Mr. Vaughan had spoken earnestly, and bent forward in his chair and glanced at Dyson with something of entreaty.
“My dear Vaughan,” said the other, after a pause, “what’s the use of this? It is much too late to take that tone; we have gone too deep. Besides you know as well as I that there is no delusion in the case; I wish there were with all my heart. No, in justice to myself I must tell you the whole story, so far as I know it.”
“Very good,” said Vaughan with a sigh, “if you must, you must.”
“Then,” said Dyson, “we will begin with the end if you please. I found this brooch you have just identified in the place we have called the Bowl. There was a heap of grey ashes, as if a fire had been burning, indeed, the embers were still hot, and this brooch was lying on the ground, just outside the range of the flame. It must have dropped accidentally from the dress of the person who was wearing it. No, don’t interrupt me; we can pass now to the beginning, as we have had the end. Let us go back to that day you came to see me in my rooms in London. So far as I can remember, soon after you came in you mentioned, in a somewhat casual manner, that an unfortunate and mysterious incident had occurred in your part of the country; a girl named Annie Trevor had gone to see a relative, and had disappeared. I confess freely that what you said did not greatly interest me; there are so many reasons which may make it extremely convenient for a man and more especially a woman to vanish from the circle of their relations and friends. I suppose, if we were to consult the police, one would find that in London somebody disappears mysteriously every other week, and the officers would, no doubt, shrug their shoulders, and tell you that by the law of averages it could not be otherwise. So I was very culpably careless to your story, and besides, here is another reason for my lack of interest; your tale was inexplicable. You could only suggest a blackguard sailor on the tramp, but I discarded the explanation immediately.
“For many reasons, but chiefly because the occasional criminal, the amateur in brutal crime, is always found out, especially if he selects the country as the scene of his operations. You will remember the case of that Garcia you mentioned; he strolled into a railway station the day after the murder, his trousers covered with blood, and the works of the Dutch clock, his loot, tied in a neat parcel. So rejecting this, your only suggestion, the whole tale became, as I say, inexplicable, and, therefore, profoundly uninteresting. Yes, therefore, it is a perfectly valid conclusion. Do you ever trouble your head about problems which you know to be insoluble? Did you ever bestow much thought on the old puzzle of Achilles and the tortoise? Of course not, because you knew it was a hopeless quest, and so when you told me the story of a country girl who had disappeared I simply placed the whole thing down in the category of the insoluble, and thought no more about the matter. I was mistaken, so it has turned out; but if you remember, you immediately passed on to an affair which interested you more intensely, because personally, I need not go over the very singular narrative of the flint signs, at first I thought it all trivial, probably some children’s game, and if not that a hoax of some sort; but your showing me the arrow-head awoke my acute interest. Here, I saw, there was something widely removed from the commonplace, and matter of real curiosity; and as soon as I came here I set to work to find the solution, repeating to myself again and again the signs you had described. First came the sign we have agreed to call the Army; a number of serried lines of flints, all pointing in the same way. Then the lines, like the spokes of a wheel, all converging towards the figure of a Bowl, then the triangle or Pyramid, and last of all the Half moon. I confess that I exhausted conjecture in my efforts to unveil this mystery, and as you will understand it was a duplex or rather triplex problem. For I had not merely to ask myself: what do these figures mean? but also, who can possibly be responsible for the designing of them? And again, who can possibly possess such valuable things, and knowing their value thus throw them down by the wayside? This line of thought led me to suppose that the person or persons in question did not know the value of unique flint arrow-heads, and yet this did not lead me far, for a well-educated man might easily be ignorant on such a subject. Then came the complication of the eye on the wall, and you remember that we could not avoid the conclusion that in the two cases the same agency was at work. The peculiar position of these eyes on the wall made me inquire if there was such a thing as a dwarf anywhere in the neighbourhood, but I found that there was not, and I knew that the children who pass by every day had nothing to do with the matter. Yet I felt convinced that whoever drew the eyes must be from three and a half to four feet high, since, as I pointed out at the time, anyone who draws on a perpendicular surface chooses by instinct a spot about level with his face. Then again, there was the question of the peculiar shape of the eyes; that marked Mongolian character of which the English countryman could have no conception, and for a final cause of confusion the obvious fact that the designer or designers must be able practically to see in the dark. As you remarked, a man who has been confined for many years in an extremely dark cell or dungeon might acquire that power; but since the days of Edmond Dantés, where would such a prison be found in Europe? A sailor, who had been immured for a considerable period in some horrible Chinese oubliette, seemed the individual I was in search of, and though it looked improbable, it was not absolutely impossible that a sailor or, let us say, a man employed on shipboard, should be a dwarf. But how to account for my imaginary sailor being in possesion of prehistoric arrow-heads? And the possession granted, what was the meaning and object of these mysterious signs of flint, and the almond-shaped eyes? Your theory of a contemplated burglary I saw, nearly from the first, to be quite untenable, and I confess I was utterly at a loss for a working hypothesis. It was a mere accident which put me on the track; we passed poor old Trevor, and your mention of his name and of the disappearance of his daughter, recalled the story which I had forgotten, or which remained unheeded. Here, then, I said to myself, is another problem, uninteresting, it is true, by itself; but what if it prove to be in relation with all these enigmas which torture me? I shut myself in my room, and endeavoured to dismiss all prejudice from my mind, and I went over everything de novo, assuming for theory’s sake that the disappearance of Annie Trevor had some connection with the flint signs and the eyes on the wall. This assumption did not lead me very far, and I was on the point of giving the whole problem up in despair, when a possible significance of the Bowl struck me. As you know there is a ‘Devil’s Punch-bowl’ in Surrey, and I saw that the symbol might refer to some feature in the country. Putting the two extremes together, I determined to look for the Bowl near the path which the lost girl had taken, and you know how I found it. I interpreted the sign by what I knew, and read the first, the Army, thus:
‘there is to be a gathering or assembly at the Bowl in a fortnight (that is the Half moon) to see the Pyramid, or to build the Pyramid.’
The eyes, drawn one by one, day by day, evidently checked off the days, and I knew that there would be fourteen and no more. Thus far the way seemed pretty plain; I would not trouble myself to inquire as to the nature of the assembly, or as to who was to assemble in the loneliest and most dreaded place among these lonely hills. In Ireland or China or the West of America the question would have been easily answered; a muster of the disaffected, the meeting of a secret society; vigilantes summoned to report: the thing would be simplicity itself; but in this quiet corner of England, inhabited by quiet folk, no such suppositions were possible for a moment. But I knew that I should have an opportunity of seeing and watching the assembly, and I did not care to perplex myself with hopeless research; and in place of reasoning a wild fancy entered into judgment: I remembered what people had said about Annie Trevor’s disappearance, that she had been ‘taken by the fairies.’ I tell you, Vaughan, I am a sane man as you are, my brain is not, I trust, mere vacant space to let to any wild improbability, and I tried my best to thrust the fantasy away. And the hint came of the old name of fairies, ‘the little people,’ and the very probable belief that they represent a tradition of the prehistoric Turanian inhabitants of the country, who were cave dwellers: and then I realized with a shock that I was looking for a being under four feet in height, accustomed to live in darkness, possessing stone instruments, and familiar with the Mongolian cast of features! I say this, Vaughan, that I should be ashamed to hint at such visionary stuff to you, if it were not for that which you saw with your very eyes last night, and I say that I might doubt the evidence of my senses, if they were not confirmed by yours. But you and I cannot look each other in the
