For a time I hurried on hopelessly perplexed, and pursued by that stealthy approach. Whatever it was, the Thing either lacked the courage to attack me, or it was waiting to take me at some disadvantage. I kept studiously to the open. At times I would turn and listen; and presently I had half persuaded myself that my pursuer had abandoned the chase, or was a mere creation of my disordered imagination. Then I heard the sound of the sea. I quickened my footsteps almost into a run, and immediately there was a stumble in my rear.

I turned suddenly, and stared at the uncertain trees behind me. One black shadow seemed to leap into another. I listened, rigid, and heard nothing but the creep of the blood in my ears. I thought that my nerves were unstrung, and that my imagination was tricking me, and turned resolutely towards the sound of the sea again.

In a minute or so the trees grew thinner, and I emerged upon a bare, low headland running out into the sombre water. The night was calm and clear, and the reflection of the growing multitude of the stars shivered in the tranquil heaving of the sea. Some way out, the wash upon an irregular band of reef shone with a pallid light of its own. Westward I saw the zodiacal light mingling with the yellow brilliance of the evening star. The coast fell away from me to the east, and westward it was hidden by the shoulder of the cape. Then I recalled the the fact that Moreau’s beach lay to the west.

A twig snapped behind me, and there was a rustle. I turned, and stood facing the dark trees. I could see nothing — or else I could see too much. Every dark form in the dimness had its ominous quality, its peculiar suggestion of alert watchfulness. So I stood for perhaps a minute, and then, with an eye to the trees still, turned westward to cross the headland; and as I moved, one among the lurking shadows moved to follow me.

My heart beat quickly. Presently the broad sweep of a bay to the westward became visible, and I halted again. The noiseless shadow halted a dozen yards from me. A little point of light shone on the further bend of the curve, and the grey sweep of the sandy beach lay faint under the starlight. Perhaps two miles away was that little point of light. To get to the beach I should have to go through the trees where the shadows lurked, and down a bushy slope.

I could see the Thing rather more distinctly now. It was no animal, for it stood erect. At that I opened my mouth to speak, and found a hoarse phlegm choked my voice. I tried again, and shouted, “Who is there?” There was no answer. I advanced a step. The Thing did not move, only gathered itself together. My foot struck a stone. That gave me an idea. Without taking my eyes off the black form before me, I stooped and picked up this lump of rock; but at my motion the Thing turned abruptly as a dog might have done, and slunk obliquely into the further darkness. Then I recalled a schoolboy expedient against big dogs, and twisted the rock into my handkerchief, and gave this a turn round my wrist. I heard a movement further off among the shadows, as if the Thing was in retreat. Then suddenly my tense excitement gave way; I broke into a profuse perspiration and fell a-trembling, with my adversary routed and this weapon in my hand.

Small indeed was my appetite. This inexplicable incident, this reversal of my previous experience, seemed, like the Babylonian finger on the wall, to be spelling out the letters of my judgment; and I began to reflect more seriously than ever before on the issues and possibilities of my double existence. That part of me which I had the power of projecting, had lately been much exercised and nourished; it had seemed to me of late as though the body of Edward Hyde had grown in stature, as though (when I wore that form) I were conscious of a more generous tide of blood; and I began to spy a danger that, if this were much prolonged, the balance of my nature might be permanently overthrown, the power of voluntary change be forfeited, and the character of Edward Hyde become irrevocably mine. The power of the drug had not been always equally displayed. Once, very early in my career, it had totally failed me; since then I had been obliged on more than one occasion to double, and once, with infinite risk of death, to treble the amount; and these rare uncertainties had cast hitherto the sole shadow on my contentment. Now, however, and in the light of that morning’s accident, I was led to remark that whereas, in the beginning, the difficulty had been to throw off the body of Jekyll, it had of late gradually but decidedly transferred itself to the other side. All things therefore seemed to point to this: that I was slowly losing hold of my original and better self, and becoming slowly incorporated with my second and worse.

Between these two, I now felt I had to choose. My two natures had memory in common, but all other faculties were most unequally shared between them. Jekyll (who was composite) now with the most sensitive apprehensions, now with a greedy gusto, projected and shared in the pleasures and adventures of Hyde; but Hyde was indifferent to Jekyll, or but remembered him as the mountain bandit remembers the cavern in which he conceals himself from pursuit. Jekyll had more than a father’s interest; Hyde had more than a son’s indifference. To cast in my lot with Jekyll, was to die to those appetites which I had long secretly indulged and had of late begun to pamper. To cast it in with Hyde, was to die to a thousand interests and aspirations, and to become, at a blow and for ever, despised and friendless. The bargain might appear unequal; but there was still another consideration in the scales; for while Jekyll would suffer smartingly in the fires of abstinence, Hyde would be not even conscious of all that he had lost. Strange as my circumstances were, the terms of this debate are as old and commonplace as man; much the same inducements and alarms cast the die for any tempted and trembling sinner; and it fell out with me, as it falls with so vast a majority of my fellows, that I chose the better part and was found wanting in the strength to keep to it.

Yes, I preferred the elderly and discontented doctor, surrounded by friends and cherishing honest hopes; and bade a resolute farewell to the liberty, the comparative youth, the light step, leaping impulses and secret pleasures, that I had enjoyed in the disguise of Hyde. I made this choice perhaps with some unconscious reservation, for I neither gave up the house in Soho, nor destroyed the clothes of Edward Hyde, which still lay ready in my cabinet. For two months, however, I was true to my determination; for two months I led a life of such severity as I had never before attained to, and enjoyed the compensations of an approving conscience. But time began at last to obliterate the freshness of my alarm; the praises of conscience began to grow into a thing of course; I began to be tortured with throes and longings, as of Hyde struggling after freedom; and at last, in an hour of moral weakness, I once again compounded and swallowed the transforming draught.
