I shuddered. Then I remembered Preston's warning and the part I had to play. Up to the present, Gastrell suspected nothingof that I felt positive; but let the least suspicion creep into his brain that I was not the man he believed he had been speaking to

Instantly I pulled myself together. For Dulcie's sake even more than for my own I must exercise the utmost care. Her life as well as mine might depend upon the skill and tact I must exercise during the next few hours, possibly during the next few days. I felt I would at that moment have given much to be able to look into the future and know for certain what was going to happen to me, and, most of all, to Dulcie, before I returned to England.

Well it was for my peace of mind that that wish could not be gratified.

On board the boat, rather to my surprise in view of what had happened and of what Gastrell had just said to me, I saw nothing of Gastrell or of any of his companions, including Preston. Apparently one and all must have gone to their cabins immediately upon coming on board.

It was a perfect night in the Channel. Stars and moon shone brightly, and a streak of light stretched away across the smooth water until it touched the sky Hue far out in the darkness. For a long time I stood on deck, abaft the funnel, smoking a cigar, and thinking deeply. I had turned for a moment, for no particular reason, when I thought I saw a shadow pass across the deck, then vanish. I saw it again; and then again. Stepping away from where I stood, hidden by a life-boat, I distinctly discerned three figures moving noiselessly along the deck, going from me. Curiosity prompted me to follow them, and to my surprise I saw them disappear one after another down the hatchway leading to the steerage. As they must, I felt certain, have come out through the saloon door, this rather puzzled me.

It was past midnight when, at last, I went below. The saloon, smoking-room and alleyways were deserted and almost in darkness. No sound of any sort was audible but the rhythmic throbbing of the engines. The boat still travelled without the slightest motion.

Hark!

I stopped abruptly, for I had heard a soundit had sounded like a gasp. Hardly breathing, I listened intently. Again I heard itthis time more faintly. It had seemed to come from a cabin on my left, a little further forward.

I stood quite still in the alleyway for several minutes. Then, hearing nothing more, I went on to my own cabin.

But somehow, try as I would, I could not get to sleep. For hours I lay wide awake upon my bunk. What had caused that curious sound, I kept wondering, though I tried to put the thought from me. And who had those men been, those three silent figures passing like spectres along the deck, and what had they been doing, and why had they gone down into the steerage?
