Safe from observation in the high tower above them, I watched the party as it emerged from the hollow of the harbor and rode out upon the avenue below me, and then for the first time I noted a small figure seated in front of one of the warriors. Darkness was coming swiftly now, but before the little cavalcade passed out of sight momentarily behind the corner of the building, as it entered another avenue leading toward the heart of the city, I thought that I recognized the little figure as that of a woman of my own race. That she was a captive was a foregone conclusion and I could not but shudder as I contemplated the fate that lay in store for her. Perhaps my own Sanoma Tora was in equal jeopardy. Perhaps—but no, that could not be possible—how could Sanoma Tora have fallen into the clutches of warriors of the fierce horde of Torquas?

It could not be she. No, that was impossible. But the fact remained that the captive was a red woman, and whether she were Sanoma Tora or another, whether she were from Helium or Jahar, my heart went out in sympathy to her and I forgot my own predicament as something within me urged me to pursue her captors and seek to snatch her from them; but, alas, how futile seemed my fancy. How might I, who might not even save himself, aspire to the rescue of another?

The thought galled me, it hurt my pride, and forthwith I determined that if I would not chance dying to save myself, I might at least chance it for a woman of my own race, and always in the back of my head was the thought that perhaps the object of my solicitude might, indeed, be the woman I loved.

Darkness had fallen as I pressed my ear again to the trap door. All was silent below so that presently I became assured that the creature had departed. Perhaps he was lying in wait for me further down, but what of that? I must face him eventually if he elected to remain. I loosened my pistol in its holster and was upon the point of slipping the bar that secured the door when I distinctly heard the beast directly beneath me.

For an instant I paused. What was the use? It meant certain death to raise that door, and in what way might I be profiting either myself or the poor captive if I gave my life thus uselessly? But there was an alternative—one that I had been planning to adopt in case of necessity from the moment that I had first examined the exterior construction of the tower. It offered a slender chance of escape from my predicament and even a very slender chance was better than what would confront me should I raise the trap door.

I stepped to one of the windows of the tower and looked down upon the city. Neither moon was in the sky; I could see nothing. Toward the interior of the city I heard the squealing of thoats. There would the camp of the green men be located. Thus by the squealing of their vicious mounts would I be guided to it. Again a hunting banth roared in the hills. I sat upon the sill and swung both legs across and then turning on my belly slipped silently over the edge until I hung only by my hands. Groping with my sandaled toes, I felt for a foothold upon the deep-cut carvings of the tower's face. Above me was a blue-black void shot with stars; below me a blank and empty void. It might have been a thousand sofads to the roof below me, or it might have been one; but though I could see nothing I knew that it was one hundred and fifty and that at the bottom lay death if a foot or a hand slipped.

In daylight the sculpturing had seemed large and deep and bold, but by night how different! My toes seemed to find but hollow scratches in a smooth surface of polished stone. My arms and fingers were tiring. I must find a foothold or fall, and then, when hope seemed gone, the toe of my right sandal slipped into a horizontal groove and an instant later my left found a hold.

Flattened against the sheer wall of the tower I lay there resting my tired fingers and arms for a moment and when I felt that they would bear my weight again I sought for hand holds. Thus painfully, perilously, monotonously, I descended inch by inch. I avoided the windows, which naturally greatly increased the difficulty and danger of my descent; yet I did not care to pass directly in front of them for fear that by chance the ape might have descended from the summit of the ladder and would see me.

I cannot recall that ever in my life I felt more alone than I did that night as I was descending the ancient beacon-tower of that deserted city for not even hope was with me. So precarious were my holds upon the rough stone that my fingers were soon numb and exhausted. How they clung at all to those shallow cuts, I do not know. The only redeeming feature of the descent was the darkness, and a hundred times I blessed my first ancestors that I could not see the dizzy depths below me; but on the other hand it was so dark that I could not tell how far I had descended; nor did I dare to look up where the summit of the tower must have been silhouetted against the starlit sky for fear that in doing so I should lose my balance and be precipitated to the courtyard or the roof below. The air of Barsoom is thin; it does not greatly diffuse the starlight, and so, while the heavens above were shot with brilliant points of light, the ground beneath was obliterated in darkness.

Yet I must have been nearer the roof than I thought when that happened which I had been assiduously endeavoring to prevent—the scabbard of my long sword pattered noisily against the face of the tower. In the darkness and the silence it seemed a veritable din, but, however exaggerated it might appear to me, I knew that it was sufficient to reach the ears of the great ape in the tower. Whether a suggestion of its import would occur to him, I could not guess—I could only hope that he would be too dull to connect it with me or my escape.
