"I cannot kill her," said Astok. "Issus! I cannot do it! When she turns those eyes upon me my heart becomes water."

Vas Kor's eyes narrowed.

"And you wish--" He paused, the interrogation unfinished, yet complete.

Astok nodded.

"YOU do not love her," he said.

"But I love my life--though I am only a lesser n.o.ble," he concluded meaningly.

"You shall be a greater n.o.ble--a n.o.ble of the first rank!" exclaimed Astok.

"I would be a jed," said Vas Kor bluntly.

Astok hesitated.

"A jed must die before there can be another jed," he pleaded.

"Jeds have died before," snapped Vas Kor. "It would doubtless be not difficult for you to find a jed you do not love, Astok--there are many who do not love you."

Already Vas Kor was commencing to presume upon his power over the young prince. Astok was quick to note and appreciate the subtle change in his lieutenant. A cunning scheme entered his weak and wicked brain.

"As you say, Vas Kor!" he exclaimed. "You shall be a jed when the thing is done," and then, to himself: "Nor will it then be difficult for me to find a jed I do not love."

"When shall we return to Dusar?" asked the n.o.ble.

"At once," replied Astok. "Let us get under way now--there is naught to keep you here?"

"I had intended sailing on the morrow, picking up such recruits as the various Dwars of the Roads might have collected for me, as we returned to Dusar."

"Let the recruits wait," said Astok. "Or, better still, come you to Dusar upon the Thuria, leaving the Kalksus to follow and pick up the recruits."

"Yes," acquiesced Vas Kor; "that is the better plan. Come; I am ready," and he rose to accompany Astok to the latter's flier.

The listener at the ventilator came to his feet slowly, like an old man. His face was drawn and pinched and very white beneath the light copper of his skin. She was to die! And he helpless to avert the tragedy. He did not even know where she was imprisoned.

The two men were ascending from the cabin to the deck. Turjun, the panthan, crept close to the companionway, his sinuous fingers closing tightly upon the hilt of his dagger. Could he despatch them both before he was overpowered? He smiled. He could slay an entire utan of her enemies in his present state of mind.

They were almost abreast of him now. Astok was speaking.

"Bring a couple of your men along, Vas Kor," he said. "We are short-handed upon the Thuria, so quickly did we depart."

The panthan's fingers dropped from the dagger's hilt. His quick mind had grasped here a chance for succouring Thuvia of Ptarth. He might be chosen as one to accompany the a.s.sa.s.sins, and once he had learned where the captive lay he could dispatch Astok and Vas Kor as well as now. To kill them before he knew where Thuvia was hid was simply to leave her to death at the hands of others; for sooner or later Nutus would learn her whereabouts, and Nutus, Jeddak of Dusar, could not afford to let her live.

Turjun put himself in the path of Vas Kor that he might not be overlooked. The n.o.ble aroused the men sleeping upon the deck, but always before him the strange panthan whom he had recruited that same day found means for keeping himself to the fore.

Vas Kor turned to his lieutenant, giving instruction for the bringing of the Kalksus to Dusar, and the gathering up of the recruits; then he signed to two warriors who stood close behind the padwar.

"You two accompany us to the Thuria," he said, "and put yourselves at the disposal of her dwar."

It was dark upon the deck of the Kalksus, so Vas Kor had not a good look at the faces of the two he chose; but that was of no moment, for they were but common warriors to a.s.sist with the ordinary duties upon a flier, and to fight if need be.

One of the two was Kar Komak, the bowman. The other was not Carthoris.

The Heliumite was mad with disappointment. He s.n.a.t.c.hed his dagger from his harness; but already Astok had left the deck of the Kalksus, and he knew that before he could overtake him, should he dispatch Vas Kor, he would be killed by the Dusarian warriors, who now were thick upon the deck. With either one of the two alive Thuvia was in as great danger as though both lived--it must be both!

As Vas Kor descended to the ground Carthoris boldly followed him, nor did any attempt to halt him, thinking, doubtless, that he was one of the party.

After him came Kar Komak and the Dusarian warrior who had been detailed to duty upon the Thuria. Carthoris walked close to the left side of the latter. Now they came to the dense shadow under the side of the Thuria. It was very dark there, so that they had to grope for the ladder.

Kar Komak preceded the Dusarian. The latter reached upward for the swinging rounds, and as he did so steel fingers closed upon his windpipe and a steel blade pierced the very centre of his heart.

Turjun, the panthan, was the last to clamber over the rail of the Thuria, drawing the rope ladder in after him.

A moment later the flier was rising rapidly, headed for the north.

At the rail Kar Komak turned to speak to the warrior who had been detailed to accompany him. His eyes went wide as they rested upon the face of the young man whom he had met beside the granite cliffs that guard mysterious Lothar. How had he come in place of the Dusarian?

A quick sign, and Kar Komak turned once more to find the Thuria's dwar that he might report himself for duty. Behind him followed the panthan.

Carthoris blessed the chance that had caused Vas Kor to choose the bowman of all others, for had it been another Dusarian there would have been questions to answer as to the whereabouts of the warrior who lay so quietly in the field beyond the residence of Hal Vas, Dwar of the Southern Road; and Carthoris had no answer to that question other than his sword point, which alone was scarce adequate to convince the entire crew of the Thuria.

The journey to Dusar seemed interminable to the impatient Carthoris, though as a matter of fact it was quickly accomplished. Some time before they reached their destination they met and spoke with another Dusarian war flier. From it they learned that a great battle was soon to be fought south-east of Dusar.

The combined navies of Dusar, Ptarth and Kaol had been intercepted in their advance toward Helium by the mighty Heliumitic navy--the most formidable upon Barsoom, not alone in numbers and armament, but in the training and courage of its officers and warriors, and the zitidaric proportions of many of its monster battleships.

Not for many a day had there been the promise of such a battle. Four jeddaks were in direct command of their own fleets--Kulan t.i.th of Kaol, Thuvan Dihn of Ptarth, and Nutus of Dusar upon one side; while upon the other was Tardos Mors, Jeddak of Helium. With the latter was John Carter, Warlord of Mars.

From the far north another force was moving south across the barrier cliffs--the new navy of Talu, Jeddak of Okar, coming in response to the call from the warlord. Upon the decks of the sullen ships of war black-bearded yellow men looked over eagerly toward the south. Gorgeous were they in their splendid cloaks of orluk and apt. Fierce, formidable fighters from the hothouse cities of the frozen north.

And from the distant south, from the sea of Omean and the cliffs of gold, from the temples of the therns and the garden of Issus, other thousands sailed into the north at the call of the great man they all had learned to respect, and, respecting, love. Pacing the flagship of this mighty fleet, second only to the navy of Helium, was the ebon G.o.dar, Jeddak of the First Born, his heart beating strong in antic.i.p.ation of the coming moment when he should hurl his savage crews and the weight of his mighty ships upon the enemies of the warlord.

But would these allies reach the theatre of war in time to be of avail to Helium? Or, would Helium need them?

Carthoris, with the other members of the crew of the Thuria, heard the gossip and the rumours. None knew of the two fleets, the one from the south and the other from the north, that were coming to support the ships of Helium, and all of Dusar were convinced that nothing now could save the ancient power of Helium from being wiped for ever from the upper air of Barsoom.

Carthoris, too, loyal son of Helium that he was, felt that even his beloved navy might not be able to cope successfully with the combined forces of three great powers.

Now the Thuria touched the landing-stage above the palace of Astok. Hurriedly the prince and Vas Kor disembarked and entered the drop that would carry them to the lower levels of the palace.

Close beside it was another drop that was utilized by common warriors. Carthoris touched Kar Komak upon the arm.

"Come!" he whispered. "You are my only friend among a nation of enemies. Will you stand by me?"

"To the death," replied Kar Komak.

The two approached the drop. A slave operated it.

"Where are your pa.s.ses?" he asked.

Carthoris fumbled in his pocket pouch as though in search of them, at the same time entering the cage. Kar Komak followed him, closing the door. The slave did not start the cage downward. Every second counted. They must reach the lower level as soon as possible after Astok and Vas Kor if they would know whither the two went.

Carthoris turned suddenly upon the slave, hurling him to the opposite side of the cage.

"Bind and gag him, Kar Komak!" he cried.

Then he grasped the control lever, and as the cage shot downward at sickening speed, the bowman grappled with the slave. Carthoris could not leave the control to a.s.sist his companion, for should they touch the lowest level at the speed at which they were going, all would be dashed to instant death.

Below him he could now see the top of Astok's cage in the parallel shaft, and he reduced the speed of his to that of the other. The slave commenced to scream.

"Silence him!" cried Carthoris.

A moment later a limp form crumpled to the floor of the cage.

"He is silenced," said Kar Komak.

Carthoris brought the cage to a sudden stop at one of the higher levels of the palace. Opening the door, he grasped the still form of the slave and pushed it out upon the floor. Then he banged the gate and resumed the downward drop.

Once more he sighted the top of the cage that held Astok and Vas Kor. An instant later it had stopped, and as he brought his car to a halt, he saw the two men disappear through one of the exits of the corridor beyond.

CHAPTER XIV.

KULAN t.i.tH'S SACRIFICE.

The morning of the second day of her incarceration in the east tower of the palace of Astok, Prince of Dusar, found Thuvia of Ptarth waiting in dull apathy the coming of the a.s.sa.s.sin.

She had exhausted every possibility of escape, going over and over again the door and the windows, the floor and the walls.

The solid ersite slabs she could not even scratch; the tough Barsoomian gla.s.s of the windows would have shattered to nothing less than a heavy sledge in the hands of a strong man. The door and the lock were impregnable. There was no escape. And they had stripped her of her weapons so that she could not even antic.i.p.ate the hour of her doom, thus robbing them of the satisfaction of witnessing her last moments.

When would they come? Would Astok do the deed with his own hands? She doubted that he had the courage for it. At heart he was a coward--she had known it since first she had heard him brag as, a visitor at the court of her father, he had sought to impress her with his valour.

She could not help but compare him with another. And with whom would an affianced bride compare an unsuccessful suitor? With her betrothed? And did Thuvia of Ptarth now measure Astok of Dusar by the standards of Kulan t.i.th, Jeddak of Kaol?

She was about to die; her thoughts were her own to do with as she pleased; yet furthest from them was Kulan t.i.th. Instead the figure of the tall and comely Heliumite filled her mind, crowding therefrom all other images.

She dreamed of his n.o.ble face, the quiet dignity of his bearing, the smile that lit his eyes as he conversed with his friends, and the smile that touched his lips as he fought with his enemies--the fighting smile of his Virginian sire.

And Thuvia of Ptarth, true daughter of Barsoom, found her breath quickening and heart leaping to the memory of this other smile--the smile that she would never see again. With a little half-sob the girl sank to the pile of silks and furs that were tumbled in confusion beneath the east windows, burying her face in her arms.

In the corridor outside her prison-room two men had paused in heated argument.

"I tell you again, Astok," one was saying, "that I shall not do this thing unless you be present in the room."

There was little of the respect due royalty in the tone of the speaker's voice. The other, noting it, flushed.

"Do not impose too far upon my friendship for you, Vas Kor," he snapped. "There is a limit to my patience."

"There is no question of royal prerogative here," returned Vas Kor. "You ask me to become an a.s.sa.s.sin in your stead, and against your jeddak's strict injunctions. You are in no position, Astok, to dictate to me; but rather should you be glad to accede to my reasonable request that you be present, thus sharing the guilt with me. Why should I bear it all?"

The younger man scowled, but he advanced toward the locked door, and as it swung in upon its hinges, he entered the room beyond at the side of Vas Kor.

Across the chamber the girl, hearing them enter, rose to her feet and faced them. Under the soft copper of her skin she blanched just a trifle; but her eyes were brave and level, and the haughty tilt of her firm little chin was eloquent of loathing and contempt.

"You still prefer death?" asked Astok.

"To YOU, yes," replied the girl coldly.

The Prince of Dusar turned to Vas Kor and nodded. The n.o.ble drew his short-sword and crossed the room toward Thuvia.

"Kneel!" he commanded.

"I prefer to die standing," she replied.

"As you will," said Vas Kor, feeling the point of his blade with his left thumb. "In the name of Nutus, Jeddak of Dusar!" he cried, and ran quickly toward her.

"In the name of Carthoris, Prince of Helium!" came in low tones from the doorway.

Vas Kor turned to see the panthan he had recruited at his son's house leaping across the floor toward him. The fellow brushed past Astok with an: "After him, you--calot!"

Vas Kor wheeled to meet the charging man.

"What means this treason?" he cried.

Astok, with bared sword, leaped to Vas Kor's a.s.sistance. The panthan's sword clashed against that of the n.o.ble, and in the first encounter Vas Kor knew that he faced a master swordsman.

Before he half realized the stranger's purpose he found the man between himself and Thuvia of Ptarth, at bay facing the two swords of the Dusarians. But he fought not like a man at bay. Ever was he the aggressor, and though always he kept his flashing blade between the girl and her enemies, yet he managed to force them hither and thither about the room, calling to the girl to follow close behind him.

Until it was too late neither Vas Kor nor Astok dreamed of that which lay in the panthan's mind; but at last as the fellow stood with his back toward the door, both understood--they were penned in their own prison, and now the intruder could slay them at his will, for Thuvia of Ptarth was bolting the door at the man's direction, first taking the key from the opposite side, where Astok had left it when they had entered.

Astok, as was his way, finding that the enemy did not fall immediately before their swords, was leaving the brunt of the fighting to Vas Kor, and now as his eyes appraised the panthan carefully they presently went wider and wider, for slowly he had come to recognize the features of the Prince of Helium.

The Heliumite was pressing close upon Vas Kor. The n.o.ble was bleeding from a dozen wounds. Astok saw that he could not for long withstand the cunning craft of that terrible sword hand.

"Courage, Vas Kor!" he whispered in the other's ear. "I have a plan. Hold him but a moment longer and all will be well," but the balance of the sentence, "with Astok, Prince of Dusar," he did not voice aloud.

Vas Kor, dreaming no treachery, nodded his head, and for a moment succeeded in holding Carthoris at bay. Then the Heliumite and the girl saw the Dusarian prince run swiftly to the opposite side of the chamber, touch something in the wall that sent a great panel swinging inward, and disappear into the black vault beyond.

It was done so quickly that by no possibility could they have intercepted him. Carthoris, fearful lest Vas Kor might similarly elude him, or Astok return immediately with reinforcements, sprang viciously in upon his antagonist, and a moment later the headless body of the Dusarian n.o.ble rolled upon the ersite floor.
