“Confident as I am that you will not trifle with this appeal, my heart sinks and my hand trembles at the bare thought of such a possibility. Think of me at this hour, in a strange place, labouring under a blackness of distress that no fancy can exaggerate, and yet well aware that, if you will but punctually serve me, my troubles will roll away like a story that is told. Serve me, my dear Lanyon, and save

“Your friend,

“H. J.”

“P. S. I had already sealed this up when a fresh terror struck upon my soul. It is possible that the post-office may fail me, and this letter not come into your hands until to-morrow morning. In that case, dear Lanyon, do my errand when it shall be most convenient for you in the course of the day; and once more expect my messenger at midnight. It may then already be too late; and if that night passes without event, you will know that you have seen the last of Henry Jekyll.”

Upon the reading of this letter, I made sure my colleague was insane; but till that was proved beyond the possibility of doubt, I felt bound to do as he requested. The less I understood of this farrago, the less I was in a position to judge of its importance; and an appeal so worded could not be set aside without a grave responsibility. I rose accordingly from table, got into a hansom, and drove straight to Jekyll’s house. The butler was awaiting my arrival; he had received by the same post as mine a registered letter of instruction, and had sent at once for a locksmith and a carpenter. The tradesmen came while we were yet yet speaking; and we moved in a body to old Dr. Denman’s surgical theatre, from which (as you are doubtless aware) Jekyll’s private cabinet is most conveniently entered. The door was very strong, the lock excellent; the carpenter avowed he would have great trouble and have to do much damage, if force were to be used; and the locksmith was near despair. But this last was a handy fellow, and after two hours’ work, the door stood open. The press marked E was unlocked; and I took out the drawer, had it filled up with straw and tied in a sheet, and returned with it to Cavendish Square.

Here I proceeded to examine its contents. The powders were neatly enough made up, but not with the nicety of the dispensing chemist; so that it was plain they were of Jekyll’s private manufacture; and when I opened one of the wrappers I found what seemed to me a simple crystalline salt of a white colour. The phial, to which I next turned my attention, might have been about half-full of a blood-red liquor, which was highly pungent to the sense of smell and seemed to me to contain phosphorus and some volatile ether. At the other ingredients I could make no guess. The book was an ordinary version-book and contained little but a series of dates. These covered a period of many years, but I observed that the entries ceased nearly a year ago and quite abruptly. Here and there a brief remark was appended to a date, usually no more than a single word: “double” occurring perhaps six times in a total of several hundred entries; and once very early in the list and followed by several marks of exclamation, “total failure!!!” All this, though it whetted my curiosity, told me little that was definite. Here were a phial of some tincture, a paper of some salt, and the record of a series of experiments that had led (like too many of Jekyll’s investigations) to no end of practical usefulness. How could the presence of these articles in my house affect either the honour, the sanity, or the life of my flighty colleague? If his messenger could go to one place, why could he not go to another? And even granting some impediment, why was this gentleman to be received by me in secret? The more I reflected the more convinced I grew that I was dealing with a case of cerebral disease: and though I dismissed my servants to bed, I loaded an old revolver, that I might be found in some posture of self-defence.

I looked round for some weapon. Nothing. Then with an inspiration I turned over the deck chair, put my foot on the side of it, and tore away the side rail. It happened that a nail came away with the wood, and projecting, gave a touch of danger to an otherwise petty weapon. I heard a step outside, and incontinently flung open the door and found Montgomery within a yard of it. He meant to lock the outer door! I raised this nailed stick of mine and cut at his face; but he sprang back. I hesitated a moment, then turned and fled, round the corner of the house. “Prendick, man!” I heard his astonished cry, “don’t be a silly ass, man!”

Another minute, thought I, and he would have had me locked in, and as ready as a hospital rabbit for my fate. He emerged behind the corner, for I heard him shout, “Prendick!” Then he began to run after me, shouting things as he ran. This time running blindly, I went northeastward in a direction at right angles to my previous expedition. Once, as I went running headlong up the beach, I glanced over my shoulder and saw his attendant with him. I ran furiously up the slope, over it, then turning eastward along a rocky valley fringed on either side with jungle I ran for perhaps a mile altogether, my chest straining, my heart beating in my ears; and then hearing nothing of Montgomery or his man, and feeling upon the verge of exhaustion, I doubled sharply back towards the beach as I judged, and lay down in the shelter of a canebrake. There I remained for a long time, too fearful to move, and indeed too fearful even to plan a course of action. The wild scene about me lay sleeping silently under the sun, and the only sound near me was the thin hum of some small gnats that had discovered me. Presently I became aware of a drowsy breathing sound, the soughing of the sea upon the beach.

After about an hour I heard Montgomery shouting my name, far away to the north. That set me thinking of my plan of action. As I interpreted it then, this island was inhabited only by these two vivisectors and their animalised victims. Some of these no doubt they could press into their service against me if need arose. I knew both Moreau and Montgomery carried revolvers; and, save for a feeble bar of deal spiked with a small nail, the merest mockery of a mace, I was unarmed.

So I lay still there, until I began to think of food and drink; and at that thought the real hopelessness of my position came home to me. I knew no way of getting anything to eat. I was too ignorant of botany to discover any resort of root or fruit that might lie about me; I had no means of trapping the few rabbits upon the island. It grew blanker the more I turned the prospect over. At last in the desperation of my position, my mind turned to the animal men I had encountered. I tried to find some hope in what I remembered of them. In turn I recalled each one I had seen, and tried to draw some augury of assistance from my memory.

Then suddenly I heard a staghound bay, and at that realised a new danger. I took little time to think, or they would have caught me then, but snatching up my nailed stick, rushed headlong from my hiding-place towards the sound of the sea. I remember a growth of thorny plants, with spines that stabbed like pen-knives. I emerged bleeding and with torn clothes upon the lip of a long creek opening northward. I went straight into the water without a minute’s hesitation, wading up the creek, and presently finding myself kneedeep in a little stream. I scrambled out at last on the westward bank, and with my heart beating loudly in my ears, crept into a tangle of ferns to await the issue. I heard the dog (there was only one) draw nearer, and yelp when it came to the thorns. Then I heard no more, and presently began to think I had escaped.
