“It seemed almost too good to be true. I wondered if there was a trap—if the stones were so contrived as to tip over when a weight was placed on them; but I tried a good many with my own weight and with my stick, and all seemed, and actually were, perfectly firm. Of course, I resolved that Brown and I would make an experiment that very night. “I was well prepared. Knowing the sort of place I should have to explore, I had brought a sufficiency of good rope and bands of webbing to surround my body, and cross-bars to hold to, as well as lanterns and candles and crowbars, all of which would go into a single carpet-bag and excite no suspicion. I satisfied myself that my rope would be long enough, and that the wheel for the bucket was in good working order, and then we went home to dinner. “I had a little cautious conversation with the landlord, and made out that he would not be overmuch surprised if I went out for a stroll with my man about nine o’clock, to make (Heaven forgive me!) a sketch of the abbey by moonlight. I asked no questions about the well, and am not likely to do so now. I fancy I know as much about it as anyone in Steinfeld: at least”—with a strong shudder—“I don’t want to know any more. “Now we come to the crisis, and, though I hate to think of it, I feel sure, Gregory, that it will be better for me in all ways to recall it just as it happened. We started, Brown and I, at about nine with our bag, and attracted no attention; for we managed to slip out at the hinder end of the inn-yard into an alley which brought us quite to the edge of the village. In five minutes we were at the well, and for some little time we sat on the edge of the well-head to make sure that no one was stirring or spying on us. All we heard was some horses cropping grass out of sight farther down the eastern slope. We were perfectly unobserved, and had plenty of light from the gorgeous full moon to allow us to get the rope properly fitted over the wheel. Then I secured the band round my body beneath the arms. We attached the end of the rope very securely to a ring in the stonework. Brown took the lighted lantern and followed me; I had a crowbar. And so we began to descend cautiously, feeling every step before we set foot on it, and scanning the walls in search of any marked stone. “Half aloud I counted the steps as we went down, and we got as far as the thirty-eighth before I noted anything at all irregular in the surface of the masonry. Even here there was no mark, and I began to feel very blank, and to wonder if the Abbot’s cryptogram could possibly be an elaborate hoax. At the forty-ninth step the staircase ceased. It was with a very sinking heart that I began retracing my steps, and when I was back on the thirty-eighth—Brown, with the lantern, being a step or two above me—I scrutinized the little bit of irregularity in the stonework with all my might; but there was no vestige of a mark.
