"A fine old musty smell, that's what first struck me," he said afterward. "The dust of ages; cobwebs galore. Only one window, looking seaward, and that shut fast. 'Twas stifling to a fellow used to the fresh air. There was a ramshackle old bedstead in one corner; a four-poster, with a canopy and crimson hangings; at least, they had been crimson; the dust was so thick on 'em that I couldn't see what the color was till I'd rubbed a bit of it off. That was where the old eccentric breathed his last, I suppose; and no one thought it worth carting away. In the middle of the room was a deal table and a chair with a broken back; not another stick of furniture.
"But in the corner near the window I saw something that told a tale—a pile of kegs, almost reaching to the low roof. 'Empty or full?' thought I. I lifted one; it was full. I knew they weren't old Congleton's property, or they'd have disappeared with the rest of his furniture. How did I know he had any? Why, because I noticed nails on the wall, where pictures had hung, and a clean patch on one of the walls—cleaner than the rest, that is—where a bureau or something of the sort had stood. Besides, no man who'd have a mahogany bedstead and hangings that once were splendid would have been likely to be satisfied with a deal table and a common rickety chair. They were the kind of things you'd expect in a plowman's or a fisherman's kitchen.
"At any rate, I saw that somebody had used the room since Congleton departed this life, for there were some crumbs on the table, and a chipped tumbler that smelt uncommonly like the kegs. Ghosts don't eat bread and cheese and drink spirits! And there was a coil of rope under the table, and by the window a cheap sort of curtain that just fitted. I held it up to see; right in the middle of it was a round hole. And when I came to look at the bed I saw that the mattress had a big dent in it, and no dust on it. Somebody had had a nap there since old Congleton died.
"Of course I saw all this in a very few seconds. Then I went on the prowl. I pulled out the bedstead; by George! didn't it creak! I thought the old thing would fall to pieces. Behind it was a cupboard, and in the cupboard a large bull's-eye lantern, and a long cylinder of cardboard about eighteen inches long. 'What's that for?' I thought. It didn't strike me at the moment, but I took the things out and put them on the table. The lamp leaked a little; I found I'd got some spots of oil on my breeches.
"When I put them on the table I noticed something I'd missed before. In the middle was a sort of pattern in red chalk—a circle with a tail to it; and at the edge of the table two parallel strokes. They'd been done some time, for the marks in the middle were almost hidden by oil stains. Those stains puzzled me for a bit. I could have understood wine stains better. But at last I tumbled to it. That was the place where the lamp was put for the signaling. I set it down on the circular mark; it just fitted. But I could not make out at first what the two straight strokes at the edge were for. Then I caught sight of the roll of cardboard and another idea struck me. I lifted it and stuck it on the bull's-eye; it fitted like a glove; and when I turned the lantern so that the handle was over the tail of the circle I found that the cylinder just reached to the two marks.
"But that only puzzled me more than ever, for the lantern and cylinder were now pointing straight at old Congleton's bed. Would you believe it?—I didn't at first think of turning the table round! Of course it wasn't a fixture, and when I did think of it I saw through the whole scheme. Turned round, the lantern pointed through the window. The cylinder was a clever notion. It would prevent the light from the bull's-eye spreading, so that while it would be seen a good distance out at sea, it wouldn't attract notice in the neighborhood, except that a faint glow might be seen from below. But the Folly wasn't in sight from the village, and there'd be precious few of the ordinary country folk who'd care to be near the spot after dark. They'd be in mortal fear of seeing old Congleton's ghost.
"I was still a little puzzled. What need was there to mark the place of the lantern so exactly. Anywhere near the window the light would be seen clearly enough out at sea. But now that I had moved the table I noticed four red marks on the floor. 'Here's another discovery,' I thought; 'there's a mark for each leg of the table.' I slewed it around again, so that the legs stood on the marks. Then it flashed on me; if the table was always in the same place, and the lantern always exactly on the marks, the light would always hit the same point out at sea. 'A very pretty scheme!' says I to myself. 'Good master smugglers have all their wits about 'em.'
"It was clear as daylight now that the Folly was a signal-station, and sometimes, as the kegs showed, a storehouse as well. Of course they used old Congleton's machinery for hoisting the kegs. That coil of rope, now! I pulled it over, and there, just underneath, was a pulley—an iron bar fitted with a small grooved wheel, and resting at each end on a wooden block; little grooves had been chiseled out to keep the bar steady. And when I came to look at 'em I saw, as I might have expected, that they'd been oiled not long before.
"By this time I'd found out all I wished to know. The only thing left to be discovered was, who used the Folly? I made up my mind to get Lieutenant Blake to let me bring some men to the place one night when we saw the light, and catch the men in the act. But before I went away I thought I'd go down the staircase and see if there was anything there. I couldn't find a door, yet the staircase must lead direct into the room; there was no other. I had another look at the cupboard, and found after some trouble that half the back of it was movable—it was a sliding panel. I pulled it aside; it moved quite easily; and I stepped through—carefully, I can tell you, for it was pitch dark.
"I got on to the staircase, and went down gingerly, a step at a time. It was wooden, and the stairs were pretty rotten; they creaked as I moved, and I clung on to a rope that made a sort of hand-rail, afraid of pitching head first to the bottom. It smelled very close, and I took some time to go down, for the stairs were narrow, and as it was a winding staircase they scarcely gave foothold except at the wall end. At last I got to the bottom, and then I saw a glint or two of light coming through chinks in the doorway.
