Those were anxious days, during which I had but little opportunity to associate with Lys. I had given her the commander's room, Bradley and I taking that of the deck-officer, while Olson and two of our best men occupied the room ordinarily allotted to petty officers. I made Nobs' bed down in Lys' room, for I knew she would feel less alone.
Nothing of much moment occurred for a while after we left British waters behind us. We ran steadily along upon the surface, making good time. The first two boats we sighted made off as fast as they could go; and the third, a huge freighter, fired on us, forcing us to submerge. It was after this that our troubles commenced. One of the Diesel engines broke down in the morning, and while we were working on it, the forward port diving-tank commenced to fill. I was on deck at the time and noted the gradual list. Guessing at once what was happening, I leaped for the hatch and slamming it closed above my head, dropped to the centrale. By this time the craft was going down by the head with a most unpleasant list to port, and I didn't wait to transmit orders to some one else but ran as fast as I could for the valve that let the sea into the forward port diving-tank. It was wide open. To close it and to have the pump started that would empty it were the work of but a minute; but we had had a close call.
I knew that the valve had never opened itself. Some one had opened it—some one who was willing to die himself if he might at the same time encompass the death of all of us.
After that I kept a guard pacing the length of the narrow craft. We worked upon the engine all that day and night and half the following day. Most of the time we drifted idly upon the surface, but toward noon we sighted smoke due west, and having found that only enemies inhabited the world for us, I ordered that the other engine be started so that we could move out of the path of the oncoming steamer. The moment the engine started to turn, however, there was a grinding sound of tortured steel, and when it had been stopped, we found that some one had placed a cold-chisel in one of the gears.
It was another two days before we were ready to limp along, half repaired. The night before the repairs were completed, the sentry came to my room and awoke me. He was rather an intelligent fellow of the English middle class, in whom I had much confidence.
"Well, Wilson," I asked. "What's the matter now?"
He raised his finger to his lips and came closer to me. "I think I've found out who's doin' the mischief," he whispered, and nodded his head toward the girl's room. "I seen her sneakin' from the crew's room just now," he went on. "She'd been in gassin' wit' the boche commander. Benson seen her in there las' night, too, but he never said nothin' till I goes on watch tonight. Benson's sorter slow in the head, an' he never puts two an' two together till some one else has made four out of it."
If the man had come in and struck me suddenly in the face, I could have been no more surprised.
"Say nothing of this to anyone," I ordered. "Keep your eyes and ears open and report every suspicious thing you see or hear."
The man saluted and left me; but for an hour or more I tossed, restless, upon my hard bunk in an agony of jealousy and fear. Finally I fell into a troubled sleep. It was daylight when I awoke. We were steaming along slowly upon the surface, my orders having been to proceed at half speed until we could take an observation and determine our position. The sky had been overcast all the previous day and all night; but as I stepped into the centrale that morning I was delighted to see that the sun was again shining. The spirits of the men seemed improved; everything seemed propitious. I forgot at once the cruel misgivings of the past night as I set to work to take my observations.
