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!

Chapter 4

6.45 P. M. No, it is useless. There is no human help for me; I must fight this out single-handed. Two courses lie before me. I might become this woman's lover. Or I must endure such persecutions as she can inflict upon me. Even if none come, I shall live in a hell of apprehension. But she may torture me, she may drive me mad, she may kill me: I will never, never, never give in. What can she inflict which would be worse than the loss of Agatha, and the knowledge that I am a perjured liar, and have forfeited the name of gentleman?

Pratt-Haldane was most amiable, and listened with all politeness to my story. But when I looked at his heavy set features, his slow eyes, and the ponderous study furniture which surrounded him, I could hardly tell him what I had come to say. It was all so substantial, so material. And, besides, what would I myself have said a short month ago if one of my colleagues had come to me with a story of demonic possession? Perhaps. I should have been less patient than he was. As it was, he took notes of my statement, asked me how much tea I drank, how many hours I slept, whether I had been overworking much, had I had sudden pains in the head, evil dreams, singing in the ears, flashes before the eyes-all questions which pointed to his belief that brain congestion was at the bottom of my trouble. Finally he dismissed me with a great many platitudes about open-air exercise, and avoidance of nervous excitement. His prescription, which was for chloral and bromide, I rolled up and threw into the gutter.

No, I can look for no help from any human being. If I consult any more, they may put their heads together and I may find myself in an asylum. I can but grip my courage with both hands, and pray that an honest man may not be abandoned.

April 10. It is the sweetest spring within the memory of man. So green, so mild, so beautiful t Ah, what a contrast between nature without and my own soul so torn with doubt and terror! It has been an uneventful day, but I know that I am on the edge of an abyss. I know it, and yet I go on with the routine of my life. The one bright spot is that Agatha is happy and well and out of all danger. If this creature had a hand on each of us, what might she not do?

April 16. The woman is ingenious in her torments. She knows how fond I am of my work, and how highly my lectures are thought of. So it is from that point that she now attacks me. It will end, I can see, in my losing my professorship, but I will fight to the finish. She shall not drive me out of it without a struggle.

I was not conscious of any change during my lecture this morning save that for a minute or two I had a dizziness and swimminess which rapidly passed away. On the contrary, I congratulated myself upon having made my subject (the functions of the red corpuscles) both interesting and clear. I was surprised, therefore, when a student came into my laboratory immediately after the lecture, and complained of being puzzled by the discrepancy between my statements and those in the text books. He showed me his note-book, in which I was reported as having in one portion of the lecture championed the most outrageous and unscientific heresies. Of course I denied it, and declared that he had misunderstood me, but on comparing his notes with those of his companions, it became clear that he was right, and that I really had made some most preposterous statements. Of course I shall explain it away as being the result of a moment of aberration, but I feel only too sure that it will be the first of a series. It is but a month now to the end of the session, and I pray that I may be able to hold out until then.
