couldn’t afford to waste the time, in the first place. Each case removed meant another journey to and from the vessel, and you were waiting above for his measurements. Then he was probably doubtful as to weight. Too much at once wouldn’t easily be drawn up, and might upset a small boat.
“Well, so much for the white stone. But there was more; close by the stone I noticed (although I think you didn’t) a mark in the claystone. It was a triangular depression or pit, sharp at the bottom — just the hole that would be made by the sharp impact of the square corner of a heavy box, if shod with iron, as the bullion cases are. This was one important thing. It seemed to indicate that the boxes had not been lifted directly up from the seabed, but had been dragged sideways — at all events at first — so that a sharp corner had turned over and dug into the claystone! I walked a little farther and found more indications — slight scratches, small stones displaced, and so on, that convinced me of this, and also pointed out the direction in which the cases had been dragged. I followed the direction, and presently arrived at another stone, rather smaller than the clean one. The cases had evidently caught against this, and it had been displaced by their momentum, and perhaps by a possible wrench from above. The green growth covered the part which had been exposed to the water, and the rest of the stone fitted the hole beside it, from which it had been pulled. Clearly these things were done recently, or the sea would have wiped out all the traces in the soft claystone. The rest of what I did under water of course you understood.”
“I suppose so: you took the bearings of the two stones in relation to the ship by pacing the distances.”
“That is so. I kept the figures in my head till I could make a note of them, as you saw, on paper. The rest was mere calculation. What I judged had happened was this. Gullen had arranged with somebody, identity unknown, but certainly somebody with a boat at his disposal, to lay the line, and take it up the following night. Now anything larger than a rowing boat could not have got up quite so close to you in the night (although your tug was at the other end of the wreck) without a risk of being seen. But no rowing boat could have dragged those cases forcibly along the bottom; they would act as an anchor to it. Therefore this was what had happened. The thieves had come in a large boat — a fishing smack, lugger, or something of that sort — with a small boat in tow. The sailing boat had lain to at a convenient distance, in the direction in which it was afterwards to go, so as to save time if observed, and a man had put off quietly in the small boat to pick up the float, whatever it was. There must have been a lot of slack line on this for the purpose, as also for the purpose of allowing the float to drift about fairly freely, and not attract attention by remaining in one place. The man pulled off to the sailing boat, and took the float and line aboard. Then the sailing boat swung off in the direction of home, and the line was hauled in with the plunder at the end of it.”
“One would think you had seen it all — or done it,” Merrick remarked, with a laugh.
“Nothing else could have happened, you see. That chain of events is the only one that will explain the circumstances. A rapid grasp of the whole circumstances and a perfect appreciation of each is more than half the battle in such work as this. Well, you know I got the exact bearings of the wreck on the chart, worked out from that the lay of the two stones with the scratch marks between, and then it was obvious that a straight line drawn through these and carried ahead would indicate, approximately, at any rate, the direction the thieves’ vessel had taken. The line fell on the coast close by the village of Lostella — indeed that was the only village for some few miles either way. The indication was not certain, but it was likely, and the only one available, therefore it must be followed up.”
“And what about the painted hatch? How did you guess that?”
“Well, I saw there were hatch-gratings belonging to the Nicobar floating about, and it seemed probable that the thieves would use for a float something similar to the other wreckage in the vicinity, so as not to attract attention. Nothing would be more likely than a hatch-grating. But then, in small vessels, such as fishing-luggers and so on, fittings are almost always painted — they can’t afford to be such holystoning swells as those on the Nicobar. So I judged the grating might be painted, and this would possibly have been noticed by some sharp person. I made the shot, and hit. The boy remembered the white grating, which had gone — ‘ washed away,’ as he thought. That was useful to me, as you shall see.
“I made off toward Lostella. The tide was low and it was getting dusk when I arrived. A number of boats and smacks were lying anchored on the beach, but there were few people to be seen. I began looking out for smacks with white-painted fittings in them. There are not so many of these among fishing vessels — brown or red is more likely, or sheer colourless dirt over paint unrecognisable. There were only two that I saw last night. The first might have been the one I wanted, but there was nothing to show it. The second was the one. She was half-decked and had a small white-painted hatch. I shifted the hatch and found a long line, attached to the grating at one end and carrying a hook at the other! They had neglected to unfasten their apparatus — perhaps had an idea that there might be a chance of using it again in a few days. I went to the transom and read the inscription, ‘ Rebecca. Peter and David Garthew, Lostella.’ Then my business was to find the Garthews.
“I wandered about the village for some little time, and presently got hold of a boy. I made a simple excuse for asking about the Garthews — wanted to go for a sail to-morrow. The boy, with many grins, confided to me that both of the Garthews were ‘ on the booze.’ I should find them at the Smack Inn, where they had been all day, drunk as fiddlers. This seemed a likely sort of thing after the haul they had made. I went to the Smack Inn, determined to claim old friendship with the Garthews, although I didn’t know Peter from David. There they were — one sleepy drunk, and the other loving and crying drunk. I got as friendly as possible with them under the circumstances, and at closing time stood another gallon of beer and carried it home for them, while they carried each other. I took cafe to have a good look round in the cottage. I even helped Peter’s ‘ old woman ‘ — the lady with the broom — to carry them up to bed. But nowhere could I see anything that looked like a bullion-case or a hiding-place for one. So I came away, determined to renew my acquaintance in the morning, and to carry it on as long as might be necessary; also to look at the garden in the daylight for signs of burying. With that view I fixed that little gimlet in my walking-stick, as you saw.
“This morning I was at Lostella before ten, and took a look at the Garthews’ cabbages. It seemed odd that half a dozen, all in a clump together, looked withered and limp, as though they had been dug up hastily, the roots broken, perhaps, and then replanted. And altogether these particular cabbages had a dissipated, leaning-different-ways look, as though they had been on the loose with the Garthews. So, seeing a grubby child near the back door of the cottage, I went towards him, walking rather unsteadily, so as, if I were observed, to favour the delusion that I was not yet quite got over last night’s diversions. ‘ Hullo, my b-boy,’ I said, ‘hullo, li’l b-boy, look here,’ and I plunged my hand into my trousers’ pocket and brought it out full of small change. Then, making a great business of selecting him a penny, I managed to spill it all over the dissipated cabbages. It was easy then, in stooping to pick up the change, to lean heavily on my stick and drive it through the loose earth. As I had expected, there was a box below. So I gouged away with my walking-stick while I collected my coppers, and finally swaggered off, after a few civil words with the ‘ old woman,’ carrying with me evident proof that it was white wood recently buried there. The rest you saw for yourself. I think you and I may congratulate each other on having dodged that broom. It hit all the others.”
“What I’m wild about,” said Merrick, “is having let that scoundrel Gullen get off. He’s an artful chap, without a doubt. He saw us go over the side, you know, and after you had gone he came into the cabin for some instructions. Your pencil notes and the chart were on the table, and no doubt he put two and two together (which was more than I could, not knowing what had happened), and concluded to make himself safe for a bit. He had no leave that night — he just pulled away on the quiet. Why didn’t you give me the tip to keep him?”
“That wouldn’t have done. In the first place, there was no legal evidence to warrant his arrest, and ordering him to keep
