another whisper, and a second revolver touched his ear. The cook, perhaps, did not know their language, but he certainly understood its meaning. He trembled, and would have fallen to the floor had not the strong hand of Lorry pinned him to the wall. The hand was on his throat, too.

"Chloroform him, Harry, and don't let him make a sound!" whispered the owner of the hand. Anguish's twitching fingers succeeded those of his friend on the cook's throat, his pistol was returned to his pocket, and the little bottle came again into use.

"I'll go ahead. Follow me as soon as you have finished this fellow. Be careful, and turn to the left when you come to the top."

Lorry was off across the marble floor, headed for the stairway, and Anguish was left in charge of the cook, of whom he was to make short work. Now came the desperate, uncertain part of the transaction. Suppose he were to meet the two conspirators at the head of the stairs, or in the hall, or that the other traitor, Dannox, should appear to frustrate all. It was the most trying moment in the whole life of the reckless Lorry.

When near the top of the steps he hugged the high bal.u.s.trade and cautiously peered ahead. He found himself looking down a long hall, at the far end of which, to his right, a dim light was burning. There was no sound and there was no sign of the two men, either to the right or to the left. His heart felt like lead! They evidently had entered the Princess's room! How was he to find that room? Slowly he wriggled across the broad, dark hall, straightening up in the shadow of a great post.

From this point he edged along the wall for a distance of ten or twelve feet to the left. A sound came from farther down the hall, and he imagined he heard some one approaching.

His hand came in contact with a heavy hanging or tapestry, and he quickly squirmed behind its folds, finding himself against a door which moved as his body touched it. He felt it swing open slightly and drew back, intending to return to the hall, uncertain and very much undecided as to the course to pursue. His revolver was in his hand. Just as he was about to pull aside the curtain a man glided past, quickly followed by another. Providence had kept him from running squarely into them.

They were going toward the left, and he realized that they were now approaching the Princess's room. How he came to be ahead of them he could not imagine. Strange trembling seized his legs, so great was the relief after the narrow escape. Again he felt the door move slightly as he pressed against it. The necessity for a partial recovery of his composure before the next and most important step, impelled him softly to enter the room for an instant's breath.

Holding to the door he stood inside and drew himself to his full height, taking a long and tremulous breath. There was no light in the room, but through the door crack to his left came a dim, broad streak. He now knew where he was. This room was next to that in which the Princess slept, for had he not seen the light from her window? Perhaps he was now in the room of the Countess Dagniar. Next door! Next door! Even now the daring Geddos and Ostrom were crawling towards the bed of the ruler of Graustark, not twenty feet away. His first impulse was to cross and open the door leading to the next room, surmising that it would be unlocked, but he remembered Anguish, who was doubtless, by this time, stealing up the stairs. They must not be separated, for it would require two steady, cool heads to deal with the villains. It was not one man's work. As he turned to leave the room he thought how wonderfully well they had succeeded in the delicate enterprise so far.

His knees struck the door, and there was a dull thump, not loud in reality, but like the report of a gun to him. A sudden rustle in the darkness of the room and then a sleepy voice, soft and quick, as of a woman awakening with a start.

"Who is it?"

His heart ceased beating, his body grew stiff and immovable. Again the voice, a touch of alarm in it now:

"Is that you, Donnox?"

She spoke in German, and the voice came from somewhere in front and to his right. He could not answer, could not move. The paralysis of indecision was upon him.

"How is it that the outer door is open?"

This time there was something like a reprimand in the tones, still low.

He almost could see the wide-open, searching eyes.

X. YETIVE

There could be no further hesitation. Something must be done and instantly. He gently closed the door before answering the third question. In his nervousness he spoke in English, advancing to the middle of the room. Impossible to see the woman to whom he hissed this alarming threat-he only could speculate as to its effect:

"If you utter a sound, madam, I shall kill you. Be calm, and allow me to explain my presence here!"

He expected her to shriek, forgetting that she might not understand his words. Instead there was a deathly silence. Had she swooned? His heart was leaping with hope. But she spoke softly again, tremulously, and in English:
