My brain is quite clear again now, and I can think over what has occurred. It is absurd to suppose that it is merely weakness and force of habit. I tried to explain it in that way the other night, but it will no longer suffice. It is something much deeper and more terrible than that. Why, when I was at the Mardens' whist-table, I was dragged away as if the noose of a rope had been cast round me. I can no longer disguise it from myself. The woman has her grip upon me. I am in her clutch. But I must keep my head and reason it out and see what is best to be done.
But what a blind fool I have been! In my enthusiasm over my research I have walked straight into the pit, although it lay gaping before me. Did she not herself warn me? Did she not tell me, as I can read in my own journal, that when she has acquired power over a subject she can make him do her will? And she has acquired that power over me. I am for the moment at the beck and call of this creature with the crutch. I must come when she wills it. I must do as she wills. Worst of all, I must feel as she wills. I loathe her and fear her, yet, while I am under the spell, she can doubtless make me love her.
There is some consolation in the thought, then, that those odious impulses for which I have blamed myself do not really come from me at all. They are all transferred from her, little as I could have guessed it at the time. I feel cleaner and lighter for the thought.
April 8.
Yes, now, in broad daylight, writing coolly and with time for reflection, I am compelled to confirm every thing which I wrote in my journal last night. I am in a horrible position, but, above all, I must not lose my head. I must pit my intellect against her powers. After all, I am no silly puppet, to dance at the end of a string. I have energy, brains, courage. For all her devil's tricks I may beat her yet. May! I MUST, or what is to become of me?
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.
