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
