Let me try to reason it out! This woman, by her own explanation, can dominate my nervous organism. She can project herself into my body and take command of it. She has a parasite soul; yes, she is a parasite, a monstrous parasite. She creeps into my frame as the hermit crab does into the whelk's shell. I am powerless What can I do? I am dealing with forces of which I know nothing. And I can tell no one of my trouble. They would set me down as a madman. Certainly, if it got noised abroad, the university would say that they had no need of a devil-ridden professor. And Agatha! No, no, I must face it alone.

Chapter 3
 

   I read over my notes of what the woman said when she spoke about her powers. There is one point which fills me with dismay. She implies that when the influence is slight the subject knows what he is doing, but cannot control himself, whereas when it is strongly exerted he is absolutely unconscious. Now, I have always known what I did, though less so last night than on the previous occasions. That seems to mean that she has never yet exerted her full powers upon me. Was ever a man so placed before?
   Yes, perhaps there was, and very near me, too. Charles Sadler must know something of this! His vague words of warning take a meaning now. Oh, if I had only listened to him then, before I helped by these repeated sittings to forge the links of the chain which binds me! But I will see him today. I will apologize to him for having treated his warning so lightly. I will see if he can advise me.
   4 P. M. No, he cannot. I have talked with him, and he showed such surprise at the first words in which I tried to express my unspeakable secret that I went no further. As far as I can gather (by hints and inferences rather than by any statement), his own experience was limited to some words or looks such as I have myself endured. His abandonment of Miss Penclosa is in itself a sign that he was never really in her toils. Oh, if he only knew his escape! He has to thank his phlegmatic Saxon temperament for it. I am black and Celtic, and this hag's clutch is deep in my nerves. Shall I ever get it out? Shall I ever be the same man that I was just one short fortnight ago?
   Let me consider what I had better do. I cannot leave the university in the middle of the term. If I were free, my course would be obvious. I should start at once and travel in Persia. But would she allow me to start? And could her influence not reach me in Persia, and bring me back to within touch of her crutch? I can only find out the limits of this hellish power by my own bitter experience. I will fight and fight and fight-and what can I do more?
   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.
   It was all wonderfully clear, and yet disassociated from the rest of my life, as the incidents of even the most vivid dream might be. A peculiar double consciousness possessed me. There was the predominant alien will, which was bent upon drawing me to the side of its owner, and there was the feebler protesting personality, which I recognized as being myself, tugging feebly at the overmastering impulse as a led terrier might at its chain. I can remember recognizing these two conflicting forces, but I recall nothing of my walk, nor of how I was admitted to the house.
   Very vivid, however, is my recollection of how I met Miss Penclosa. She was reclining on the sofa in the little boudoir in which our experiments had usually been carried out. Her head was rested on her hand, and a tiger-skin rug had been partly drawn over her. She looked up expectantly as I entered, and, as the lamp– light fell upon her face, I could see that she was very pale and thin, with dark hollows under her eyes. She smiled at me, and pointed to a stool beside her. It was with her left hand that she pointed, and I, running eagerly forward, seized it,-I loathe myself as I think of it,-and pressed it passionately to my lips. Then, seating myself upon the stool, and still retaining her hand, I gave her the photograph which I had brought with me, and talked and talked and talked-of my love for her, of my grief over her illness, of my joy at her recovery, of the misery it was to me to be absent a single evening from her side. She lay quietly looking down at me with imperious eyes and her provocative smile. Once I remember that she passed her hand over my hair as one caresses a dog; and it gave me pleasure-the caress. I thrilled under it. I was her slave, body and soul, and for the moment I rejoiced in my slavery.
   And then came the blessed change. Never tell me that there is not a Providence! I was on the brink of perdition. My feet were on the edge. Was it a coincidence that at that very instant help should come? No, no, no; there is a Providence, and its hand has drawn me back. There is something in the universe stronger than this devil woman with her tricks. Ah, what a balm to my heart it is to think so!
   As I looked up at her I was conscious of a change in her. Her face, which had been pale before, was now ghastly. Her eyes were dull, and the lids drooped heavily over them. Above all, the look of serene confidence had gone from her features. Her mouth had weakened. Her forehead had puckered. She was frightened and undecided. And as I watched the change my own spirit fluttered and struggled, trying hard to tear itself from the grip which held it-a grip which, from moment to moment, grew less secure.
   "Austin," she whispered, "I have tried to do too much. I was not strong enough. I have not recovered yet from my illness. But I could not live longer without seeing you. You won't leave me, Austin? This is only a passing weakness. If you will only give me five minutes, I shall be myself again. Give me the small decanter from the table in the window."
   But I had regained my soul. With her waning strength the influence had cleared away from me and left me free. And I was aggressive-bitterly, fiercely aggressive. For once at least I could make this woman understand what my real feelings toward her were. My soul was filled with a hatred as bestial as the love against which it was a reaction. It was the savage, murderous passion of the revolted serf. I could have taken the crutch from her side and beaten her face in with it. She threw her hands up, as if to avoid a blow, and cowered away from me into the corner of the settee.
   "The brandy!" she gasped. "The brandy!"
   I took the decanter and poured it over the roots of a palm in the window. Then I snatched the photograph from her hand and tore it into a hundred pieces.
   "You vile woman," I said, "if I did my duty to society, you would never leave this room alive!"
   "I love you, Austin; I love you!" she wailed.
   "Yes," I cried, "and Charles Sadler before. And how many others before that?"
   "Charles Sadler!" she gasped. "He has spoken to you? So, Charles Sadler, Charles Sadler!" Her voice came through her white lips like a snake's hiss.
   "Yes, I know you, and others shall know you, too. You shameless creature! You knew how I stood. And yet you used your vile power to bring me to your side. You may, perhaps, do so again, but at least you will remember that you have heard me say that I love Miss Marden from the bottom of my soul, and that I loathe you, abhor you!
   The very sight of you and the sound of your voice fill me with horror and disgust. The thought of you is repulsive. That is how I feel toward you, and if it pleases you by your tricks to draw me again to your side as you have done Tonight, you will at least, I should think, have little satisfaction in trying to make a lover out of a man who has told you his real opinion of you. You may put what words you will into my mouth, but you cannot help remembering-"
   I stopped, for the woman's head had fallen back, and she had fainted. She could not bear to hear what I had to say to her! What a glow of satisfaction it gives me to think that, come what may, in the future she can never misunderstand my true feelings toward her. But what will occur in the future? What will she do next? I dare not think of it. Oh, if only I could hope that she will leave me alone! But when I think of what I said to her– Never mind; I have been stronger than she for once.
   April 11. I hardly slept last night, and found myself in the morning so unstrung and feverish that I was compelled to ask Pratt-Haldane to do my lecture for me. It is the first that I have ever missed. I rose at mid-day, but my head is aching, my hands quivering, and my nerves in a pitiable state.
   Who should come round this evening but Wilson. He has just come back from London, where he has lectured, read papers, convened meetings, exposed a medium, conducted a series of experiments on thought transference, entertained Professor Richet of Paris, spent hours gazing into a crystal, and obtained some evidence as to the passage of matter through matter. All this he poured into my ears in a single gust.
   "But you!" he cried at last. "You are not looking well. And Miss Penclosa is quite prostrated today. How about the experiments?"
   "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 w ell Tonight." 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!

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.
   April 26. Ten days have elapsed since I have had the heart to make any entry in my journal. Why should I record my own humiliation and degradation? I had vowed never to open it again. And yet the force of habit is strong, and here I find myself taking up once more the record of my own dreadful experiences-in much the same spirit in which a suicide has been known to take notes of the effects of the poison which killed him.
   Well, the crash which I had foreseen has come-and that no further back than yesterday. The university authorities have taken my lectureship from me. It has been done in the most delicate way, purporting to be a temporary measure to relieve me from the effects of overwork, and to give me the opportunity of recovering my health. None the less, it has been done, and I am no longer Professor Gilroy. The laboratory is still in my charge, but I have little doubt that that also will soon go.
   The fact is that my lectures had become the laughing– stock of the university. My class was crowded with students who came to see and hear what the eccentric professor would do or say next. I cannot go into the detail of my humiliation. Oh, that devilish woman! There is no depth of buffoonery and imbecility to which she has not forced me. I would begin my lecture clearly and well, but always with the sense of a coming eclipse. Then as I felt the influence I would struggle against it, striving with clenched hands and beads of sweat upon my brow to get the better of it, while the students, hearing my incoherent words and watching my contortions, would roar with laughter at the antics of their professor. And then, when she had once fairly mastered me, out would come the most outrageous things-silly jokes, sentiments as though I were proposing a toast, snatches of ballads, personal abuse even against some member of my class. And then in a moment my brain would clear again, and my lecture would proceed decorously to the end. No wonder that my conduct has been the talk of the colleges. No wonder that the University Senate has been compelled to take official notice of such a scandal. Oh, that devilish woman!
   And the most dreadful part of it all is my own loneliness. Here I sit in a commonplace English bow– window, looking out upon a commonplace English street with its garish 'buses and its lounging policeman, and behind me there hangs a shadow which is out of all keeping with the age and place. In the home of knowledge I am weighed down and tortured by a power of which science knows nothing. No magistrate would listen to me. No paper would discuss my case. No doctor would believe my symptoms. My own most intimate friends would only look upon it as a sign of brain derangement. I am out of all touch with my kind. Oh, that devilish woman! Let her have a care! She may push me too far. When the law cannot help a man, he may make a law for himself.
   She met me in the High Street yesterday evening and spoke to me. It was as well for her, perhaps, that it was not between the hedges of a lonely country road. She asked me with her cold smile whether I had been chastened yet. I did not deign to answer her. "We must try another turn of the screw;" said she. Have a care, my lady, have a care! I had her at my mercy once. Perhaps another chance may come.
   April 28. The suspension of my lectureship has had the effect also of taking away her means of annoying me, and so I have enjoyed two blessed days of peace. After all, there is no reason to despair. Sympathy pours in to me from all sides, and every one agrees that it is my devotion to science and the arduous nature of my researches which have shaken my nervous system. I have had the kindest message from the council advising me to travel abroad, and expressing the confident hope that I may be able to resume all my duties by the beginning of the summer term. Nothing could be more flattering than their allusions to my career and to my services to the university. It is only in misfortune that one can test one's own popularity. This creature may weary of tormenting me, and then all may yet be well. May God grant it!
   April 29. Our sleepy little town has had a small sensation. The only knowledge of crime which we ever have is when a rowdy undergraduate breaks a few lamps or comes to blows with a policeman. Last night, however, there was an attempt made to break-into the branch of the Bank of England, and we are all in a flutter in consequence.
   Parkenson, the manager, is an intimate friend of mine, and I found him very much excited when I walked round there after breakfast. Had the thieves broken into the counting-house, they would still have had the safes to reckon with, so that the defence was considerably stronger than the attack. Indeed, the latter does not appear to have ever been very formidable. Two of the lower windows have marks as if a chisel or some such instrument had been pushed under them to force them open. The police should have a good clue, for the wood-work had been done with green paint only the day before, and from the smears it is evident that some of it has found its way on to the criminal's hands or clothes.
   4.30 P. M. Ah, that accursed woman! That thrice accursed woman! Never mind! She shall not beat me! No, she shall not! But, oh, the she-devil! She has taken my professorship. Now she would take my honor. Is there nothing I can do against her, nothing save– Ah, but, hard pushed as I am, I cannot bring myself to think of that!
   It was about an hour ago that I went into my bedroom, and was brushing my hair before the glass, when suddenly my eyes lit upon something which left me so sick and cold that I sat down upon the edge of the bed and began to cry. It is many a long year since I shed tears, but all my nerve was gone, and I could but sob and sob in impotent grief and anger. There was my house jacket, the coat I usually wear after dinner, hanging on its peg by the wardrobe, with the right sleeve thickly crusted from wrist to elbow with daubs of green paint.
   So this was what she meant by another turn of the screw! She had made a public imbecile of me. Now she would brand me as a criminal. This time she has failed. But how about the next? I dare not think of it-and of Agatha and my poor old mother! I wish that I were dead!
   Yes, this is the other turn of the screw. And this is also what she meant, no doubt, when she said that I had not realized yet the power she has over me. I look back at my account of my conversation with her, and I see how she declared that with a slight exertion of her will her subject would be conscious, and with a stronger one unconscious. Last night I was unconscious. I could have sworn that I slept soundly in my bed without so much as a dream. And yet those stains tell me that I dressed, made my way out, attempted to open the bank windows, and returned. Was I observed? Is it possible that some one saw me do it and followed me home? Ah, what a hell my life has become! I have no peace, no rest. But my patience is nearing its end.
   10 P. M. I have cleaned my coat with turpentine. I do not think that any one could have seen me. It was with my screw-driver that I made the marks. I found it all crusted with paint, and I have cleaned it. My head aches as if it would burst, and I have taken five grains of antipyrine. If it were not for Agatha, I should have taken fifty and had an end of it.
   May 3. Three quiet days. This hell fiend is like a cat with a mouse. She lets me loose only to pounce upon me again. I am never so frightened as when every thing is still. My physical state is deplorable– perpetual hiccough and ptosis of the left eyelid.
   I have heard from the Mardens that they will be back the day after tomorrow. I do not know whether I am glad or sorry. They were safe in London. Once here they may be drawn into the miserable network in which I am myself struggling. And I must tell them of it. I cannot marry Agatha so long as I know that I am not responsible for my own actions. Yes, I must tell them, even if it brings every thing to an end between us.
   Tonight is the university ball, and I must go. God knows I never felt less in the humor for festivity, but I must not have it said that I am unfit to appear in public. If I am seen there, and have speech with some of the elders of the university it will go a long way toward showing them that it would be unjust to take my chair away from me.
   10 P. M. I have been to the ball. Charles Sadler and I went together, but I have come away before him. I shall wait up for him, however, for, indeed, I fear to go to sleep these nights. He is a cheery, practical fellow, and a chat with him will steady my nerves. On the whole, the evening was a great success. I talked to every one who has influence, and I think that I made them realize that my chair is not vacant quite yet. The creature was at the ball-unable to dance, of course, but sitting with Mrs. Wilson. Again and again her eyes rested upon me. They were almost the last things I saw before I left the room. Once, as I sat sideways to her, I watched her, and saw that her gaze was following some one else. It was Sadler, who was dancing at the time with the second Miss Thurston. To judge by her expression, it is well for him that he is not in her grip as I am. He does not know the escape he has had. I think I hear his step in the street now, and I will go down and let him in. If he will-
   May 4. Why did I break off in this way last night? I never went down stairs, after all-at least, I have no recollection of doing so. But, on the other hand, I cannot remember going to bed. One of my hands is greatly swollen this morning, and yet I have no remembrance of injuring it yesterday. Otherwise, I am feeling all the better for last night's festivity. But I cannot understand how it is that I did not meet Charles Sadler when I so fully intended to do so. Is it possible– My God, it is only too probable! Has she been leading me some devil's dance again? I will go down to Sadler and ask him.
   Mid-day. The thing has come to a crisis. My life is not worth living. But, if I am to die, then she shall come also. I will not leave her behind, to drive some other man mad as she has me. No, I have come to the limit of my endurance. She has made me as desperate and dangerous a man as walks the earth. God knows I have never had the heart to hurt a fly, and yet, if I had my hands now upon that woman, she should never leave this room alive. I shall see her this very day, and she shall learn what she has to expect from me.
   I went to Sadler and found him, to my surprise, in bed. As I entered he sat up and turned a face toward me which sickened me as I looked at it.
   "Why, Sadler, what has happened?" I cried, but my heart turned cold as I said it.
   "Gilroy," he answered, mumbling with his swollen lips, "I have for some weeks been under the impression that you are a madman. Now I know it, and that you are a dangerous one as well. If it were not that I am unwilling to make a scandal in the college, you would now be in the hands of the police."
   "Do you mean-" I cried.
   "I mean that as I opened the door last night you rushed out upon me, struck me with both your fists in the face, knocked me down, kicked me furiously in the side, and left me lying almost unconscious in the street. Look at your own hand bearing witness against you."
   Yes, there it was, puffed up, with sponge-like knuckles, as after some terrific blow. What could I do? Though he put me down as a madman, I must tell him all. I sat by his bed and went over all my troubles from the beginning. I poured them out with quivering hands and burning words which might have carried conviction to the most sceptical. "She hates you and she hates me!" I cried. "She revenged herself last night on both of us at once. She saw me leave the ball, and she must have seen you also. She knew how long it would take you to reach home. Then she had but to use her wicked will. Ah, your bruised face is a small thing beside my bruised soul!"
   He was struck by my story. That was evident. "Yes, yes, she watched me out of the room," he muttered. "She is capable of it. But is it possible that she has really reduced you to this? What do you intend to do?"
   "To stop it!" I cried. "I am perfectly desperate; I shall give her fair warning today, and the next time will be the last."
   "Do nothing rash," said he.
   "Rash!" I cried. "The only rash thing is that I should postpone it another hour." With that I rushed to my room, and here I am on the eve of what may be the great crisis of my life. I shall start at once. I have gained one thing today, for I have made one man, at least, realize the truth of this monstrous experience of mine. And, if the worst should happen, this diary remains as a proof of the goad that has driven me.
   Evening. When I came to Wilson's, I was shown up, and found that he was sitting with Miss Penclosa. For half an hour I had to endure his fussy talk about his recent research into the exact nature of the spiritualistic rap, while the creature and I sat in silence looking across the room at each other. I read a sinister amusement in her eyes, and she must have seen hatred and menace in mine. I had almost despaired of having speech with her when he was called from the room, and we were left for a few moments together.
   "Well, Professor Gilroy-or is it Mr. Gilroy?" said she, with that bitter smile of hers. "How is your friend Mr. Charles Sadler after the ball?"
   "You fiend!" I cried. "You have come to the end of your tricks now. I will have no more of them. Listen to what I say." I strode across and shook her roughly by the shoulder "As sure as there is a God in heaven, I swear that if you try another of your deviltries upon me I will have your life for it. Come what may, I will have your life. I have come to the end of what a man can endure."
   "Accounts are not quite settled between us," said she, with a passion that equalled my own. "I can love, and I can hate. You had your choice. You chose to spurn the first; now you must test the other. It will take a little more to break your spirit, I see, but broken it shall be. Miss Marden comes back tomorrow, as I understand."
   "What has that to do with you?" I cried. "It is a pollution that you should dare even to think of her. If I thought that you would harm her-"
   She was frightened, I could see, though she tried to brazen it out. She read the black thought in my mind, and cowered away from me.
   "She is fortunate in having such a champion," said she. "He actually dares to threaten a lonely woman. I must really congratulate Miss Marden upon her protector."
   The words were bitter, but the voice and manner were more acid still.
   "There is no use talking," said I. "I only came here to tell you,-and to tell you most solemnly,-that your next outrage upon me will be your last." With that, as I heard Wilson's step upon the stair, I walked from the room. Ay, she may look venomous and deadly, but, for all that, she is beginning to see now that she has as much to fear from me as I can have from her. Murder! It has an ugly sound. But you don't talk of murdering a snake or of murdering a tiger. Let her have a care now.
   May 5. I met Agatha and her mother at the station at eleven o'clock. She is looking so bright, so happy, so beautiful. And she was so overjoyed to see me. What have I done to deserve such love? I went back home with them, and we lunched together. All the troubles seem in a moment to have been shredded back from my life. She tells me that I am looking pale and worried and ill. The dear child puts it down to my loneliness and the perfunctory attentions of a housekeeper. I pray that she may never know the truth! May the shadow, if shadow there must be, lie ever black across my life and leave hers in the sunshine. I have just come back from them, feeling a new man. With her by my side I think that I could show a bold face to any thing which life might send.
   5 P. M. Now, let me try to be accurate. Let me try to say exactly how it occurred. It is fresh in my mind, and I can set it down correctly, though it is not likely that the time will ever come when I shall forget the doings of today.
   I had returned from the Mardens' after lunch, and was cutting some microscopic sections in my freezing microtome, when in an instant I lost consciousness in the sudden hateful fashion which has become only too familiar to me of late.
   When my senses came back to me I was sitting in a small chamber, very different from the one in which I had been working. It was cosey and bright, with chintz– covered settees, colored hangings, and a thousand pretty little trifles upon the wall. A small ornamental clock ticked in front of me, and the hands pointed to half-past three. It was all quite familiar to me, and yet I stared about for a moment in a half– dazed way until my eyes fell upon a cabinet photograph of myself upon the top of the piano. On the other side stood one of Mrs. Marden. Then, of course, I remembered where I was. It was Agatha's boudoir.
   But how came I there, and what did I want? A horrible sinking came to my heart. Had I been sent here on some devilish errand? Had that errand already been done? Surely it must; otherwise, why should I be allowed to come back to consciousness? Oh, the agony of that moment! What had I done? I sprang to my feet in my despair, and as I did so a small glass bottle fell from my knees on to the carpet.
   It was unbroken, and I picked it up. Outside was written "Sulphuric Acid. Fort." When I drew the round glass stopper, a thick fume rose slowly up, and a pungent, choking smell pervaded the room. I recognized it as one which I kept for chemical testing in my chambers. But why had I brought a bottle of vitriol into Agatha's chamber? Was it not this thick, reeking liquid with which jealous women had been known to mar the beauty of their rivals? My heart stood still as I held the bottle to the light. Thank God, it was full! No mischief had been done as yet. But had Agatha come in a minute sooner, was it not certain that the hellish parasite within me would have dashed the stuff into her– Ah, it will not bear to be thought of! But it must have been for that. Why else should I have brought it? At the thought of what I might have done my worn nerves broke down, and I sat shivering and twitching, the pitiable wreck of a man.
   It was the sound of Agatha's voice and the rustle of her dress which restored me. I looked up, and saw her blue eyes, so full of tenderness and pity, gazing down at me.
   "We must take you away to the country, Austin," she said. "You want rest and quiet. You look wretchedly ill."
   "Oh, it is nothing!" said I, trying to smile. "It was only a momentary weakness. I am all right again now."
   "I am so sorry to keep you waiting. Poor boy, you must have been here quite half an hour! The vicar was in the drawing-room, and, as I knew that you did not care for him, I thought it better that Jane should show you up here. I thought the man would never go!"
   "Thank God he stayed! Thank God he stayed!" I cried hysterically.
   "Why, what is the matter with you, Austin?" she asked, holding my arm as I staggered up from the chair. "Why are you glad that the vicar stayed? And what is this little bottle in your hand?"
   "Nothing," I cried, thrusting it into my pocket. "But I must go. I have something important to do."
   "How stern you look, Austin! I have never seen your face like that. You are angry?"
   "Yes, I am angry."
   "But not with me?"
   "No, no, my darling! You would not understand."
   "But you have not told me why you came."
   "I came to ask you whether you would always love me-no matter what I did, or what shadow might fall on my name. Would you believe in me and trust me however black appearances might be against me?"
   "You know that I would, Austin."
   "Yes, I know that you would. What I do I shall do for you. I am driven to it. There is no other way out, my darling!" I kissed her and rushed from the room.
   The time for indecision was at an end. As long as the creature threatened my own prospects and my honor there might be a question as to what I should do. But now, when Agatha-my innocent Agatha-was endangered, my duty lay before me like a turnpike road. I had no weapon, but I never paused for that. What weapon should I need, when I felt every muscle quivering with the strength of a frenzied man? I ran through the streets, so set upon what I had to do that I was only dimly conscious of the faces of friends whom I met– dimly conscious also that Professor Wilson met me, running with equal precipitance in the opposite direction. Breathless but resolute I reached the house and rang the bell. A white cheeked maid opened the door, and turned whiter yet when she saw the face that looked in at her.
   "Show me up at once to Miss Penclosa," I demanded.
   "Sir," she gasped, "Miss Penclosa died this afternoon at half-past three!"
