"No; a lower!"

"A lower! What do you mean?"

"I mean that I have merely paralysed your brain--that for many months to come it will not be restored to its normal power--that it will never reach its normal power again unless I choose."

"Then all is lost--lost--lost!" he wailed out. "The end is as far off, and the journey as long, and the way as hard, as if I had never striven.

And the tribute of human tears will be exacted to the uttermost. My life has been in vain!"

The absolute agony in his voice, the note of almost superhuman suffering and despair, was so intense, that, without thinking of what it was this man was grieving over, I found myself saying soothingly:

"No, no! Nothing is lost. It is only your own overstrained nervous system which sends these fantastic nightmares to your brain. I will soon make you all right if you will listen to reason."

He turned to me with the most appealing look which I had ever seen in human eyes save once before--when Natalie pleaded with me.

"I had forgotten," he said, "the issue now lies in your hands. Choose rightly. Choose mercy."

"I will," I answered shortly, for his request brought me back with a jerk to his motive.

"Then you will get me well as soon as your skill can do it?"

"I will keep you in your present condition until I have your most solemn a.s.surance that you will neither go farther yourself nor instigate others to go farther with this preposterous scheme of yours."

"Bah!" Brande e.j.a.c.u.l.a.t.ed contemptuously, and lay back with a sudden content. "My brain is certainly out of order, else I should not have forgotten--until your words recalled it--the Labrador expedition."

"The Labrador expedition?"

"Yes. On the day we sailed for the Arafura Sea, Grey started with another party for Labrador. If we fail to act before the 31st December, in the year 1900, he will proceed. And the end of the century will be the date of the end of the earth. I will signal to him now."

His face changed suddenly. For a moment I thought he was dead. Then the dreadful fact came home to me. He was telegraphing telepathically to Grey. So the murder that was upon my soul had been done in vain. Then another life must be taken. Better a double crime than one resultless tragedy. I was spared this.

Brande opened his eyes wearily, and sighed as if fatigued. The effort, short as it was, must have been intense. He was prostrated. His voice was low, almost a whisper, as he said:

"You have succeeded beyond belief. I cannot even signal him, much less exchange ideas." With that he turned his face from me, and instantly fell into a deep sleep.

I left the cabin and went on deck. As usual, it was fairly sprinkled over with the pa.s.sengers, but owing to the strong head-wind caused by the speed of the steamer, there was a little nook in the bow where there was no one to trouble me with unwelcome company.

I sat down on an arm of the starboard anchor and tried to think. The game which seemed so nearly won had all to be played over again from the first move. If I had killed Brande--which surely would have been justifiable--the other expedition would go on from where he left off.

And how should I find them? And who would believe my story when I got back to England?

Brande must go on. His attempt to wreck the earth, even if the power he claimed were not overrated, would fail. For if the compounds of a common explosive must be so nicely balanced as they require to be, surely the addition of the figures which I had made in his formula would upset the balance of const.i.tuents in an agent so delicate, though so powerful, as that which he had invented. When the master failed, it was more than probable that the pupil would distrust the invention, and return to London for fresh experiments. Then a clean sweep must be made of the whole party. Meantime, it was plain that Brande must be allowed the opportunity of failing. And this it would be my hazardous duty to superintend.

I returned to Brande's cabin with my mind made up. He was awake, and looked at me eagerly, but waited for me to speak. Our conversation was brief, for I had little sympathy with my patient, and the only anxiety I experienced about his health was the hope that he would not die until he had served my purpose.

"I have decided to get you up," I said curtly.

"You have decided well," he answered, with equal coldness.

That was the whole interview--on which so much depended.

After this I did not speak to Brande on any subject but that of his symptoms, and before long he was able to come on deck. The month I spoke of as the duration of his illness was an intentional exaggeration on my part.

Rockingham was forgotten with a suddenness and completeness that was almost ghastly. The Society claimed to have improved the old maxim to speak nothing of the dead save what is good. Of the dead they spoke not at all. It is a callous creed, but in this instance it pleased me well.

We did not touch at Aden, and I was glad of it. The few attractions of the place, the diving boys and the like, may be a relief in ordinary sea voyages, but I was too much absorbed in my experiment on Brande to bear with patience any delay which served to postpone the crisis of my scheme. I had treated him well, so far as his bodily health went, but I deliberately continued to tamper with his brain, so that any return of his telepathic power was thus prevented. Indeed, Brande himself was not anxious for such return. The power was always exercised at an extreme nervous strain, and it was now, he said, unnecessary to his purpose.

In consequence of this determination, I modified the already minute doses of the drug I was giving him. This soon told with advantage on his health. His physical improvement partly restored his confidence in me, so that he followed my instructions faithfully. He evidently recognised that he was in my power; that if I did not choose to restore him fully no other man could.

Of the ship's officers, Anderson, who was in command, and Percival, the doctor, were men of some individuality. The captain was a good sailor and an excellent man of business. In the first capacity, he was firm, exacting, and scrupulously conscientious. In the second, his conscience was more elastic when he saw his way clear to his own advantage. He had certain rigid rules of conduct which he prided himself on observing to the letter, without for a moment suspecting that their _raison d'etre_ lay in his own interests. His commercial morality only required him to keep within the law. His final contract with myself was, I admit, faithfully carried out, but the terms of it would not have discredited the most predatory business man in London town.

Percival was the opposite pole of such a character. He was a clever man, who might have risen in his profession but for his easy-going indolence.

I spent many an hour in his cabin. He was a sportsman and a skilled _raconteur_. His anecdotes helped to while the weary time away. He exaggerated persistently, but this did not disturb me. Besides, if in his narratives he lengthened out the hunt a dozen miles and increased the weight of the fish to an impossible figure, made the brace a dozen and the ten-ton boat a man-of-war, it was not because he was deliberately untruthful. He looked back on his feats through the telescope of a strongly magnifying memory. It was more agreeable to me to hear him boast his prowess than have him inquire after the health and treatment of my patient Brande. On this matter he was naturally very curious, and I very reticent.

That Brande did not entirely trust me was evident from his confusion when I surprised him once reading his formula. His anxiety to convince me that it was only a commonplace memorandum was almost ludicrous. I was glad to see him anxious about that doc.u.ment. The more carefully he preserved it, and the more faithfully he adhered to its conditions, the better for my experiment. A sense of security followed this incident. It did not last long. It ended that evening.

After a day of almost unendurable heat, I went on deck for a breath of air. We were well out in the Indian Ocean, and soundings were being attempted by some of our naturalists. I sat alone and watched the sun sink down into the gla.s.sy ocean on which our rushing vessel was the only thing that moved. As the darkness of that hot, still night gathered, weird gleams of phosphorus broke from the steamer's bows and streamed away behind us in long lines of flashing spangles. Where the swell caused by the pa.s.sage of the ship rose in curling waves, these, as they splashed into mimic breakers, burst into showers of flamboyant light.

The water from the discharge-pipe poured down in a cascade, that shone like silver. Every turn of the screw dashed a thousand flashes on either side, and the heaving of the lead was like the flight of a meteor, as it plunged with a luminous trail far down into the dark unfathomable depths below.

My name was spoken softly. Natalie Brande stood beside me. The spell was complete. The unearthly glamour of the magical scene had been compa.s.sed by her. She had called it forth and could disperse it by an effort of her will. I wrenched my mind free from the foolish phantasmagoria.

"I have good news," Natalie said in a low voice. Her tones were soft, musical; her manner caressing. Happiness was in her whole bearing, tenderness in her eyes. Dread oppressed me. "Herbert is now well again."

"He has been well for some time," I said, my heart beating fast.

"He is not thoroughly restored even yet. But this evening he was able to receive a message from me by the thought waves. He thinks you are plotting injury to him. His brain is not yet sufficiently strong to show how foolish this fugitive fancy is. Perhaps you would go to him. He is troubling himself over this. You can set his mind at rest."

"I can--and will--if I am not too late," I answered.

CHAPTER XVI.

5000 TO DETAIN THE SHIP.

Brande was asleep when I entered his cabin. His writing-table was covered with sc.r.a.ps of paper on which he had been scribbling. My name was on every sc.r.a.p, 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 pa.s.sed. 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 pa.s.sed, 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 sh.o.r.e. 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--"
