The boy's eyes had lighted with pleasure as I spoke, and I saw him glance from his rusty trappings to the magnificence of my own. For a moment he stood in thought before he spoke, and for that moment my heart fairly ceased beating-so much for me there was which hung upon the substance of his answer.

"And I went to the palace of the Prince of Helium with any such demand, they would laugh at me and, into the bargain, would more than likely throw me headforemost into the avenue. No, it cannot be, though I thank you for the offer. Why, if Zat Arras even dreamed that I contemplated such a thing he would have my heart cut out of me."

"There can be no harm in it, my boy," I urged. "By night you may go to my palace with a note from me to Carthoris, my son. You may read the note before you deliver it, that you may know that it contains nothing harmful to Zat Arras. My son will be discreet, and so none but us three need know. It is very simple, and such a harmless act that it could be condemned by no one."

Again he stood silently in deep thought.

"And there is a jewelled short-sword which I took from the body of a northern Jeddak. When you get the harness, see that Carthoris gives you that also. With it and the harness which you may select there will be no more handsomely accoutred warrior in all Zodanga.

"Bring writing materials when you come next to my cell, and within a few hours we shall see you garbed in a style befitting your birth and carriage."

Still in thought, and without speaking, he turned and left me. I could not guess what his decision might be, and for hours I sat fretting over the outcome of the matter.

If he accepted a message to Carthoris it would mean to me that Carthoris still lived and was free. If the youth returned wearing the harness and the sword, I would know that Carthoris had received my note and that he knew that I still lived. That the bearer of the note was a Zodangan would be sufficient to explain to Carthoris that I was a prisoner of Zat Arras.

It was with feelings of excited expectancy which I could scarce hide that I heard the youth's approach upon the occasion of his next regular visit. I did not speak beyond my accustomed greeting of him. As he placed the food upon the floor by my side he also deposited writing materials at the same time.

My heart fairly bounded for joy. I had won my point. For a moment I looked at the materials in feigned surprise, but soon I permitted an expression of dawning comprehension to come into my face, and then, picking them up, I penned a brief order to Carthoris to deliver to Parthak a harness of his selection and the short-sword which I described. That was all. But it meant everything to me and to Carthoris.

I laid the note open upon the floor. Parthak picked it up and, without a word, left me.

As nearly as I could estimate, I had at this time been in the pits for three hundred days. If anything was to be done to save Dejah Thoris it must be done quickly, for, were she not already dead, her end must soon come, since those whom Issus chose lived but a single year.

The next time I heard approaching footsteps I could scarce await to see if Parthak wore the harness and the sword, but judge, if you can, my chagrin and disappointment when I saw that he who bore my food was not Parthak.

"What has become of Parthak?" I asked, but the fellow would not answer, and as soon as he had deposited my food, turned and retraced his steps to the world above.

Days came and went, and still my new jailer continued his duties, nor would he ever speak a word to me, either in reply to the simplest question or of his own initiative.

I could only speculate on the cause of Parthak's removal, but that it was connected in some way directly with the note I had given him was most apparent to me. After all my rejoicing, I was no better off than before, for now I did not even know that Carthoris lived, for if Parthak had wished to raise himself in the estimation of Zat Arras he would have permitted me to go on precisely as I did, so that he could carry my note to his master, in proof of his own loyalty and devotion.

Thirty days had passed since I had given the youth the note. Three hundred and thirty days had passed since my incarceration. As closely as I could figure, there remained a bare thirty days ere Dejah Thoris would be ordered to the arena for the rites of Issus.

As the terrible picture forced itself vividly across my imagination, I buried my face in my arms, and only with the greatest difficulty was it that I repressed the tears that welled to my eyes despite my every effort. To think of that beautiful creature torn and rended by the cruel fangs of the hideous white apes! It was unthinkable. Such a horrid fact could not be; and yet my reason told me that within thirty days my incomparable Princess would be fought over in the arena of the First Born by those very wild beasts; that her bleeding corpse would be dragged through the dirt and the dust, until at last a part of it would be rescued to be served as food upon the tables of the black nobles.

I think that I should have gone crazy but for the sound of my approaching jailer. It distracted my attention from the terrible thoughts that had been occupying my entire mind. Now a new and grim determination came to me. I would make one super-human effort to escape. Kill my jailer by a ruse, and trust to fate to lead me to the outer world in safety.

With the thought came instant action. I threw myself upon the floor of my cell close by the wall, in a strained and distorted posture, as though I were dead after a struggle or convulsions. When he should stoop over me I had but to grasp his throat with one hand and strike him a terrific blow with the slack of my chain, which I gripped firmly in my right hand for the purpose.

Nearer and nearer came the doomed man. Now I heard him halt before me. There was a muttered exclamation, and then a step as he came to my side. I felt him kneel beside me. My grip tightened upon the chain. He leaned close to me. I must open my eyes to find his throat, grasp it, and strike one mighty final blow all at the same instant.

The thing worked just as I had planned. So brief was the interval between the opening of my eyes and the fall of the chain that I could not check it, though it that minute interval I recognized the face so close to mine as that of my son, Carthoris.

God! What cruel and malign fate had worked to such a frightful end! What devious chain of circumstances had led my boy to my side at this one particular minute of our lives when I could strike him down and kill him, in ignorance of his identity! A benign though tardy Providence blurred my vision and my mind as I sank into unconsciousness across the lifeless body of my only son.

When I regained consciousness it was to feel a cool, firm hand pressed upon my forehead. For an instant I did not open my eyes. I was endeavouring to gather the loose ends of many thoughts and memories which flitted elusively through my tired and overwrought brain.

At length came the cruel recollection of the thing that I had done in my last conscious act, and then I dared not to open my eyes for fear of what I should see lying beside me. I wondered who it could be who ministered to me. Carthoris must have had a companion whom I had not seen. Well, I must face the inevitable some time, so why not now, and with a sigh I opened my eyes.

Leaning over me was Carthoris, a great bruise upon his forehead where the chain had struck, but alive, thank God, alive! There was no one with him. Reaching out my arms, I took my boy within them, and if ever there arose from any planet a fervent prayer of gratitude, it was there beneath the crust of dying Mars as I thanked the Eternal Mystery for my son's life.

The brief instant in which I had seen and recognized Carthoris before the chain fell must have been ample to check the force of the blow. He told me that he had lain unconscious for a time-how long he did not know.
