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.
