"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.

I tried to play my usual game of billiards with my uncle, but my hand was so unsteady that the old gentleman began to chaff me.

"It's the gun, I suppose," I remarked. "I've been carrying it all day, and am tired out. I walked all the way home from Crossburn."

"The Carmichaels are very thick with the Leithcourts, I hear," my uncle remarked. "Strange they didn't ask Leithcourt to their shoot."

"They did, but he'd got another engagement—over at Kenmure Castle, I think."

I retired to my room that night full of fevered apprehension. Had I acted rightly in not returning to that lonely spot on the brow of the hill? Had I done as a man should do in keeping the tragic secret to myself?

I opened my window and gazed away across the dark Nithsdale, where, in the distant gloom, the black line of wood loomed up against the stormy sky. The stars were no longer shining and the rain clouds had gathered. I stood with my face turned to the dark indistinct spot that held the secret, lost in wonderment.

At last I closed the window and turned in, but no sleep came to my eyes, so full was my mind of the startling events of those past few months and of that gruesome discovery I had made.

Had the fugitive actually recognized me? Probably my voice when I had called out had betrayed me. Hour after hour I lay puzzling, trying to arrive at some solution of that intricate problem which now presented itself. Muriel could tell me what I wished to know. Of that I was certain. Yet she dared not speak. Some inexpressible terror held her dumb—she was affianced to the man Martin Woodroffe.

Again I rose, lit the gas, and tried to read a novel. But I could not concentrate my thoughts, which were ever wandering to that strange mystery of the wood. At six I shaved, descended, and went out with the dogs for a short walk; but on returning I heard of nothing unusual, and was compelled to remain inactive until near mid-day.

I was crossing the stable-yard where I had gone to order the carriage for my aunt, when an English groom, suddenly emerging from the harness-room, touched his cap, saying—

"Have you 'eard, sir, of the awful affair up yonder?"

"Of what?" I asked quickly.

"Well, sir, there seems to have been a murder last night up in Rannoch Wood," said the man quickly. "Holden, the gardener, has just come back from that village and says that Mr. Leithcourt's under-gamekeeper as he was going home at five this morning came upon a dead body."

"A dead body!" I exclaimed, feigning great surprise.

"Yes, sir—a youngish man. He'd been stabbed to the heart."

"A man!"

"Yes, sir—so Holden says."

"Call Holden. I'd like to know all he's heard," I said. And presently, when the gardener emerged from the grape-house, I sought of him all the particulars he had gathered.

"I don't know very much, sir," was the man's reply. "I went into the inn for a glass of beer at eleven, as I always do, and heard them talking about it. A young man was murdered last night up in Rannoch Wood. The gamekeeper thought at first there'd been a fight among poachers, but from the dead man's clothes they say he isn't a poacher at all, but a stranger in this district."

"The body was that of a man, then?" I asked, trying to conceal my utter bewilderment.

"Yes—about thirty, they say. The police have taken him to the mortuary at Dumfries, and the detectives are up there now looking at the spot, they say."

A man! And yet the body I found was that of a woman—that I could swear.

After lunch I took the dog-cart and drove alone into Dumfries.

When I inquired of the police-constable on duty at the town mortuary to be allowed to view the body of the murdered man, he regarded me, I thought, with considerable suspicion. My request was an unusual one. Nevertheless, he took me up a narrow alley, unlocked a door, and I found myself in the cold, gloomy chamber of death. From a small dingy window above the light fell upon an object lying upon a large slab of gray stone and covered with a soiled sheet.

The sight was ghastly and gruesome; the body lay there awaiting the official inquiry into the cause of death. The silence of the tomb was unbroken, save for the heavy tread of the policeman, who having removed his helmet in the presence of the dead, lifted the end of the sheet, revealing to me a white, hard-set face, with closed eyes and dropped jaw.

I started back as my eyes fell upon the dead countenance. I was entirely unprepared for such a revelation. The truth staggered me.

The victim was the man who had acted as my friend—the Italian waiter, Olinto.

I advanced and peered into the thin inanimate features, scarce able to realize the actual fact. But my eyes had not deceived me. Though death distorts the facial expression of every man, I had no difficulty in identifying him.

"You recognize him, sir?" remarked the officer. "Who is he? Our people are very anxious to know, for up to the present moment they haven't succeeded in establishing his identity."

I bit my lips. I had been an arrant fool to betray myself before that man. Yet having done so, I saw that any attempt to conceal my knowledge must of necessity reflect upon me.

"I will see your inspector," I answered with as much calmness as I could muster. "Where has the poor fellow been wounded?"

"Through the heart," responded the constable, as turning the sheet further down he showed me the small knife wound which had penetrated the victim's jacket and vest full in the chest.

"This is the weapon," he added, taking from a shelf close by a long, thin poignard with an ivory handle, which he handed to me.

In an instant I recognized what it was, and how deadly. It was an old Florentine misericordia, a long thin, triangular blade, a quarter of an inch wide at its greatest width, tapering to a needle-point, with a hilt of yellow ivory, the most deadly and fatal of all the daggers and poignards of the Middle Ages. The blade being sharp on three angles produced a wound that caused internal hemorrhage and which never healed—hence the name given to it by the Florentines.

It was still blood-stained, but as I took the deadly thing in my hand I saw that its blade was beautifully damascened, a most elegant specimen of a medieval arm. Yet surely none but an Italian would use such a weapon, or would aim so truly as to penetrate the heart.

And yet the person struck down was a woman, and not a man!
