Brande was asleep when I entered his cabin. His writing-table was covered with scraps of paper on which he had been scribbling. My name was on every scrap, preceded or followed by an unfinished sentence, thus: "Marcel is thinking— When I was ill, Marcel thought— Marcel means to—" All these I gathered up carefully and put in my pocket. Then I inoculated him with as strong a solution of the drug I was using on him as was compatible with the safety of his life. Immediate danger being thus averted, I determined to run no similar risk again.

For many days after this our voyage was monotonous. The deadly secret shared by Edith Metford and myself drew us gradually nearer to each other as time passed. She understood me, or, at least, gave me the impression that she understood me. Little by little that capricious mood which I have heretofore described changed into one of enduring sympathy. With one trivial exception, this lasted until the end. But for her help my mind would hardly have stood the strain of events which were now at hand, whose livid shadows were projected in the rising fire of Brande's relentless eyes.

Brande appeared to lose interest gradually in his ship's company. He became daily more and more absorbed in his own thoughts. Natalie was ever gentle, even tender. But I chafed at the impalpable barrier which was always between us. Sometimes I thought that she would willingly have ranged herself on my side. Some hidden power held her back. As to the others, I began to like the boy Halley. He was lovable, if not athletic. His devotion to Natalie, which never waned, did not now trouble me. It was only a friendship, and I welcomed it. Had it been anything more, it was not likely that he would have prevailed against the will of a man who had done murder for his mistress. We steamed through the Malay Archipelago, steering north, south, east, west, as if at haphazard, until only the navigating officers and the director of the Society knew how our course lay. We were searching for an island about the bearings of which, it transpired, some mistake had been made. I do not know whether the great laureate ever sailed these seas. But I know that his glorious islands of flowers and islands of fruit, with all their luscious imagery, were here eclipsed by our own islands of foliage. The long lagoons, the deep blue bays, the glittering parti-coloured fish that swam in visible shoals deep down amidst the submerged coral groves over which we passed, the rich-toned sea-weeds and brilliant anemones, the yellow strands and the steep cliffs, the riotous foliage that swept down from the sky to the blue of the sea; all these natural beauties seemed to cry to me with living voices—to me bound on a cruise of universal death.

After a long spell of apparently aimless but glorious steaming, a small island was sighted on our port bow. The Esmeralda was steered directly for it, and we dropped anchor in a deep natural harbour on its southern shore. Preparations for landing had been going on during the day, and everything was ready for quitting the ship.

It was here that my first opportunity for making use of the gold I had brought with me occurred. Anderson was called up by Brande, who made him a short complimentary speech, and finished it by ordering his officer to return to England, where further instructions would be given him. This order was received in respectful silence. Captain Anderson had been too liberally treated to demur if the Esmeralda had been ordered to the South Pole.

Brande went below for a few minutes, and as soon as he had disappeared I went forward to Anderson and hailed him nervously, for there was not a moment to spare.

"Anderson," I said hurriedly, "you must have noticed that Mr. Brande is an eccentric—"

"Pardon me, sir; it is not my business to comment upon my owner."

"I did not ask you to comment upon him, sir," I said sharply. "It is I who shall comment upon him, and it is for you to say whether you will undertake to earn my money by waiting in this harbour till I am ready to sail back with you to England."

"Have you anything more to say, sir?" Anderson asked stiffly.

"I presume I have said enough."

"If you have nothing more to say I must ask you to leave the bridge, and if it were not that you are leaving the ship this moment, I would caution you not to be impertinent to me again."

He blew his whistle, and a steward ran forward.

"Johnson, see Mr. Marcel's luggage over the side at once." To me he said shortly: "Quit my ship, sir."

This trivial show of temper, which, indeed, had been provoked by my own hasty speech, turned my impatience into fury.

"Before I quit your ship," I said, with emphasis, "I will tell you how you yourself will quit it. You will do so between two policemen if you land in England, and between two marines if you think of keeping on the high seas. Before we started, I sent a detailed statement of this ship, the nature of this nefarious voyage, and the names of the passengers—or as many as I knew—to a friend who will put it in proper hands if anything befalls me. Go back without me and explain the loss of that French fishing fleet which was sunk the very night we sailed. It is an awkward coincidence to be explained by a man who returns from an unknown voyage having lost his entire list of passengers. You cannot be aware of what this man Brande intends, or you would at least stand by us as long as your own safety permitted. In any case you cannot safely return without us."

Anderson, after reflecting for a moment, apologised for his peremptory words, and agreed to stand by night and day, with fires banked, until I, and all whom I could prevail upon to return with me, got back to his vessel. There was no danger of his running short of coal. A ship that was practically an ocean liner in coal ballast would be a considerable time in burning out her own cargo. But he insisted on a large money payment in advance. I had foolishly mentioned that I had a little over £5000 in gold. This he claimed on the plea that "in duty to himself"—a favourite phrase of his—he could not accept less. But I think his sense of duty was limited only by the fact that I had hardly another penny in the world. Under the circumstances he might have waived all remuneration. As he was firm, and as I had no time to haggle, I agreed to give him the money. Our bargain was only completed when Brande returned to the deck.

It was strange that on an island like that on which we were landing there should be a regular army of natives waiting to assist us with our baggage, and the saddled horses which were in readiness were out of place in a primeval wilderness. An Englishman came forward, and, saluting Brande, said all was ready for the start to the hills. This explained the puzzle. An advance agent had made everything comfortable. For Brande, his sister, and Miss Metford the best appointed horses were selected. I, as physician to the chief, had one. The main body had to make the journey on foot, which they did by very easy stages, owing to the heat and the primitive track which formed the only road. Their journey was not very long—perhaps ten miles in a direct line.

Mounted as we were, it was often necessary to stoop to escape the dense masses of parasitic growth which hung in green festoons from every branch of the trees on either side. Under this thick shade all the riotous vegetation of the tropics had fought for life and struggled for light and air till the wealth of their luxuriant death had carpeted the underwood with a thick deposit of steaming foliage. As we ascended the height, every mile in distance brought changes in the botanical growths, which might have passed unnoticed by the ordinary observer or ignorant pioneer. All were noted and commented on by Brande, whose eye was still as keen as his brain had once been brilliant. His usual staid demeanour changed suddenly. He romped ahead of us like a schoolboy out for a holiday. Unlike a schoolboy, however, he was always seeking new items of knowledge and conveying them to us with unaffected pleasure. He was more like a master who had found new ground and new material for his class. Natalie gave herself up like him to this enjoyment of the moment. Edith Metford and I partly caught the glamour of their infectious good-humour. But with both of us it was tempered by the knowledge of what was in store.

When we arrived at our destination we dismounted, at Brande's request, and tied our horses to convenient branches. He went forward, and, pushing aside the underwood with both hands, motioned to us to follow him till he stopped on a ledge of rock which overtopped a hollow in the mountain. The gorge below was the most beautiful glade I ever looked upon.

It was a paradise of foliage. Here and there a fallen tree had formed a picturesque bridge over the mountain stream which meandered through it. Far down below there was a waterfall, where gorgeous tree-ferns rose in natural bowers, while others further still leant over the lotus-covered stream, their giant leaves trailing in the slow-moving current. Tangled masses of bracken rioted in wild abundance over a velvety green sod, overshadowed by waving magnolias. Through the trees bright-plumaged birds were flitting from branch to branch in songless flight, flashing their brilliant colours through the sunny leaves. In places the water splashed over moss-grown rocks into deep pools. Every drifting spray of cloud threw over the dell a new light, deepening the shadows under the great ferns.

It was here in this glorious fairyland; here upon this island, where before us no white foot had ever trod; whose nameless people represented the simplest types of human existence, that Herbert Brande was to put his devilish experiment to the proof. I marvelled that he should have selected so fair a spot for so terrible a purpose. But the papers which I found later amongst the man's effects on the Esmeralda explain much that was then incomprehensible to me.

Our camp was quickly formed, and our life was outwardly as happy as if we had been an ordinary company of tourists. I say outwardly, because, while we walked and climbed and collected specimens of botanical or geological interest, there remained that latent dread which always followed us, and dominated the most frivolous of our people, on all of whom a new solemnity had fallen. For myself, the fact that the hour of trial for my own experiment was daily drawing closer and more inevitable, was sufficient to account for my constant and extreme anxiety.

Brande joined none of our excursions. He was always at work in his improvised laboratory. The boxes of material which had been brought from the ship nearly filled it from floor to roof, and from the speed with which these were emptied, it was evident that their contents had been systematised before shipment. In place of the varied collection of substances there grew up within the room a cone of compound matter in which all were blended. This cone was smaller, Brande admitted, than what he had intended. The supply of subordinate fulminates, though several times greater than what was required, proved to be considerably short. But as he had allowed himself a large margin—everything being on a scale far exceeding the minimum which his calculations had pointed to as sufficient—this deficiency did not cause him more than a temporary annoyance. So he worked on.

When we had been three weeks on the island I found the suspense greater than I could bear. The crisis was at hand, and my heart failed me. I determined to make a last appeal to Natalie, to fly with me to the ship. Edith Metford would accompany us. The rest might take the risk to which they had consented.

I found Natalie standing on the high rock whence the most lovely view of the dell could be obtained, and as I approached her silently she was not aware of my presence until I laid my hand on her shoulder.

"Natalie," I said wistfully, for the girl's eyes were full of tears, "do you mind if I withdraw now from this enterprise, in which I cannot be of the slightest use, and of which I most heartily disapprove?"

"The Society would not allow you to withdraw. You cannot do so without its permission, and hope to live within a thousand miles of it," she answered gravely.

"I should not care to live within ten thousand miles of it. I should try to get and keep the earth's diameter between myself and it."

She looked up with an expression of such pain that my heart smote me. "How about me? I cannot live without you now," she said softly.

"Don't live without me. Come with me. Get rid of this infamous association of lunatics, whose object they themselves cannot really appreciate, and whose means are murder—"

But there she stopped me. "My brother could find me out at the uttermost ends of the earth if I forsook him, and you know I do not mean to forsake him. For yourself—do not try to desert. It would make no difference. Do not believe that any consideration would cause me willingly to give you a moment's pain, or that I should shrink from sacrificing myself to save you." With one of her small white hands she gently pressed my head towards her. Her lips touched my forehead, and she whispered: "Do not leave me. It will soon be over now. I—I—need you."

As I was returning dejected after my fruitless appeal to Natalie, I met Edith Metford, to whom I had unhappily mentioned my proposal for an escape.

"Is it arranged? When do we start?" she asked eagerly.

"It is not arranged, and we do not start," I answered in despair.

"You told me you would go with her or without her," she cried passionately. "It is shameful—unmanly."

"It is certainly both if I really said what you tell me. I was not myself at the moment, and my tongue must have slandered me. I stay to the end. But you will go. Captain Anderson will receive you—"

"How am I to be certain of that?"

"I paid him for your passage, and have his receipt."

"And you really think I would go and leave—leave—"

"Natalie? I think you would be perfectly justified."

At this the girl stamped her foot passionately on the ground and burst into tears. Nor would she permit any of the slight caresses I offered. I thought her old caprices were returning. She flung my arm rudely from her and left me bewildered.
