"I have abandoned them."

"Tut, tut! Why?"

"The subject seems to me to be a dangerous one."

Out came his big brown note-book.

"This is of great interest," said he. "What are your grounds for saying that it is a dangerous one? Please give your facts in chronological order, with approximate dates and names of reliable witnesses with their permanent addresses."

"First of all," I asked, "would you tell me whether you have collected any cases where the mesmerist has gained a command over the subject and has used it for evil purposes?"

"Dozens!" he cried exultantly. "Crime by suggestion——"

"I don't mean suggestion. I mean where a sudden impulse comes from a person at a distance—an uncontrollable impulse."

"Obsession!" he shrieked, in an ecstasy of delight. "It is the rarest condition. We have eight cases, five well attested. You don't mean to say——" His exultation made him hardly articulate.

"No, I don't," said I. "Good-evening! You will excuse me, but I am not very well to-night." And so at last I got rid of him, still brandishing his pencil and his note-book. My troubles may be bad to hear, but at least it is better to hug them to myself than to have myself exhibited by Wilson, like a freak at a fair. He has lost sight of human beings. Every thing to him is a case and a phenomenon. I will die before I speak to him again upon the matter.

April 12. Yesterday was a blessed day of quiet, and I enjoyed an uneventful night. Wilson's presence is a great consolation. What can the woman do now? Surely, when she has heard me say what I have said, she will conceive the same disgust for me which I have for her. She could not, no, she COULD not, desire to have a lover who had insulted her so. No, I believe I am free from her love—but how about her hate? Might she not use these powers of hers for revenge? Tut! why should I frighten myself over shadows? She will forget about me, and I shall forget about her, and all will be well.

April 13. My nerves have quite recovered their tone. I really believe that I have conquered the creature. But I must confess to living in some suspense. She is well again, for I hear that she was driving with Mrs. Wilson in the High Street in the afternoon.

April 14. I do wish I could get away from the place altogether. I shall fly to Agatha's side the very day that the term closes. I suppose it is pitiably weak of me, but this woman gets upon my nerves most terribly. I have seen her again, and I have spoken with her.

It was just after lunch, and I was smoking a cigarette in my study, when I heard the step of my servant Murray in the passage. I was languidly conscious that a second step was audible behind, and had hardly troubled myself to speculate who it might be, when suddenly a slight noise brought me out of my chair with my skin creeping with apprehension. I had never particularly observed before what sort of sound the tapping of a crutch was, but my quivering nerves told me that I heard it now in the sharp wooden clack which alternated with the muffled thud of the foot fall. Another instant and my servant had shown her in.

I did not attempt the usual conventions of society, nor did she. I simply stood with the smouldering cigarette in my hand, and gazed at her. She in her turn looked silently at me, and at her look I remembered how in these very pages I had tried to define the expression of her eyes, whether they were furtive or fierce. To-day they were fierce—coldly and inexorably so.

"Well," said she at last, "are you still of the same mind as when I saw you last?"

"I have always been of the same mind."

"Let us understand each other, Professor Gilroy," said she slowly. "I am not a very safe person to trifle with, as you should realize by now. It was you who asked me to enter into a series of experiments with you, it was you who won my affections, it was you who professed your love for me, it was you who brought me your own photograph with words of affection upon it, and, finally, it was you who on the very same evening thought fit to insult me most outrageously, addressing me as no man has ever dared to speak to me yet. Tell me that those words came from you in a moment of passion and I am prepared to forget and to forgive them. You did not mean what you said, Austin? You do not really hate me?"

I might have pitied this deformed woman—such a longing for love broke suddenly through the menace of her eyes. But then I thought of what I had gone through, and my heart set like flint.

"If ever you heard me speak of love," said I, "you know very well that it was your voice which spoke, and not mine. The only words of truth which I have ever been able to say to you are those which you heard when last we met."

"I know. Some one has set you against me. It was he!" She tapped with her crutch upon the floor. "Well, you know very well that I could bring you this instant crouching like a spaniel to my feet. You will not find me again in my hour of weakness, when you can insult me with impunity. Have a care what you are doing, Professor Gilroy. You stand in a terrible position. You have not yet realized the hold which I have upon you."

I shrugged my shoulders and turned away.

"Well," said she, after a pause, "if you despise my love, I must see what can be done with fear. You smile, but the day will come when you will come screaming to me for pardon. Yes, you will grovel on the ground before me, proud as you are, and you will curse the day that ever you turned me from your best friend into your most bitter enemy. Have a care, Professor Gilroy!" I saw a white hand shaking in the air, and a face which was scarcely human, so convulsed was it with passion. An instant later she was gone, and I heard the quick hobble and tap receding down the passage.

But she has left a weight upon my heart. Vague presentiments of coming misfortune lie heavy upon me. I try in vain to persuade myself that these are only words of empty anger. I can remember those relentless eyes too clearly to think so. What shall I do—ah, what shall I do? I am no longer master of my own soul. At any moment this loathsome parasite may creep into me, and then—— I must tell some one my hideous secret—I must tell it or go mad. If I had some one to sympathize and advise! Wilson is out of the question. Charles Sadler would understand me only so far as his own experience carries him. Pratt-Haldane! He is a well-balanced man, a man of great common-sense and resource. I will go to him. I will tell him every thing. God grant that he may be able to advise me!
