Next moment I realized that I was at that place where Leithcourt so persistently kept his disappointed tryst, having approached it from within the wood.
The sound alarmed me, and yet it was neither an explosion of fire-arms nor a startling cry for help.
One word reached me in the darkness-one single word of bitter and withering reproach.
Heedless of the risk I ran and the peril to which I exposed myself, I dashed forward with a resolve to penetrate the mystery, until I came to the gap in the rough stone wall where Leithcourt's habit was to halt each day at sundown.
There, in the falling darkness, the sight that met my eyes at the spot held me rigid, appalled, stupefied.
In that instant I realized the truth-a truth that was surely the strangest ever revealed to any man.
CHAPTER V CONTAINS CERTAIN CONFIDENCES
As I dashed forward to the gap in the boundary wall of the wood, I nearly stumbled over a form lying across the narrow path.
So dark was it beneath the trees that at first I could not plainly make out what it was until I bent and my hands touched the garments of a woman. Her hat had fallen off, for I felt it beneath my feet, while the cloak was a thick woolen one.
Was she dead, I wondered? That cry-that single word of reproach-sounded in my ears, and it seemed plain that she had been struck down ruthlessly after an exchange of angry words.
I felt in my pocket for my vestas, but unfortunately my box was empty. Yet just at that moment my strained ears caught a sound-the sound of someone moving stealthily among the fallen leaves. Seizing my gun, I demanded who was there.
There was, however, no response. The instant I spoke the movement ceased.
As far as I could judge, the person in concealment was within the wood about ten yards from me, separated by an impenetrable thicket. As, however, I stood out against the sky, my silhouette was, I knew, a well-defined mark for anyone with fire-arms.
It seemed evident that a tragedy had occurred, and that the victim at my feet was a woman. But whom?
Of a sudden, while I stood hesitating, blaming myself for being without matches, I heard the movement repeated. Someone was quickly receding-escaping from the spot. I listened again. The sound was not of the rustling of leaves or the crackling of dried sticks, but the low thuds of a man's feet racing over softer ground. He had scaled the rough stone dyke and was out in the turnip-field adjacent.
I sprang through the gap, straining my eyes into the gloom, and as I did so could just distinguish a dark figure receding quickly beneath the wall of the wood.
In an instant I dashed after it. But the agility of whoever the fugitive was, man or woman, was marvelous. I considered myself a fairly good runner, but racing across those rough turnips and heavy, newly-plowed land in the darkness and carrying my gun soon caused me to pant and blow. Yet the figure I was pursuing was so fleet of foot and so nimble in climbing the high rough walls that from the very first I was outrun.
Down the steep hill to the Scarwater I followed the fugitive, crossing the old footbridge near Penpont, and then up a wild winding glen towards the Cairnsmore of Deugh. For a couple of miles or more I was close behind, until, at a turn in the dark wooded glen where it branched in two directions, I lost all trace of the person who flew from me. Whoever it was they had very cleverly gone into hiding in the undergrowth of one or other of the two glens-which I could not decide.
I stood out of breath, the perspiration pouring from me, undecided how to act.
Was it Leithcourt himself whom I had surprised?
That idea somehow became impressed upon me and I suddenly resolved to go boldly across to Rannoch and ascertain for myself. Therefore, with the excuse that I was belated on my walk home, I turned back down the glen, and half an hour afterward entered the great well-lighted hall of the castle where the guests, ready dressed, were assembling prior to dinner.
I was welcomed warmly, as I was always by the men of the party, who seeing my muddy plight at once offered me a glass of the sportsman's drink in Scotland, and while I was adding soda to it Leithcourt himself joined his guests, ready dressed in his dinner jacket, having just descended from his room.
"Hulloa, Gregg!" he exclaimed heartily, holding out his hand. "Had a long day of it, evidently. Good sport with Carmichael-eh?"
"Very fair," I said. "I remained longer with him than I ought to have done, and have got belated on my way home, so looked in for a refresher."
"Quite right," he laughed merrily. "You're always welcome, you know. I'd have been annoyed if I knew you had passed without coming in."
And Muriel, a pretty figure in a low-cut gown of turquoise chiffon, standing behind her father, smiled secretly at me. I smiled at her in return, but it was a strange smile, I fear, for with the knowledge of that additional mystery within me-the mystery of the woman lying unconscious or perhaps dead, up in the wood-held me stupefied.
I had suspected Leithcourt because of his constant trysts at that spot, but I had at least proved that my suspicions were entirely without foundation. He could not have got home and dressed in the time, for I had taken the nearest route to the castle while the fugitive would be compelled to make a wide detour.
I only remained a few minutes, then went forth into the darkness again, utterly undecided how to act. My first impulse was to return to the woman's aid, for she might not be dead after all.
And yet when I recollected that hoarse cry that rang out in the darkness, I knew too well that she had been struck fatally. It was this latter conviction that prevented me from turning back to the wood. You will perhaps blame me, but the fact is I feared that if I went there suspicion might fall upon me, now that the real culprit had so ingeniously escaped.
If the victim were dead, what aid could I render? A knife had, I believed, been used, for my foot caught against it when I had started off after the fugitive. The only doubt in my own mind was whether the unfortunate woman was actually dead, for if she were not then my disinclination to return to the scene of the tragedy was culpable.
Whether or not I acted rightly in remaining away from the place, I leave it to you to judge in the light of the amazing truth which afterwards transpired.
I decided to walk straight back to my uncle's, and dinner was over before I had had my tub and dressed. I therefore ate my meal alone, Davis, the grave old butler, serving me with that stateliness which always amused me. I usually chatted with him when others were not present, but that night I remained silent, my mind full of that strange and startling affair of which I alone held secret knowledge.
Next day the body would surely be found; then the whole countryside would be filled with horror and surprise. Was it possible that Leithcourt, that calm, well-groomed, distinguished-looking man, held any knowledge of the ghastly truth? No. His manner as he stood in the hall chatting gayly with me was surely not that of a man with a guilty secret. I became firmly convinced that although the tragedy affected him very closely, and that it had occurred at the spot which he had each day visited for some mysterious purpose, yet up to the present he was in ignorance of what had transpired.
But who was the woman? Was she young or old?
A thousand times I regretted bitterly that I had no matches with me so that I might examine her features.
One sudden thought that struck me as I sat there at table caused me to lay down my fork and pause in breathless bewilderment. Was the victim that sweet-faced young girl whose photograph had been so ruthlessly cast from its frame and destroyed? The theory was a weird one, but was it the truth?
I longed for the coming of the dawn when the Rannoch keepers would most certainly discover her. Then at least I should know the truth, for I might go and see the body out of curiosity without arousing any suspicion.
