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 limestone rock, and then again their identity with the inscription on the age-old seal, and the fantastic fables of the Latin geographer. I saw beyond doubt that, unless coincidence had set all the scene and disposed all these bizarre events with curious art, I was to be a spectator of things far removed from the usual and customary traffic and jostle of life. Professor Gregg I noted day by day. He was hot on his trail, growing lean with eagerness; and in the evenings, when the sun was swimming on the verge of the mountain, he would pace the terrace to and fro with his eyes on the ground, while the mist grew white in the valley, and the stillness of the evening brought far voices near, and the blue smoke rose a straight column from the diamond-shaped chimney of the gray farmhouse, just as I had seen it on the first morning. I have told you I was of sceptical habit; but though I understood little or nothing, I began to dread, vainly proposing to myself the iterated dogmas of science that all life is material, and that in the system of things there is no undiscovered land even beyond the remotest stars, where the supernatural can find a footing. Yet there struck in on this the thought that matter is as really awful and unknown as spirit, that science itself but dallies on the threshold, scarcely gaining more than a glimpse of the wonders of the inner place.
There is one day that stands up from amidst the others as a grim red beacon, betokening evil to come. I was sitting on a bench in the garden, watching the boy Cradock weeding, when I was suddenly alarmed by a harsh and choking sound, like the cry of a wild beast in anguish, and I was unspeakably shocked to see the unfortunate lad standing in full view before me, his whole body quivering and shaking at short intervals as though shocks of electricity were passing through him, and his teeth grinding, and foam gathering on his lips, and his face all swollen and blackened to a hideous mask of humanity. I shrieked with terror, and Professor Gregg came running; and as I pointed to Cradock, the boy with one convulsive shudder fell face forward, and lay on the wet earth, his body writhing like a wounded blind-worm, and an inconceivable babble of sounds bursting and rattling and hissing from his lips; he seemed to pour forth an infamous jargon, with words, or what seemed words, that might have belonged to a tongue dead since untold ages, and buried deep beneath Nilotic mud, or in the inmost recesses of the Mexican forest. For a moment the thought passed through my mind, as my ears were still revolted with that infernal clamor, "Surely this is the very speech of hell," and then I cried out again and again, and ran away shuddering to my inmost soul. I had seen Professor Gregg's face as he stooped over the wretched boy and raised him, and I was appalled by the glow of exultation that shone on every lineament and feature. As I sat in my room with drawn blinds, and my eyes hidden in my hands, I heard heavy steps beneath, and I was told afterwards that Professor Gregg had carried Cradock to his study, and had locked the door. I heard voices murmur indistinctly, and I trembled to think of what might be passing within a few feet of where I sat; I longed to escape to the woods and sunshine, and yet I dreaded the sights that might confront me on the way. And at last, as I held the handle of the door nervously, I heard Professor Gregg's voice calling to me with a cheerful ring: "It's all right now, Miss Lally," he said. "The poor fellow has got over it, and I have been arranging for him to sleep here after to-morrow. Perhaps I may be able to do something for him."
"Yes," he said later, "it was a very painful sight, and I don't wonder you were alarmed. We may hope that good food will build him up a little, but I am afraid he will never be really cured;" and he affected the dismal and conventional air with which one speaks of hopeless illness, and yet beneath it I detected the delight that leapt up rampant within him, and fought and struggled to find utterance. It was as if one glanced down on the even surface of the sea, clear and immobile, and saw beneath raging depths, and a storm of contending billows. It was indeed to me a torturing and offensive problem that this man, who had so bounteously rescued me from the sharpness of death, and showed himself in all the relations of life full of benevolence and pity and kindly forethought, should so manifestly be for once on the side of the demons, and take a ghastly pleasure in the torments of an afflicted fellow-creature. Apart, I struggled with the horned difficulty, and strove to find the solution, but without the hint of a clue; beset by mystery and contradiction, I saw nothing that might help me, and began to wonder whether, after all, I had not escaped from the white mist of the suburb at too dear a rate. I hinted something of my thought to the professor; I said enough to let him know that I was in the most acute perplexity, but the moment after regretted what I had done, when I saw his face contort with a spasm of pain.
"My dear Miss Lally," he said, "you surely do not wish to leave us? No, no, you would not do it. You do not know how I rely on you; how confidently I go forward, assured that you are here to watch over my children. You, Miss Lally, are my rear-guard; for, let me tell you, that the business in which I am engaged is not wholly devoid of peril. You have not forgotten what I said the first morning here; my lips are shut by an old and firm resolve, till they can open to utter no ingenious hypothesis or vague surmise but irrefragable fact, as certain as a demonstration in mathematics. Think over it, Miss Lally, not for a moment would I endeavor to keep you here against your own instincts, and yet I tell you frankly that I am persuaded that it is here, here amidst the woods, that your duty lies."
I was touched by the eloquence of his tone, and by the remembrance that the man, after all, had been my salvation, and I gave him my hand on a promise to serve him loyally and without question. A few days later the rector of our church, a little church, gray and severe and quaint, that hovered on the very banks of the river and watched the tides swim and return, came to see us, and Professor Gregg easily persuaded him to stay and share our dinner. Mr. Meyrick was a member of an antique family of squires, whose old manor house stood amongst the hills some seven miles away, and thus rooted in the soil, the rector was a living store of all the old fading customs and lore of the country. His manner, genial with a deal of retired oddity, won on Professor Gregg; and towards the cheese, when a curious Burgundy had begun its incantations, the two men glowed like the wine, and talked of philology with the enthusiasm of a burgess over the peerage. The parson was expounding the pronunciation of the Welsh ll, and producing sounds like the gurgle of his native brooks, when Professor Gregg struck in.
"By the way," he said, "that was a very odd word I met with the other day. You know my boy, poor Jervase Cradock. Well, he has got the bad habit of talking to himself, and the day before yesterday I was walking in the garden here and heard him; he was evidently quite unconscious of my presence. A lot of what he said I couldn't make out, but one word, struck me distinctly. It was such an odd sound; half-sibilant, half-guttural, and as quaint as those double ll's you have been demonstrating. I do not know whether I can give you an idea of the sound. "Ishakshar" is perhaps as near as I can get; but the k ought to be a Greek chi or a Spanish j. Now what does it mean in Welsh?"
"In Welsh?" said the parson. "There is no such word in Welsh, nor any word remotely resembling
