"Another illustration of the old saying that the unexpected always happens," I replied.

"If we are fortunate enough to see our friends again, we shall have some extraordinary stories to tell," said the Commander-in-Chief. "The question is, however, shall we ever see them again?"

"That remains to be proved," I answered. "We must put our wits to work to see what can be done."

The words had scarcely left my lips, before young Reiffenburg appeared upon the scene and abruptly informed us that our promenade was at an end, and that it behoved us to return to our cabins, in order that our companions, who had just finished their meal, might take our places. We followed his instructions, and made our way slowly to the saloon below, half hoping that we should have a chance of exchanging a few words with our friends. They were not there, however, having been ordered to their cabins so that we should not meet. There was nothing for it, therefore, but to bid each other good-night, and to retire to our respective state-rooms with as good grace as possible.

Next morning, after breakfast, we were allowed on deck again for an hour, also after luncheon, and again in the evening. During the progress of the latter meal I was struck by the expression on the Commander-in-Chief's face. It was as if he were suffering from a severe attack of suppressed excitement. He fidgeted uneasily in his seat, and seemed to experience great difficulty in eating the food set before him. This excitement found vent while we were in the companion ladder on our way to the deck above. Half-way up he took me by the arm and said in a hoarse whisper—

"My God! Manderville, quite by chance to-day, I have discovered the most diabolical plot ever hatched by mortal man."

"Then be careful," I returned, "that they do not suspect you of knowing it. Wait until we are safely out of ear-shot before you say anything to me on the subject."

When we reached the deck we found the sentry on guard as usual. We accordingly walked aft, and had paced the poop two or three times before I would permit the Commander-in-Chief to unfold his tale. Then leaning upon the taffrail, and looking at the white streak of our wake, I asked him what he had discovered.

"The most villainous plot, imaginable," he replied. "You will remember that Reiffenburg left the saloon before we had finished luncheon this afternoon, and that I was the first to go up on deck. You will also recall the fact that the fellow with the rifle kept close to us while we were on deck, so that it was impossible for me to tell you what I had heard. On reaching the top of the companion, I found Reiffenburg and the dark man who acts as steward, and yet who seems to be on such familiar terms with them, in close conversation beside the door."
