The warrior with whom I struggled upon the stone floor of that dark cell beneath the castle of the Tarids was a man of only ordinary physical strength, and I soon subdued him.

Possibly I accomplished this sooner than I might have otherwise; for, after I got my fingers on his throat, I promised I would not kill him if he would cease his struggling and his attempted screaming.

With me, time was an all-important factor; for even if the man's outcry had not been heard by his comrades above stairs, it seemed quite reasonable that if he did not return to his other duties within a reasonable time, a search for him would be instituted. If I were to escape, I must get out at once; and so, after I made my offer to the man and he ceased his struggling momentarily, I released my grip upon his throat long enough for him to accept or refuse my proposition.

Being a man of intelligence, he accepted.

I immediately bound him with his own harness and, as an added precaution, stuffed a gag in his mouth. Next I relieved him of his dagger, and after groping around on the floor for some time I found the long-sword that had fallen from his hand when I first attacked him.

"And now good-bye, my friend," I said. "You need not feel humiliated at your defeat; far better men than you have gone down before John Carter, Prince of Helium." Then I went out and closed and locked the door of the cell after me.

The corridor was very dark. I had had but one brief glimpse of it, or rather of a portion of it, when my food had been brought to me the previous day.

It had seemed to me then that the corridor led straight away from the entrance to my cell, and now I groped my way through the darkness in that direction.

Probably I should have moved slowly along that unknown passageway; but I did not, for I knew, that if the warrior's cries had been heard in the castle above, there might be an investigation; and I most certainly did not wish to meet a body of armed men in that cul-de-sac.

Keeping one hand against the wall to guide me, I moved rapidly forward; and I had gone perhaps a hundred yards when I discerned a faint suggestion of light ahead of me. It did not seem to be the yellowish light of a torch, but, rather, diffused daylight.

It increased in volume as I approached it, and presently I came to the foot of the stairway down which it was shining.

All this time, I had heard nothing to indicate that anyone was coming to investigate; so it was with a feeling of at least some security that I ascended the stairway.

With the utmost caution, I entered the level above. Here it was much lighter. I was in a short corridor with a doorway on either side; ahead of me the passageway ended in a transverse corridor. I moved quickly forward, for I could now see my way quite clearly, as the corridor, although extremely gloomy, was much better lighted than that from which I had emerged.
