“I could not believe it,” I said; “and yet two of my men reported having seen you in conversation with von Schoenvorts late at night upon two separate occasions—after each of which some great damage was found done us in the morning. I didn’t want to doubt you; but I carried all the responsibility of the lives of these men, of the safety of the ship, of your life and mine. I had to watch you, and I had to put you on your guard against a repetition of your madness.” She was looking at me now with those great eyes of hers, very wide and round. “Who told you that I spoke with Baron von Schoenvorts at night, or any other time?” she asked. “I cannot tell you, Lys,” I replied, “but it came to me from two different sources.” “Then two men have lied,” she asserted without heat. “I have not spoken to Baron von Schoenvorts other than in your presence when first we came aboard the _U_-33. And please, when you address me, remember that to others than my intimates I am Miss La Rue.” Did you ever get slapped in the face when you least expected it? No? Well, then you do not know how I felt at that moment. I could feel the hot, red flush surging up my neck, across my cheeks, over my ears, clear to my scalp. And it made me love her all the more; it made me swear inwardly a thousand solemn oaths that I would win her. Chapter 4 For several days things went along in about the same course. I took our position every morning with my crude sextant; but the results were always most unsatisfactory. They always showed a considerable westing when I knew that we had been sailing due north. I blamed my crude instrument, and kept on. Then one afternoon the girl came to me. “Pardon me,” she said, “but were I you, I should watch this man Benson—especially when he is in charge.” I asked her what she meant, thinking I could see the influence of von Schoenvorts raising a suspicion against one of my most trusted men. “If you will note the boat’s course a half-hour after Benson goes on duty,” she said, “you will know what I mean, and you will understand why he prefers a night watch. Possibly, too, you will understand some other things that have taken place aboard.” Then she went back to her room, thus ending the conversation. I waited until half an hour after Benson had gone on duty, and then I went on deck, passing through the conning-tower where Benson sat, and looking at the compass. It showed that our course was north by west—that is, one point west of north, which was, for our assumed position, about right. I was greatly relieved to find that nothing was wrong, for the girl’s words had caused me considerable apprehension. I was about to return to my room when a thought occurred to me that again caused me to change my mind—and, incidentally, came near proving my death-warrant.
