Edgar Rice Burroughs: A Princess of Mars

2. CHAPTER II: THE ESCAPE OF THE DEAD (continued)

Suddenly a low but distinct moaning sound issued from the recesses of the cave behind me, and, as it reached the ears of the Indians, they turned and fled in terror, panic-stricken. So frantic were their efforts to escape from the unseen thing behind me that one of the braves was hurled headlong from the cliff to the rocks below. Their wild cries echoed in the canyon for a short time, and then all was still once more.

The sound which had frightened them was not repeated, but it had been sufficient as it was to start me speculating on the possible horror which lurked in the shadows at my back. Fear is a relative term and so I can only measure my feelings at that time by what I had experienced in previous positions of danger and by those that I have passed through since; but I can say without shame that if the sensations I endured during the next few minutes were fear, then may God help the coward, for cowardice is of a surety its own punishment.

To be held paralyzed, with one's back toward some horrible and unknown danger from the very sound of which the ferocious Apache warriors turn in wild stampede, as a flock of sheep would madly flee from a pack of wolves, seems to me the last word in fearsome predicaments for a man who had ever been used to fighting for his life with all the energy of a powerful physique.

Several times I thought I heard faint sounds behind me as of somebody moving cautiously, but eventually even these ceased, and I was left to the contemplation of my position without interruption. I could but vaguely conjecture the cause of my paralysis, and my only hope lay in that it might pass off as suddenly as it had fallen upon me.

Late in the afternoon my horse, which had been standing with dragging rein before the cave, started slowly down the trail, evidently in search of food and water, and I was left alone with my mysterious unknown companion and the dead body of my friend, which lay just within my range of vision upon the ledge where I had placed it in the early morning.
