"What chance have I for life?" he sneered, casting an ugly look towards Dar Tarus.

"You have every chance," I replied. "Your life lies in the hollow of my hand; and you serve me well it shall be yours, though in your own body and not in that belonging to Dar Tarus."

"You do not intend destroying me?"

"Neither you nor Xaxa," I answered. "Xaxa shall live on in her own body and you in yours."

"I do not wish to live in my own body," snapped the Jeddara.

Dar Tarus stood looking at Sag Or-looking at his own body like some disembodied soul-as weird a situation as I have ever encountered.

"Tell me, Sag Or," he said, "what has become of Kara Vasa. When my body has been restored to me and yours to you I shall hold no enmity against you if you have not harmed Kara Vasa and will tell me where she be."

"I cannot tell you, for I do not know. She was not harmed, but the day after you were assassinated she disappeared from Phundahl. We were positive that she was spirited away by her father, but from him we could learn nothing. Then he was assassinated," the man glanced at Xaxa, "and since, we have learned nothing. A slave told us that Kara Vasa, with some of her father's warriors, had embarked upon a flier and set out for Helium, where she purposed placing herself under the protection of the great War Lord of Barsoom; but of the truth of that we know nothing. This is the truth. I, Sag Or, have spoken!" It was futile then to search Phundahl for Kara Vasa and so we held our course towards the east and the Tower of Thavas.

All that night we sped beneath the hurtling moons of Mars, as strange a company as was ever foregathered upon any planet, I will swear. Two men, each possessing the body of the other, an old and wicked empress whose fair body belonged to a youthful damsel beloved by another of this company, a great white ape dominated by half the brain of a human being, and I, a creature of a distant planet, with Gor Hajus, the Assassin of Toonol, completed the mad roster.

I could scarce keep my eyes from the fair form and face of Xaxa, and it is well that I was thus fascinated for I caught her in the act of attempting to hurl herself overboard, so repugnant to her was the prospect of living again in her own old and hideous corpse. After that I kept her securely bound and fastened to the deck though it hurt me to see the bonds upon those fair limbs.

Dar Tarus was almost equally fascinated by the contemplation of his own body, which he had not seen for many years.

"By my first ancestor," he ejaculated. "It must be that I was the least vain of fellows, for I give you my word I had no idea that I was so fair to look upon. I can say this now without seeming egotism, since I am speaking of Sag Or," and he laughed aloud at his little joke.

But the fact remained that the body and face of Dar Tarus were beautiful indeed, though there was a hint of steel in the eyes and the set of the jaw that betokened fighting blood. Little wonder, then, that his own, which Dar Tarus now possessed, was marked by dissipation and age; nor that Dar Tarus yearned to come again into his own.

Just before dawn we dropped to one of the numerous small islands that dot the Great Toonolian Marshes and nosing the ship between the boles of great trees we came to rest upon the surface of the ground, half buried in the lush and gorgeous jungle grasses, well hidden from the sight of possible pursuers. Here Hovan Du found fruits and nuts for us which the simian section of his brain pronounced safe for human consumption, and instinct led him to a nearby spring from which there bubbled delicious water. We four were half famished and much fatigued, so that the food and water were most welcome to us; nor did Xaxa and Sag Or refuse them. Having eaten, three of us lay down upon the ship's deck to sleep, after securely chaining our prisoners, while the fourth stood watch. In this way, taking turns, we slept away most of the day and when night fell, rested and refreshed, we were ready to resume our flight.

Making a wide detour to the south we avoided Toonol and about two hours before dawn we sighted the high Tower of Thavas. I think we were all keyed up to the highest pitch of excitement, for there was not one aboard that flier but whose whole life would be seriously affected by the success or failure of our venture.

As a first precaution we secured the hands of Xaxa and Sag Or behind their backs and placed gags in their mouths, lest they succeed in giving warning of our approach.

Cluros had long since set and Thuria was streaming towards the horizon as we stopped our motor and drifted without lights a mile or two south of the tower while we waited impatiently for Thuria to leave the heavens to darkness and the world to us. To the northwest the lights of Toonol shone plainly against the dark background of the windows of the great laboratory of Ras Thavas, but the tower itself was dark from plinth to pinnacle.

And now the nearer moon dropped plummetlike beneath the horizon and left the scene to darkness and to us. Dar Tarus started the motor, the wonderful, silent motor of Barsoom, and we moved slowly, close to the ground, towards Ras Thavas' island, with no sound other than the gentle whirring of our propeller; nor could that have been heard scarce a hundred feet so slowly was it turning. Close off the island we came to a stop behind a cluster of giant trees and Hovan Du, going into the bow, uttered a few low growls. Then we stood waiting in silence, listening. There was a rustling in the dense undergrowth upon the shore. Again Hovan Du voiced his low, grim call and this time there came an answer from the black shadows. Hovan Du spoke in the language of the great apes and the invisible creature replied.

For five minutes, during which time we were aware from the different voices that others had joined in the conversation from the shore, the apes conversed, and then Hovan Du turned to me.

"It is arranged," he said. "They will permit us to hide our ship beneath these trees and they will permit us to pass out again when we are ready and board her, nor will they harm us in any way. All they ask is that when we are through we shall leave the gate open that leads to the inner court."

"Do they understand that while an ape goes in with us none will return with us?"

I asked.

"Yes; but they will not harm us."

"Why do they wish the gate left open?"

"Do not inquire too closely, Vad Varo," replied Hovan Du. "It should be enough that the great apes make it possible for you to restore Valla Dia's body to her brain and escape with her from this terrible place."

"It is enough," I replied. "When may we land?"

"At once. They will help us drag the ship beneath the trees and make her fast."

"But first we must top the wall to the inner court," I reminded him.

"Yes, true-I had forgotten that we cannot open the gate from this side."

He spoke again, then, to the apes, whom we had not yet seen; and then he told us that all was arranged and that he and Dar Tarus would return with the ship after landing us inside the wall.

Again we got under way and rising slowly above the outer wall dropped silently to the courtyard beyond. The night was unusually dark, clouds having followed Thuria and blotted out the stars after the moon had set. No one could have seen the ship at a distance of fifty feet, and we moved almost without noise. Quietly we lowered our prisoners over the side and Gor Hajus and I remained with them while Dar Tarus and Hovan Du rose again and piloted the ship back to its hiding place.

I moved at once to the gate and, unlatching it, waited. I heard nothing. Never, I think, have I endured such utter silence. There came no sound from the great pile rising behind me, nor any from the dark jungle beyond the wall. Dimly I could see the huddled forms of Gor Hajus, Xaxa and Sag Or beside me-otherwise I might have been alone in the darkness and immensity of space.
