I know very well that about eight o'clock Tonight that craving for her society, that irresistible restlessness, will come upon me. How shall I overcome it? What shall I do? I must make it impossible for me to leave the room. I shall lock the door and throw the key out of the window. But, then, what am I to do in the morning? Never mind about the morning. I must at all costs break this chain which holds me.

April 9. Victory! I have done splendidly! At seven o'clock last night I took a hasty dinner, and then locked myself up in my bedroom and dropped the key into the garden. I chose a cheery novel, and lay in bed for three hours trying to read it, but really in a horrible state of trepidation, expecting every instant that I should become conscious of the impulse. Nothing of the sort occurred, however, and I awoke this morning with the feeling that a black nightmare had been lifted off me. Perhaps the creature realized what I had done, and understood that it was useless to try to influence me. At any rate, I have beaten her once, and if I can do it once, I can do it again.

It was most awkward about the key in the morning. Luckily, there was an under-gardener below, and I asked him to throw it up. No doubt he thought I had just dropped it. I will have doors and windows screwed up and six stout men to hold me down in my bed before I will surrender myself to be hag-ridden in this way.

I had a note from Mrs. Marden this afternoon asking me to go round and see her. I intended to do so in any case, but had not excepted to find bad news waiting for me. It seems that the Armstrongs, from whom Agatha has expectations, are due home from Adelaide in the Aurora, and that they have written to Mrs. Marden and her to meet them in town. They will probably be away for a month or six weeks, and, as the Aurora is due on Wednesday, they must go at once-tomorrow, if they are ready in time. My consolation is that when we meet again there will be no more parting between Agatha and me.

"I want you to do one thing, Agatha," said I, when we were alone together. "If you should happen to meet Miss Penclosa, either in town or here, you must promise me never again to allow her to mesmerize you."

Agatha opened her eyes.

"Why, it was only the other day that you were saying how interesting it all was, and how determined you were to finish your experiments."

"I know, but I have changed my mind since then."

"And you won't have it any more?"

"No."

"I am so glad, Austin. You can't think how pale and worn you have been lately. It was really our principal objection to going to London now that we did not wish to leave you when you were so pulled down. And your manner has been so strange occasionally-especially that night when you left poor Professor Pratt-Haldane to play dummy. I am convinced that these experiments are very bad for your nerves."

"I think so, too, dear."

"And for Miss Penclosa's nerves as well. You have heard that she is ill?"

"No."

"Mrs. Wilson told us so last night. She described it as a nervous fever Professor Wilson is coming back this week, and of course Mrs. Wilson is very anxious that Miss Penclosa should be well again then, for he has quite a programme of experiments which he is anxious to carry out."

I was glad to have Agatha's promise, for it was enough that this woman should have one of us in her clutch. On the other hand, I was disturbed to hear about Miss Penclosa's illness. It rather discounts the victory which I appeared to win last night. I remember that she said that loss of health interfered with her power. That may be why I was able to hold my own so easily. Well, well, I must take the same precautions Tonight and see what comes of it. I am childishly frightened when I think of her.

April 10. All went very well last night. I was amused at the gardener's face when I had again to hail him this morning and to ask him to throw up my key. I shall get a name among the servants if this sort of thing goes on. But the great point is that I stayed in my room without the slightest inclination to leave it. I do believe that I am shaking myself clear of this incredible bond-or is it only that the woman's power is in abeyance until she recovers her strength? I can but pray for the best.

The Mardens left this morning, and the brightness seems to have gone out of the spring sunshine. And yet it is very beautiful also as it gleams on the green chestnuts opposite my windows, and gives a touch of gayety to the heavy, lichen-mottled walls of the old colleges. How sweet and gentle and soothing is Nature! Who would think that there lurked in her also such vile forces, such odious possibilities! For of course I understand that this dreadful thing which has sprung out at me is neither supernatural nor even preternatural. No, it is a natural force which this woman can use and society is ignorant of. The mere fact that it ebbs with her strength shows how entirely it is subject to physical laws. If I had time, I might probe it to the bottom and lay my hands upon its antidote. But you cannot tame the tiger when you are beneath his claws. You can but try to writhe away from him. Ah, when I look in the glass and see my own dark eyes and clear-cut Spanish face, I long for a vitriol splash or a bout of the small-pox. One or the other might have saved me from this calamity.

I am inclined to think that I may have trouble to– night. There are two things which make me fear so. One is that I met Mrs. Wilson in the street, and that she tells me that Miss Penclosa is better, though still weak. I find myself wishing in my heart that the illness had been her last. The other is that Professor Wilson comes back in a day or two, and his presence would act as a constraint upon her. I should not fear our interviews if a third person were present. For both these reasons I have a presentiment of trouble to– night, and I shall take the same precautions as before.

April 10. No, thank God, all went well last night. I really could not face the gardener again. I locked my door and thrust the key underneath it, so that I had to ask the maid to let me out in the morning. But the precaution was really not needed, for I never had any inclination to go out at all. Three evenings in succession at home! I am surely near the end of my troubles, for Wilson will be home again either today or tomorrow. Shall I tell him of what I have gone through or not? I am convinced that I should not have the slightest sympathy from him. He would look upon me as an interesting case, and read a paper about me at the next meeting of the Psychical Society, in which he would gravely discuss the possibility of my being a deliberate liar, and weigh it against the chances of my being in an early stage of lunacy. No, I shall get no comfort out of Wilson.

I am feeling wonderfully fit and well. I don't think I ever lectured with greater spirit. Oh, if I could only get this shadow off my life, how happy I should be! Young, fairly wealthy, in the front rank of my profession, engaged to a beautiful and charming girl– have I not every thing which a man could ask for? Only one thing to trouble me, but what a thing it is!

Midnight. I shall go mad. Yes, that will be the end of it. I shall go mad. I am not far from it now. My head throbs as I rest it on my hot hand. I am quivering all over like a scared horse. Oh, what a night I have had! And yet I have some cause to be satisfied also.

At the risk of becoming the laughing-stock of my own servant, I again slipped my key under the door, imprisoning myself for the night. Then, finding it too early to go to bed, I lay down with my clothes on and began to read one of Dumas's novels. Suddenly I was gripped-gripped and dragged from the couch. It is only thus that I can describe the overpowering nature of the force which pounced upon me. I clawed at the coverlet. I clung to the wood-work. I believe that I screamed out in my frenzy. It was all useless, hopeless. I MUST go. There was no way out of it. It was only at the outset that I resisted. The force soon became too overmastering for that. I thank goodness that there were no watchers there to interfere with me. I could not have answered for myself if there had been. And, besides the determination to get out, there came to me, also, the keenest and coolest judgment in choosing my means. I lit a candle and endeavored, kneeling in front of the door, to pull the key through with the feather-end of a quill pen. It was just too short and pushed it further away. Then with quiet persistence I got a paper-knife out of one of the drawers, and with that I managed to draw the key back. I opened the door, stepped into my study, took a photograph of myself from the bureau, wrote something across it, placed it in the inside pocket of my coat, and then started off for Wilson's.
