Necronomicon- Consciousness Transference

During our sunset dash through Portland the muttering commenced again, more distinctly than before, and as I listened I caught a stream of utterly insane drivel about Asenath. The extent to which she had preyed on Edward’s nerves was plain, for he had woven a whole set of hallucinations around her. His present predicament, he mumbled furtively, was only one of a long series. She was getting hold of him, and he knew that some day she would never let go. Even now she probably let him go only when she had to, because she couldn’t hold on long at a time. She constantly took his body and went to nameless places for nameless rites, leaving him in her body and locking him upstairs—but sometimes she couldn’t hold on, and he would find himself suddenly in his own body again in some far-off, horrible, and perhaps unknown place. Sometimes she’d get hold of him again and sometimes she couldn’t. Often he was left stranded somewhere as I had found him . . . time and again he had to find his way home from frightful distances, getting somebody to drive the car after he found it.
     The worst thing was that she was holding on to him longer and longer at a time. She wanted to be a man—to be fully human—that was why she got hold of him. She had sensed the mixture of fine-wrought brain and weak will in him. Some day she would crowd him out and disappear with his body—disappear to become a great magician like her father and leave him marooned in that female shell that wasn’t even quite human. Yes, he knew about the Innsmouth blood now. There had been traffick with things from the sea—it was horrible. . . . And old Ephraim—he had known the secret, and when he grew old did a hideous thing to keep alive . . . he wanted to live forever . . . Asenath would succeed—one successful demonstration had taken place already.
     As Derby muttered on I turned to look at him closely, verifying the impression of change which an earlier scrutiny had given me. Paradoxically, he seemed in better shape than usual—harder, more normally developed, and without the trace of sickly flabbiness caused by his indolent habits. It was as if he had been really active and properly exercised for the first time in his coddled life, and I judged that Asenath’s force must have pushed him into unwonted channels of motion and alertness. But just now his mind was in a pitiable state; for he was mumbling wild extravagances about his wife, about black magic, about old Ephraim, and about some revelation which would convince even me. He repeated names which I recognised from bygone browsings in forbidden volumes, and at times made me shudder with a certain thread of mythological consistency—of convincing coherence—which ran through his maundering. Again and again he would pause, as if to gather courage for some final and terrible disclosure.
     “Dan, Dan, don’t you remember him—the wild eyes and the unkempt beard that never turned white? He glared at me once, and I never forgot it. Now she glares that way. And I know why! He found it in the Necronomicon—the formula. I don’t dare tell you the page yet, but when I do you can read and understand. Then you will know what has engulfed me. On, on, on, on—body to body to body—he means never to die. The life-glow—he knows how to break the link . . . it can flicker on a while even when the body is dead. I’ll give you hints, and maybe you’ll guess. Listen, Dan—do you know why my wife always takes such pains with that silly backhand writing? Have you ever seen a manuscript of old Ephraim’s? Do you want to know why I shivered when I saw some hasty notes Asenath had jotted down?
“Asenath . . . is there such a person? Why did they half think there was poison in old Ephraim’s stomach? Why do the Gilmans whisper about the way he shrieked—like a frightened child—when he went mad and Asenath locked him up in the padded attic room where—the other—had been? Was it old Ephraim’s soul that was locked in? Who locked in whom? Why had he been looking for months for someone with a fine mind and a weak will? Why did he curse that his daughter wasn’t a son? Tell me, Daniel Upton—what devilish exchange was perpetrated in the house of horror where that blasphemous monster had his trusting, weak-willed, half-human child at his mercy? Didn’t he make it permanent—as she’ll do in the end with me? Tell me why that thing that calls itself Asenath writes differently when off guard, so that you can’t tell its script from . . .”
     Then the thing happened. Derby’s voice was rising to a thin treble scream as he raved, when suddenly it was shut off with an almost mechanical click. I thought of those other occasions at my home when his confidences had abruptly ceased—when I had half fancied that some obscure telepathic wave of Asenath’s mental force was intervening to keep him silent. This, though, was something altogether different—and, I felt, infinitely more horrible. The face beside me was twisted almost unrecognisably for a moment, while through the whole body there passed a shivering motion—as if all the bones, organs, muscles, nerves, and glands were readjusting themselves to a radically different posture, set of stresses, and general personality.
     Just where the supreme horror lay, I could not for my life tell; yet there swept over me such a swamping wave of sickness and repulsion—such a freezing, petrifying sense of utter alienage and abnormality—that my grasp of the wheel grew feeble and uncertain. The figure beside me seemed less like a lifelong friend than like some monstrous intrusion from outer space—some damnable, utterly accursed focus of unknown and malign cosmic forces.
...

“I hope you’ll forget my attack back there, Upton,” he was saying. “You know what my nerves are, and I guess you can excuse such things. I’m enormously grateful, of course, for this lift home.
     “And you must forget, too, any crazy things I may have been saying about my wife—and about things in general. That’s what comes from overstudy in a field like mine. My philosophy is full of bizarre concepts, and when the mind gets worn out it cooks up all sorts of imaginary concrete applications. I shall take a rest from now on—you probably won’t see me for some time, and you needn’t blame Asenath for it.
...

“I suppose you think I’m crazy, Dan—but Arkham history ought to hint at things that back up what I’ve told you—and what I’m going to tell you. You’ve seen one of the changes, too—in your car after I told you about Asenath that day coming home from Maine. That was when she got me—drove me out of my body. The last thing of the ride I remember was when I was all worked up trying to tell you what that she-devil is. Then she got me, and in a flash I was back at the house—in the library where those damned servants had me locked up—and in that cursed fiend’s body . . . that isn’t even human. . . . You know, it was she you must have ridden home with . . . that preying wolf in my body. . . . You ought to have known the difference!”
