“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. 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 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.

Towards midnight our talk of London died away, and we stood side by side leaning over the bulwarks and staring dreamily over the silent, starlit sea, each pursuing his own thoughts. It was the atmosphere for sentiment, and I began upon my gratitude.

“If I may say it,” said I, after a time, “you have saved my life.”

“Chance,” he answered. “Just chance.”

“I prefer to make my thanks to the accessible agent.”

“Thank no one. You had the need, and I had the knowledge; and I injected and fed you much as I might have collected a specimen. I was bored and wanted something to do. If I’d been jaded that day, or hadn’t liked your face, well — it’s a curious question where you would have been now!”

This damped my mood a little. “At any rate,” I began.

“It’s chance, I tell you,” he interrupted, “as everything is in a man’s life. Only the asses won’t see it! Why am I here now, an outcast from civilisation, instead of being a happy man enjoying all the pleasures of London? Simply because eleven years ago — I lost my head for ten minutes on a foggy night.”

He stopped. “Yes?” said I.

“That’s all.”

We relapsed into silence. Presently he laughed. “There’s something in this starlight that loosens one’s tongue. I’m an ass, and yet somehow I would like to tell you.”

“Whatever you tell me, you may rely upon my keeping to myself — if that’s it.”

He was on the point of beginning, and then shook his head, doubtfully.

“Don’t,” said I. “It is all the same to me. After all, it is better to keep your secret. There’s nothing gained but a little relief if I respect your confidence. If I don’t — well?”

He grunted undecidedly. I felt I had him at a disadvantage, had caught him in the mood of indiscretion; and to tell the truth I was not curious to learn what might have driven a young medical student out of London. I have an imagination. I shrugged my shoulders and turned away. Over the taffrail leant a silent black figure, watching the stars. It was Montgomery’s strange attendant. It looked over its shoulder quickly with my movement, then looked away again.

It may seem a little thing to you, perhaps, but it came like a sudden blow to me. The only light near us was a lantern at the wheel. The creature’s face was turned for one brief instant out of the dimness of the stern towards this illumination, and I saw that the eyes that glanced at me shone with a pale-green light. I did not know then that a reddish luminosity, at least, is not uncommon in human eyes. The thing came to me as stark inhumanity. That black figure with its eyes of fire struck down through all my adult thoughts and feelings, and for a moment the forgotten horrors of childhood came back to my mind. Then the effect passed as it had come. An uncouth black figure of a man, a figure of no particular import, hung over the taffrail against the starlight, and I found Montgomery was speaking to me.
