I wiped away the bloody froth that oozed from the gaping mouth, and tried to compose decently the contorted figure. I covered the face. Then I started on my last mission, for now I knew the door. I had bought the knowledge dearly, and I meant to use it for my own purpose, careless of what violence might be necessary to accomplish my end.

When I entered Brande's state-room I found the electric light full on. He was seated at a writing-table with his head resting on his arms, which hung crossways over the desk. The sleeper breathed so deeply it was evident that the effect of the morphia was still strong upon him. One hand clutched a folded parchment. His fingers clasped it nervelessly, and I had only to force them open one by one in order to withdraw the manuscript. As I did this, he moaned and moved in his chair. I had no fear of his awaking. My hand shook as I unfolded the parchment which I unconsciously handled as carefully as though the thing itself were as deadly as the destruction which might be wrought by its direction.

To me the whole document was a mass of unintelligible formulæ. My rusty university education could make nothing of it. But I could not waste time in trying to solve the puzzle, for I did not know what moment some other visitor might arrive to see how Brande fared. I first examined with a pocket microscope the ink of the manuscript, and then making a scratch with Brande's pen on a page of my note-book, I compared the two. The colours were identical. It was the same ink.

In several places where a narrow space had been left vacant, I put 1 in front of the figures which followed. I had no reason for making this particular alteration, save that the figure 1 is more easily forged than any other, and the forgery is consequently more difficult to detect. My additions, when the ink was dry, could only have been discovered by one who was informed that the document had been tampered with. It was probable that a drawer which stood open with the keys in the lock was the place where Brande kept this paper; where he would look for it on awaking. I locked it in the drawer and put the keys into his pocket.

There was something still to do with the sleeping man, whose brain compassed such marvellous powers. His telepathic faculty must be destroyed. I must keep him seriously ill, without killing him. As long as he remained alive his friends would never question his calculations, and the fiasco which was possible under any circumstances would then be assured. I had with me an Eastern drug, which I had bought from an Indian fakir once in Murzapoor. The man was an impostor, whose tricks did not impose on me. But the drug, however he came by it, was reliable. It was a poison which produced a mild form of cerebritis that dulled but did not deaden the mental powers. It acted almost identically whether administered sub-cutaneously or, of course in a larger dose, internally. I brought it home with the intention of giving it to a friend who was interested in vivisection. I did not think that I myself should be the first and last to experiment with it. It served my purpose well.

The moment I pricked his skin, Brande moved in his seat. My hand was on his throat. He nestled his head down again upon his arms, and drew a deep breath. Had he moved again that breath would have been his last. I had been so wrought upon by what I had already done that night, I would have taken his life without the slightest hesitation, if the sacrifice seemed necessary.

When my operation was over, I left the room and moved silently along the corridor till I came to the ladder leading to the deck. Edith Metford was waiting for me as we had arranged. She was shivering in spite of the awful heat.

"Have you done it?" she whispered.

"I have," I answered, without saying how much I had done. "Now you must retire—and rest easy. The formula won't work. I have put both it and Brande himself out of gear."

"Thank God!" she gasped, and then a sudden faintness came over her. It passed quickly, and as soon as she was sufficiently restored, I begged her to go below. She pleaded that she could not sleep, and asked me to remain with her upon the deck. "It would be absurd to suppose that either of us could sleep this night," she very truly said. On which I was obliged to tell her plainly that she must go below. I had more to do.
