Her manner was so straightforward and honest that I could not bring myself to believe in her duplicity; yet—Thinking to surprise her into a betrayal of her guilt, I blurted out: “The chronometer and sextant were both destroyed last night; there is a traitor among us.” But she never turned a hair by way of evidencing guilty knowledge of the catastrophe. “Who could it have been?” she cried. “The Germans would be crazy to do it, for their lives are as much at stake as ours.” “Men are often glad to die for an ideal—an ideal of patriotism, perhaps,” I replied; “and a willingness to martyr themselves includes a willingness to sacrifice others, even those who love them. Women are much the same, except that they will go even further than most men—they will sacrifice everything, even honor, for love.” I watched her face carefully as I spoke, and I thought that I detected a very faint flush mounting her cheek. Seeing an opening and an advantage, I sought to follow it up. “Take von Schoenvorts, for instance,” I continued: “he would doubtless be glad to die and take us all with him, could he prevent in no other way the falling of his vessel into enemy hands. He would sacrifice anyone, even you; and if you still love him, you might be his ready tool. Do you understand me?” She looked at me in wide-eyed consternation for a moment, and then she went very white and rose from her seat. “I do,” she replied, and turning her back upon me, she walked quickly toward her room. I started to follow, for even believing what I did, I was sorry that I had hurt her. I reached the door to the crew’s room just behind her and in time to see von Schoenvorts lean forward and whisper something to her as she passed; but she must have guessed that she might be watched, for she passed on. That afternoon it clouded over; the wind mounted to a gale, and the sea rose until the craft was wallowing and rolling frightfully. Nearly everyone aboard was sick; the air became foul and oppressive. For twenty-four hours I did not leave my post in the conning tower, as both Olson and Bradley were sick. Finally I found that I must get a little rest, and so I looked about for some one to relieve me. Benson volunteered. He had not been sick, and assured me that he was a former R.N. man and had been detailed for submarine duty for over two years. I was glad that it was he, for I had considerable confidence in his loyalty, and so it was with a feeling of security that I went below and lay down.
