“It is as simple as knocking a beef yearling in the head with a stone,” I admitted, nettled that I could contrive nothing subtler. “We find our boat, beg, buy or steal it, and place it as near at hand as may be convenient. That done, we lay hands on Sir Judas, sleeping or waking, and then for the river and a long pull with the tide or against it, as fortune chances to smile or frown upon us in fixing the hour.” “Aye,” said Champe, quite without enthusiasm, “it’s surely simple enough, Captain Dick.” “Think of a better, then,” I snapped curtly. The sergeant let me have another sight of his ferocious grin. “I’ve had my turn of thinking, and it’s you for it now,” he retorted. “I might say that you put your foot squarely into my think-trap and stopped it from going off, but I shan’t. You’ll give the order, Captain Dick, and I’ll obey it, if it tells me to cut Mr. Benedict Iscariot’s throat while he is asleep.” After that we were silent for a time, both of us weighing and measuring the hazards of the desperate game, I think. Champe still kept his place on the floor, sitting jack-knifed with his hands locked over his knees and his wide-opened eyes staring at nothing. Suddenly, as I was opening my mouth to ask where we were likely to find our boat, he laid a hand on my knee and shook his head. “What is it?” I asked, but only with my eyes. “There is some one stirring in the room beyond,” he said in a half-whisper. “Who is your neighbor, Captain Dick?” Matching his tone, I said that I knew none of my fellow lodgers save Lieutenant Castner, and that I did not know the placing of the lieutenant’s room. “We were full careless,” said my companion. And then he got upon his feet with no more noise than a cat would have made and suddenly extinguished the candle. The firelight still flung long shadows about the room, and in the shelter of the broadest of them Champe glided away to the wall of suspicion and examined it foot by foot with scrutinizing eyes and gently gliding finger-tips. When he crept back to me he was holding out a forefinger the end of which was whitened with powdered lime. “That tells the tale,” he whispered. “There’s a whiff of this dust on the floor, and above it, at the height of a man’s head, a peep-hole the size of a goose-quill. We must know who is in that room, Captain Dick.” Here was a crude peril at the very outset of things; but what the sergeant said was very true. We must know who our spy was at all costs. Taking off our shoes we passed silently into the corridor and found the neighboring door by feeling cautiously for it in the dark. It was on the latch, and after listening breathlessly for a full minute we opened the door by slow inchings and listened again. Still there was no sound, and now we entered the room, groping blindly, first for impeding obstacles and then for the bed where our spy might be feigning sleep.
