The Parasite

The Parasite
Arthur Conan Doyle

The Parasite was an 1894 novelette about Austin Gilroy who studied physiology and knows a professor who studies the occult. The young man is introduced to a middle-aged woman known as Miss Penclosa, who has a crippled leg and psychic powers. Gilroy begins to visit this psychic and look at the physical part of her powers. Miss Penclosa falls in love with the unfortunate Gilroy. When she uses her powers on him, Gilroy is angered and rejects her. She in turn begins to play tricks on Gilroy. The cruel tricks end with him in his fiance Agatha's room carrying a small bottle of poison. What will he find when he rushes back to Miss Penclosa's house?

The Parasite, a story

by Sir Arthur Conan Doyle

I

March 24. The spring is fairly with us now. Outside my laboratory window the great chestnut-tree is all covered with the big, glutinous, gummy buds, some of which have already begun to break into little green shuttlecocks. As you walk down the lanes you are conscious of the rich, silent forces of nature working all around you. The wet earth smells fruitful and luscious. Green shoots are peeping out everywhere. The twigs are stiff with their sap; and the moist, heavy English air is laden with a faintly resinous perfume. Buds in the hedges, lambs beneath them – everywhere the work of reproduction going forward!

I can see it without, and I can feel it within. We also have our spring when the little arterioles dilate, the lymph flows in a brisker stream, the glands work harder, winnowing and straining. Every year nature readjusts the whole machine. I can feel the ferment in my blood at this very moment, and as the cool sunshine pours through my window I could dance about in it like a gnat. So I should, only that Charles Sadler would rush upstairs to know what was the matter. Besides, I must remember that I am Professor Gilroy. An old professor may afford to be natural, but when fortune has given one of the first chairs in the university to a man of four-and-thirty he must try and act the part consistently.

What a fellow Wilson is! If I could only throw the same enthusiasm into physiology that he does into psychology, I should become a Claude Bernard at the least. His whole life and soul and energy work to one end. He drops to sleep collating his results of the past day, and he wakes to plan his researches for the coming one. And yet, outside the narrow circle who follow his proceedings, he gets so little credit for it. Physiology is a recognized science. If I add even a brick to the edifice, every one sees and applauds it. But Wilson is trying to dig the foundations for a science of the future. His work is underground and does not show. Yet he goes on uncomplainingly, corresponding with a hundred semi-maniacs in the hope of finding one reliable witness, sifting a hundred lies on the chance of gaining one little speck of truth, collating old books, devouring new ones, experimenting, lecturing, trying to light up in others the fiery interest which is consuming him. I am filled with wonder and admiration when I think of him, and yet, when he asks me to associate myself with his researches, I am compelled to tell him that, in their present state, they offer little attraction to a man who is devoted to exact science. If he could show me something positive and objective, I might then be tempted to approach the question from its physiological side. So long as half his subjects are tainted with charlatanerie and the other half with hysteria we physiologists must content ourselves with the body and leave the mind to our descendants.

No doubt I am a materialist. Agatha says that I am a rank one. I tell her that is an excellent reason for shortening our engagement, since I am in such urgent need of her spirituality. And yet I may claim to be a curious example of the effect of education upon temperament, for by nature I am, unless I deceive myself, a highly psychic man. I was a nervous, sensitive boy, a dreamer, a somnambulist, full of impressions and intuitions. My black hair, my dark eyes, my thin, olive face, my tapering fingers, are all characteristic of my real temperament, and cause experts like Wilson to claim me as their own. But my brain is soaked with exact knowledge. I have trained myself to deal only with fact and with proof. Surmise and fancy have no place in my scheme of thought. Show me what I can see with my microscope, cut with my scalpel, weigh in my balance, and I will devote a lifetime to its investigation. But when you ask me to study feelings, impressions, suggestions, you ask me to do what is distasteful and even demoralizing. A departure from pure reason affects me like an evil smell or a musical discord.

Which is a very sufficient reason why I am a little loath to go to Professor Wilson's tonight. Still I feel that I could hardly get out of the invitation without positive rudeness; and, now that Mrs. Marden and Agatha are going, of course I would not if I could. But I had rather meet them anywhere else. I know that Wilson would draw me into this nebulous semi-science of his if he could. In his enthusiasm he is perfectly impervious to hints or remonstrances. Nothing short of a positive quarrel will make him realize my aversion to the whole business. I have no doubt that he has some new mesmerist or clairvoyant or medium or trickster of some sort whom he is going to exhibit to us, for even his entertainments bear upon his hobby. Well, it will be a treat for Agatha, at any rate. She is interested in it, as woman usually is in whatever is vague and mystical and indefinite.

10.50 P. M. This diary-keeping of mine is, I fancy, the outcome of that scientific habit of mind about which I wrote this morning. I like to register impressions while they are fresh. Once a day at least I endeavor to define my own mental position. It is a useful piece of self-analysis, and has, I fancy, a steadying effect upon the character. Frankly, I must confess that my own needs what stiffening I can give it. I fear that, after all, much of my neurotic temperament survives, and that I am far from that cool, calm precision which characterizes Murdoch or Pratt– Haldane. Otherwise, why should the tomfoolery which I have witnessed this evening have set my nerves thrilling so that even now I am all unstrung? My only comfort is that neither Wilson nor Miss Penclosa nor even Agatha could have possibly known my weakness.

And what in the world was there to excite me? Nothing, or so little that it will seem ludicrous when I set it down.

The Mardens got to Wilson's before me. In fact, I was one of the last to arrive and found the room crowded. I had hardly time to say a word to Mrs. Marden and to Agatha, who was looking charming in white and pink, with glittering wheat-ears in her hair, when Wilson came twitching at my sleeve.

"You want something positive, Gilroy," said he, drawing me apart into a corner. "My dear fellow, I have a phenomenon – a phenomenon!"

I should have been more impressed had I not heard the same before. His sanguine spirit turns every fire-fly into a star.

"No possible question about the bona fides this time," said he, in answer, perhaps, to some little gleam of amusement in my eyes. "My wife has known her for many years. They both come from Trinidad, you know. Miss Penclosa has only been in England a month or two, and knows no one outside the university circle, but I assure you that the things she has told us suffice in themselves to establish clairvoyance upon an absolutely scientific basis. There is nothing like her, amateur or professional. Come and be introduced!"

I like none of these mystery-mongers, but the amateur least of all. With the paid performer you may pounce upon him and expose him the instant that you have seen through his trick. He is there to deceive you, and you are there to find him out. But what are you to do with the friend of your host's wife? Are you to turn on a light suddenly and expose her slapping a surreptitious banjo? Or are you to hurl cochineal over her evening frock when she steals round with her phosphorus bottle and her supernatural platitude? There would he a scene, and you would be looked upon as a brute. So you have your choice of being that or a dupe. I was in no very good humor as I followed Wilson to the lady.

Any one less like my idea of a West Indian could not be imagined. She was a small, frail creature, well over forty, I should say, with a pale, peaky face, and hair of a very light shade of chestnut. Her presence was insignificant and her manner retiring. In any group of ten women she would have been the last whom one would have picked out. Her eyes were perhaps her most remarkable, and also, I am compelled to say, her least pleasant, feature. They were gray in color, – gray with a shade of green, – and their expression struck me as being decidedly furtive. I wonder if furtive is the word, or should I have said fierce? On second thoughts, feline would have expressed it better. A crutch leaning against the wall told me what was painfully evident when she rose: that one of her legs was crippled.

So I was introduced to Miss Penclosa, and it did not escape me that as my name was mentioned she glanced across at Agatha. Wilson had evidently been talking. And presently, no doubt, thought I, she will inform me by occult means that I am engaged to a young lady with wheat-ears in her hair. I wondered how much more Wilson had been telling her about me.

"Professor Gilroy is a terrible sceptic," said he; "I hope, Miss Penclosa, that you will be able to convert him."

She looked keenly up at me.

"Professor Gilroy is quite right to be sceptical if he has not seen any thing convincing," said she. "I should have thought," she added, "that you would yourself have been an excellent subject."

"For what, may I ask?" said I.

"Well, for mesmerism, for example."

"My experience has been that mesmerists go for their subjects to those who are mentally unsound. All their results are vitiated, as it seems to me, by the fact that they are dealing with abnormal organisms."

"Which of these ladies would you say possessed a normal organism?" she asked. "I should like you to select the one who seems to you to have the best balanced mind. Should we say the girl in pink and white? – Miss Agatha Marden, I think the name is."

"Yes, I should attach weight to any results from her."

"I have never tried how far she is impressionable. Of course some people respond much more rapidly than others. May I ask how far your scepticism extends? I suppose that you admit the mesmeric sleep and the power of suggestion."

"I admit nothing, Miss Penclosa."

"Dear me, I thought science had got further than that. Of course I know nothing about the scientific side of it. I only know what I can do. You see the girl in red, for example, over near the Japanese jar. I shall will that she come across to us."

She bent forward as she spoke and dropped her fan upon the floor. The girl whisked round and came straight toward us, with an enquiring look upon her face, as if some one had called her.

"What do you think of that, Gilroy?" cried Wilson, in a kind of ecstasy.

I did not dare to tell him what I thought of it. To me it was the most barefaced, shameless piece of imposture that I had ever witnessed. The collusion and the signal had really been too obvious.

"Professor Gilroy is not satisfied," said she, glancing up at me with her strange little eyes. "My poor fan is to get the credit of that experiment. Well, we must try something else. Miss Marden, would you have any objection to my putting you off?"

"Oh, I should love it!" cried Agatha.

By this time all the company had gathered round us in a circle, the shirt-fronted men, and the white-throated women, some awed, some critical, as though it were something between a religious ceremony and a conjurer's entertainment. A red velvet arm-chair had been pushed into the centre, and Agatha lay back in it, a little flushed and trembling slightly from excitement. I could see it from the vibration of the wheat-ears. Miss Penclosa rose from her seat and stood over her, leaning upon her crutch.

And there was a change in the woman. She no longer seemed small or insignificant. Twenty years were gone from her age. Her eyes were shining, a tinge of color had come into her sallow cheeks, her whole figure had expanded. So I have seen a dull-eyed, listless lad change in an instant into briskness and life when given a task of which he felt himself master. She looked down at Agatha with an expression which I resented from the bottom of my soul – the expression with which a Roman empress might have looked at her kneeling slave. Then with a quick, commanding gesture she tossed up her arms and swept them slowly down in front of her.

I was watching Agatha narrowly. During three passes she seemed to be simply amused. At the fourth I observed a slight glazing of her eyes, accompanied by some dilation of her pupils. At the sixth there was a momentary rigor. At the seventh her lids began to droop. At the tenth her eyes were closed, and her breathing was slower and fuller than usual. I tried as I watched to preserve my scientific calm, but a foolish, causeless agitation convulsed me. I trust that I hid it, but I felt as a child feels in the dark. I could not have believed that I was still open to such weakness.

"She is in the trance," said Miss Penclosa.

"She is sleeping!" I cried.

"Wake her, then!"

I pulled her by the arm and shouted in her ear. She might have been dead for all the impression that I could make. Her body was there on the velvet chair. Her organs were acting – her heart, her lungs. But her soul! It had slipped from beyond our ken. Whither had it gone? What power had dispossessed it? I was puzzled and disconcerted.

"So much for the mesmeric sleep," said Miss Penclosa. "As regards suggestion, whatever I may suggest Miss Marden will infallibly do, whether it be now or after she has awakened from her trance. Do you demand proof of it?"

"Certainly," said I.

"You shall have it." I saw a smile pass over her face, as though an amusing thought had struck her. She stooped and whispered earnestly into her subject's ear. Agatha, who had been so deaf to me, nodded her head as she listened.

"Awake!" cried Miss Penclosa, with a sharp tap of her crutch upon the floor. The eyes opened, the glazing cleared slowly away, and the soul looked out once more after its strange eclipse.

We went away early. Agatha was none the worse for her strange excursion, but I was nervous and unstrung, unable to listen to or answer the stream of comments which Wilson was pouring out for my benefit. As I bade her good-night Miss Penclosa slipped a piece of paper into my hand.

"Pray forgive me," said she, "if I take means to overcome your scepticism. Open this note at ten o'clock to-morrow morning. It is a little private test."

I can't imagine what she means, but there is the note, and it shall be opened as she directs. My head is aching, and I have written enough for to-night. To– morrow I dare say that what seems so inexplicable will take quite another complexion. I shall not surrender my convictions without a struggle.

March 25. I am amazed, confounded. It is clear that I must reconsider my opinion upon this matter. But first let me place on record what has occurred.
