Now these rocks were of an odd formation; quite different from their appearance as seen from below. That front view of them, as I might call it, had shown them as two great rocks with a passageway between them. But on closer view, I saw that one rock leaned against the other (save at the entrance) so that the narrow passage was not only between precipitous walls, but was roofed also by the meeting of these walls above. The falling of one rock against the other had made a sort of triangular passage with the converging walls touching the head as one passed through.
Into this narrow pass the storm had not penetrated, and I later found that the crevice between the two rocks was completely overgrown outside. But the narrow pass was dank and mossy and frequented by little lizards that paused, heads upraised, then scooted this way and that. If human-kind had ever used this passage in following a trail, there certainly was no sign of a trail at the time of my inspection. The ground was rocky so that one might pass through the entire length of a dozen yards or so without stepping on earth. But there was one little area of earth, hard but with a thin mossy surface, or rather hardened scum. It was as if moss had started to grow there, but had not developed; a thin, damp crust of vegetation, compact but sensitive to pressure.
Upon this natural film some living being had laid a naked foot, and all the beating fury of the drenching storm, and of other storms for aught I knew, had not obliterated it. What I noticed particularly about it was that running diagonally across the ball of the foot was an irregular mark which identified the footprint with the one I had seen permanently embedded in the concrete of the McClintick lodge on the first night of our arrival at Leatherstocking Camp.
Then suddenly, before my consternation had subsided, I noticed some crude lettering on the rocky wall of the passage. If the letters were intended to form a word their irregular size and positions suggested an erratic, not to say irrational, procedure in the work. Yet large and small and tilted crazily as they were, they were still in proper order to form the appalling word STRANGLE.
I recalled with a shudder that Harrison McClintick had met his tragic end at the hands of an unknown strangler.
CHAPTER XIII—THE STEADY GAZE
I retraced my difficult way down the mountain, scratched, soaking, and utterly weary. The lodge, which had seemed gloomy enough before, was a cheery refuge now. I was all but unnerved by a sense of mystery and of things dark and inexplicable. Some strange, brooding shadow hovered over this camp; the place was uncanny. I aroused myself and ascribed it to the storm, to the rain-swept wilderness. After all, where was there any mystery?
Some one at camp had once inadvertently stepped on the hearth before the concrete was dry. That it was the imprint of a bare foot had no significance. One about to go in the lake, or returning from it, might have carelessly stepped on the new hearth. And might not that same habitue of camp have gone exploring up the mountain. But barefoot? That seemed unlikely. And how about the rustic brace upon the tree? Could that have been there two or three years and retained its freshness and pliancy? And the targets with their telltale bullet holes; four on each target? And their disappearance? Had all these things a relation to each other?
I roused myself to the wholesome conviction that the haunting specter of the tragedy and the demon of the storm were playing pranks with my fancy, and to confirm this sensible thought I stood in the window as the twilight deepened the gloom of the already cheerless scene. The new cabins, the piles of timber, the circular stone enclosure for campfire, were very real and diverted my thoughts from the past to the cheerful future and the new life which would soon throng Leatherstocking Camp. If I attached some tragic meaning to every idle scratching on fence or wall or sidewalk, I should soon be as absurd as my adventurous young friend, Pee-wee Harris, of whom you may have heard. That is what I told myself.
By way of dealing with worth-while realities, I prepared my supper. Tom says I am utterly useless except in wielding a fountain pen. But I think I make very good applesauce and my poached eggs have a beauty of form which I dare not aspire to in the field of literary art. I need not detain you with my reveries before the blazing logs after my lonely supper. I thought of my work and studiously avoided any speculations about the past at Leatherstocking Camp. Nothing really strange or suspicious had occurred there. It was the scene of a tragic accident, that was all. If there had indeed been four persons there instead of three, what of it?
