“All set?” I asked him.
“Sure, Mike. Go ahead and shoot.”
I had found the exact range that would involve all of Halpin’s body without affecting the chair itself. Fixing my gaze upon him, I pressed the little knob that turned on the current of vibratory rays. The result was practically instantaneous, for he seemed to melt like a puff of thinning smoke. I could still see his outlines for a moment, and the look of a phantasmal astonishment on his face. And then he was gone—utterly gone.
Perhaps it will be a source of wonderment that, having annihilated Halpin as far as all earthly existence was concerned, I was not content merely to leave him in the unseen, intangible plane to which he had been transposed. Would that I had been content to do so. But the wrong I had suffered was hot and cankerous within me, and I could not bear to think that he still lived, in any form or upon any plane. Nothing but absolute death would suffice to assuage my resentment; and the death must be inflicted by my own hand. It now remained to follow Halpin into that realm which no man had ever visited before, and of whose geographical conditions and characteristics I had formed no idea whatever. I felt sure, however, that I could enter it and return safely, after disposing of my victim. The return of the cat left no apparent room for doubt on that score.
I turned out the lights; and seating myself in the chair with the portable infra-red vibrator in my arms, I switched on the ultra-violet power. The sensation I felt was that of one who falls with nightmare velocity into a great gulf. My ears were deaf with the intolerable thunder of my descent, a frightful sickness overcame me, and I was near to losing all consciousness for a moment, in the black vortex of roaring space and force that seemed to draw me nadir-ward through the ultimate pits. Then the speed of my fall was gradually retarded, and I came gently down to something that was solid beneath my feet. There was a dim glimmering of light that grew stronger as my eyes accustomed themselves to it, and by this light I saw Halpin standing a few feet away. Behind him were dark, amorphous rocks and the vague outlines of a desolate landscape of low mounds and primordial treeless flats. Even though I had hardly known what to expect, I was somewhat surprised by the character of the environment in which I found myself. At a guess, I would have said that the fourth dimension would be something more colorous and complex and varied—a land of multifold hues and many-angled forms. However, in its drear and primitive desolation, the place was truly ideal for the commission of the act I had intended.
Halpin came toward me in the doubtful light. There was a dazed and almost idiotic look on his face, and he stuttered a little as he tried to speak.
“W-what h-happened?” he articulated at last.
“Never mind what happened. It isn’t a circumstance to what’s going to happen now.”
I laid the portable vibrator aside on the ground as I spoke.
The dazed look was still on Halpin’s face when I drew the hunting-knife and stabbed him through the body with one clean thrust. In that thrust, all the stifled hatred, all the cankering resentment of ten insufferable years was finally vindicated. He fell in a twisted heap, twitched a little, and lay still. The blood oozed very slowly from his side and formed a puddle. I remember wondering at its slowness, even then, for the oozing seemed to go on through hours and days.
Somehow, as I stood there, I was obsessed by a feeling of utter unreality. No doubt the long strain I had been under, the daily stress of indurate emotions and decade-deferred hopes, had left me unable to realize the final consummation of my desire when it came. The whole thing seemed no more than one of the homicidal day-dreams in which I had imagined myself stabbing Halpin to the heart and seeing his hateful body lie before me.
At length, I decided that it was time to effect my return; for surely nothing could be gained by lingering any longer beside Halpin’s corpse amid the unutterable dreariness of the fourth-dimensional landscape. I erected the vibrator in a position where its rays could be turned upon myself, and pressed the switch.
I was aware of a sudden vertigo, and felt that I was about to begin another descent into fathomless vortical gulfs. But, though the vertigo persisted, nothing happened, and I found that I was still standing beside the corpse, in the same dismal milieu.
Dumbfoundment and growing consternation crept over me. Apparently, for some unknown reason, the vibrator would not work in the way I had so confidently expected. Perhaps, in these new surroundings, there was some barrier to the full development of the infra-red power. I do not know; but, at any rate, there I was, in a truly singular and far from agreeable predicament.
I do not know how long I fooled in a mounting frenzy with the mechanism of the vibrator, in the hope that something had temporarily gone wrong and could be remedied, if the difficulty were only found. However, all my tinkerings were of no avail: the machine was in perfect working-order, but the required force was wanting. I tried the experiment of exposing small articles to the influence of the rays. A silver coin and a handkerchief dissolved and disappeared very slowly, and I felt that they must have regained the levels of mundane existence. But evidently the vibrational force was not strong enough to transport a human being.
Finally I gave it up and threw the vibrator to the ground. In the surge of a violent despair that came upon me, I felt the need of muscular action, of prolonged movement; and I started off at once to explore the weird realm in which I had involuntarily imprisoned myself.
It was an unearthly land—a land such as might have existed before the creation of life. There were undulating blanks of desolation beneath the uniform grey of a heaven without moon or sun or stars or clouds, from which an uncertain and diffused glimmering was cast upon the world beneath. There were no shadows, for the light seemed to emanate from all directions. The soil was a grey dust in places and a grey viscidity of slime in others; and the low mounds I have already mentioned were like the backs of prehistoric monsters heaving from the primal ooze. There were no signs of insect or animal life, there were no trees, no herbs, and not even a blade of grass, a patch of moss or lichen, or a trace of algae. Many rocks were strewn chaotically through the desolation; and their forms were such as an idiotic demon might have devised in aping the handiwork of God. The light was so dim that all things were lost at a little distance; and I could not tell whether the horizon was near or far.
It seems to me that I must have wandered on for several hours, maintaining as direct a course of progression as I could. I had a compass—a thing that I always carry with me; but it refused to function, and I was driven to conclude that there were no magnetic poles in this new world.
Suddenly, as I rounded a pile of the vast amorphous boulders, I came to a human body that lay huddled on the ground, and saw incredulously that it was Halpin. The blood still oozed from the fabric of his coat, and the pool it had formed was no larger than when I had begun my journey.
I felt sure that I had not wandered in a circle, as people are said to do amid unfamiliar surroundings. How, then, could I have returned to the scene of my crime? The problem nearly drove me mad as I pondered it; and I set off with frantic vigor in an opposite direction from the one I had first taken.
For all intents and purposes, the scene through which I now passed was identical with the one that lay on the other side of Halpin’s corpse. It was hard to believe that the low mounds, the drear levels of dust and ooze and the monstrous boulders, were not the same as those among which I had made my former way. As I went, I took out my watch with the idea of timing my progress; but the hands had stopped at the very moment when I had taken my plunge into unknown space from the laboratory; and though I wound it carefully, it refused to run again.
