Mr. Clarke, the gentleman chosen by Dr. Raymond to witness the strange experiment of the god Pan, was a person in whose character caution and curiosity were oddly mingled; in his sober moments he thought of the unusual and eccentric with undisguised aversion, and yet, deep in his heart, there was a wide-eyed inquisitiveness with respect to all the more recondite and esoteric elements in the nature of men. The latter tendency had prevailed when he accepted Raymond’s invitation, for though his considered judgment had always repudiated the doctor’s theories as the wildest nonsense, yet he secretly hugged a belief in fantasy, and would have rejoiced to see that belief confirmed. The horrors that he witnessed in the dreary laboratory were to a certain extent salutary; he was conscious of being involved in an affair not altogether reputable, and for many years afterwards he clung bravely to the commonplace, and rejected all occasions of occult investigation. Indeed, on some homeopathic principle, he for some time attended the seances of distinguished mediums, hoping that the clumsy tricks of these gentlemen would make him altogether disgusted with mysticism of every kind, but the remedy, though caustic, was not efficacious. Clarke knew that he still pined for the unseen, and little by little, the old passion began to reassert itself, as the face of Mary, shuddering and convulsed with an unknown terror, faded slowly from his memory. Occupied all day in pursuits both serious and lucrative, the temptation to relax in the evening was too great, especially in the winter months, when the fire cast a warm glow over his snug bachelor apartment, and a bottle of some choice claret stood ready by his elbow. His dinner digested, he would make a brief pretence of reading the evening paper, but the mere catalogue of news soon palled upon him, and Clarke would find himself casting glances of warm desire in the direction of an old Japanese bureau, which stood at a pleasant distance from the hearth. Like a boy before a jam-closet, for a few minutes he would hover indecisive, but lust always prevailed, and Clarke ended by drawing up his chair, lighting a candle, and sitting down before the bureau. Its pigeon-holes and drawers teemed with documents on the most morbid subjects, and in the well reposed a large manuscript volume, in which he had painfully entered he gems of his collection. Clarke had a fine contempt for published literature; the most ghostly story ceased to interest him if it happened to be printed; his sole pleasure was in the reading, compiling, and rearranging what he called his “Memoirs to prove the Existence of the Devil,” and engaged in this pursuit the evening seemed to fly and the night appeared too short.

On one particular evening, an ugly December night, black with fog, and raw with frost, Clarke hurried over his dinner, and scarcely deigned to observe his customary ritual of taking up the paper and laying it down again. He paced two or three times up and down the room, and opened the bureau, stood still a moment, and sat down. He leant back, absorbed in one of those dreams to which he was subject, and at length drew out his book, and opened it at the last entry. There were three or four pages densely covered with Clarke’s round, set penmanship, and at the beginning he had written in a somewhat larger hand:

Singular Narrative told me by my Friend, Dr. Phillips.
He assures me that all the facts related therein are strictly and wholly True, but refuses to give either the Surnames of the Persons Concerned, or the Place where these Extraordinary Events occurred.

Mr. Clarke began to read over the account for the tenth time, glancing now and then at the pencil notes he had made when it was told him by his friend. It was one of his humours to pride himself on a certain literary ability; he thought well of his style, and took pains in arranging the circumstances in dramatic order. He read the following story:—

The persons concerned in this statement are Helen V., who, if she is still alive, must now be a woman of twenty-three, Rachel M., since deceased, who was a year younger than the above, and Trevor W., an imbecile, aged eighteen. These persons were at the period of the story inhabitants of a village on the borders of Wales, a place of some importance in the time of the Roman occupation, but now a scattered hamlet, of not more than five hundred souls. It is situated on rising ground, about six miles from the sea, and is sheltered by a large and picturesque forest.

Some eleven years ago, Helen V. came to the village under rather peculiar circumstances. It is understood that she, being an orphan, was adopted in her infancy by a distant relative, who brought her up in his own house until she was twelve years old. Thinking, however, that it would be better for the child to have playmates of her own age, he advertised in several local papers for a good home in a comfortable farmhouse for a girl of twelve, and this advertisement was answered by Mr. R., a well-to-do farmer in the above-mentioned village. His references proving satisfactory, the gentleman sent his adopted daughter to Mr. R., with a letter, in which he stipulated that the girl should have a room to herself, and stated that her guardians need be at no trouble in the matter of education, as she was already sufficiently educated for the position in life which she would occupy. In fact, Mr. R. was given to understand that the girl be allowed to find her own occupations and to spend her time almost as she liked. Mr. R. duly met her at the nearest station, a town seven miles away from his house, and seems to have remarked nothing extraordinary about the child except that she was reticent as to her former life and her adopted father. She was, however, of a very different type from the inhabitants of the village; her skin was a pale, clear olive, and her features were strongly marked, and of a somewhat foreign character. She appears to have settled down easily enough into farmhouse life, and became a favourite with the children, who sometimes went with her on her rambles in the forest, for this was her amusement. Mr. R. states that he has known her to go out by herself directly after their early breakfast, and not return till after dusk, and that, feeling uneasy at a young girl being out alone for so many hours, he communicated with her adopted father, who replied in a brief note that Helen must do as she chose. In the winter, when the forest paths are impassable, she spent most of her time in her bedroom, where she slept alone, according to the instructions of her relative. It was on one of these expeditions to the forest that the first of the singular incidents with which this girl is connected occurred, the date being about a year after her arrival at the village. The preceding winter had been remarkably severe, the snow drifting to a great depth, and the frost continuing for an unexampled period, and the summer following was as noteworthy for its extreme heat. On one of the very hottest days in this summer, Helen V. left the farmhouse for one of her long rambles in the forest, taking with her, as usual, some bread and meat for lunch. She was seen by some men in the fields making for the old Roman Road, a green causeway which traverses the highest part of the wood, and they were astonished to observe that the girl had taken off her hat, though the heat of the sun was already tropical. As it happened, a labourer, Joseph W. by name, was working in the forest near the Roman Road, and at twelve o’clock his little son, Trevor, brought the man his dinner of bread and cheese. After the meal, the boy, who was about seven years old at the time, left his father at work, and, as he said, went to look for flowers in the wood, and the man, who could hear him shouting with delight at his discoverie............
