shown me in London, and my heart began to beat with the thought that I was presently to know something. I took the seal, and holding it up to the light checked off the grotesque dagger-shaped characters one by one.
"I make sixty-two," I said at last.
"Sixty-two? Nonsense; it's impossible. Ah, I see what you have done, you have counted that and that," and he pointed to two marks which I had certainly taken as letters with the rest.
"Yes, yes," Professor Gregg went on; "but those are obvious scratches, done accidentally; I saw that at once. Yes, then that's quite right. Thank you very much, Miss Lally."
I was going away, rather disappointed at my having been called in merely to count a number of marks on the black seal, when suddenly there flashed into my mind what I had read in the morning.
"But, Professor Gregg, I cried, breathless, the seal, the seal. Why, it is the stone Hexecontalithos that Solinus writes of; it is Ixaxar."
"Yes," he said, "I suppose it is. Or it maybe a mere coincidence. It never does to be too sure, you know, in these matters. Coincidence killed the professor."
I went away puzzled by what I had heard, and as much as ever at a loss to find the ruling clew in this maze of strange evidence. For three days the bad weather lasted, changing from driving rain to a dense mist, fine and dripping, and we seemed to be shut up in a white cloud that veiled all the world away from us. All the while Professor Gregg was darkling in his room, unwilling, it appeared, to dispense confidences or talk of any kind, and I heard him walking to and fro with a quick, impatient step, as if he were in some way wearied of inaction. The fourth morning was fine, and at breakfast the professor said briskly:—
"We want some extra help about the house; a boy of fifteen or sixteen, you know. There are a lot of little odd jobs that take up the maids' time, which a boy could do much better."
"The girls have not complained to me in any way," I replied. "Indeed, Anne said there was much less work than in London, owing to there being so little dust."
"Ah, yes, they are very good girls. But I think we shall do much better with a boy. In fact, that is what has been bothering me for the last two days."
"Bothering you?" I said in astonishment, for as a matter of fact the professor never took the slightest interest in the affairs of the house.
"Yes," he said, "the weather, you know. I really couldn't go out in that Scotch mist; I don't know the country very well, and I should have lost my way. But I am going to get the boy this morning."
"But how do you know there is such a boy as you want anywhere about?"
"Oh, I have no doubt as to that. I may have to walk a mile or two at the most, but I am sure to find just the boy I require."
I thought the professor was poking, but though his tone was airy enough there was something grim and set about his features that puzzled me. He got his stick, and stood at the door looking meditatively before him, and as I passed through the hall he called to me.
"By the way, Miss Lally, there was one thing I wanted to say to you. I daresay you may have heard that some of these country lads are not over bright; idiotic would be a harsh word to use, and they are usually called 'naturals,' or something of the kind, I hope you won't mind if the boy I am after should turn out not too keen-witted; he will be perfectly harmless, of course, and blacking boots doesn't need much mental effort."
With that he was gone, striding up the road that led to the wood; and I remained stupefied, and then for the first time my astonishment was mingled with a sudden note of terror, arising I knew not whence, and all unexplained even to myself, and yet I felt about my heart for an instant something of the chill of death, and that shapeless, formless dread of the unknown that is worse than death itself. I tried to find courage in the sweet air that blew up from the sea, and in the sunlight after rain, but the mystic woods seemed to darken around me; and the vision of the river coiling between the reeds, and the silver gray of the ancient bridge, fashioned in my mind symbols of vague dread, as the mind of a child fashions terror from things harmless and familiar.
Two hours later Professor Gregg returned. I met him as he came down the road, and asked quietly if he had been able to find a boy.
"Oh, yes," he answered; "I found one easily enough. His name is Jervase Cradock, and I expect he will make himself very useful. His father has been dead for many years, and the mother, whom I saw, seemed very glad at the prospect of a few shillings extra coming in on Saturday nights. As I expected, he is not too sharp, has fits at times, the mother said; but as he will not be trusted with the china, that doesn't much matter, does it? And he is not in any way dangerous, you know, merely a little weak."
"When is he coming?"
"To-morrow morning at eight o'clock. Anne will show him what he has to do, and how to do it. At first he will go home every night, but perhaps it may ultimately turn out more convenient for him to sleep here, and only go home for Sundays."
I found nothing to say to all this. Professor Gregg spoke in a quiet tone of matter-of-fact, as indeed was warranted by the circumstance; and yet I could not quell my sensation of astonishment at the whole affair. I knew that in reality no assistance was wanted in the housework, and the professor's prediction that the boy he was to engage might prove a little "simple," followed by so exact a fulfilment, struck me as bizarre in the extreme. The next morning I heard from, the housemaid that the boy Cradock had come at eight, and that she had been trying to make him useful. "He doesn't seem quite all there, I don't think, miss," was her comment; and later in the day I saw him helping the old man who worked in the garden. He was a youth of about fourteen, with black hair and black eyes, and an olive skin, and I saw at once from the curious vacancy of his expression that he was mentally weak. He touched his forehead awkwardly as I went by, and I heard him answering the gardener in a queer, harsh voice that caught my attention; it gave me the impression of some one speaking deep below under the earth, and there was a strange sibilance, like the hissing of the phonograph as the pointer travels over the cylinder. I heard that he seemed anxious to do what he could, and was quite docile and obedient, and Morgan the gardener, who knew his mother, assured me he was perfectly harmless. "He's always been a bit queer," he said, "and no wonder, after what his mother went through before he was born. I did know his father, Thomas Cradock, well, and a very fine workman he was too, indeed. He got something wrong with his lungs owing to working in the wet woods, and never got over it, and went off quite sudden like. And they do say as how Mrs. Cradock was quite off her head; anyhow, she was found by Mr. Hillyer, Ty Coch, all crouched up on the Gray Hills, over there, crying and weeping like a lost soul. And Jervase he was born about eight months afterwards, and as I was saying, he was a bit queer always; and they do say when he could scarcely walk he would frighten the other children into fits with the noises he would make."
A word in the story had stirred up some remembrance within me, and vaguely curious, I asked the old man where the Gray Hills were.
"Up there," he said, with the same gesture he had used before; "you go past the Fox and Hounds, and through the forest, by the old ruins. It's a good five mile from here, and a strange sort of a place. The poorest soil between this and Monmouth, they do say, though it's good feed for sheep. Yes, it was a sad thing for poor Mrs. Cradock."
The old man turned to his work, and I strolled on down the path between the espaliers, gnarled and gouty with age, thinking of the story I had heard, and groping for the point in it that had some key to my memory. In an instant it came before me; I had seen the phrase "Gray Hills" on the slip of yellowed paper that Professor Gregg had taken from the drawer in his cabinet. Again I was seized with pangs of mingled curiosity and fear; I remembered the strange characters copied from the
