"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 passengers, 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 constituents 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.
