After some talk, I went forward and told the carpenter to step aft and bore a hole in the bulkhead that separated the Major’s berth from mine. He took the necessary tools from his chest and followed me. The captain was now again on deck, talking with the Major; in fact, detaining him in conversation, as had been preconcerted. I went into the Major’s berth, and quickly settled upon a spot for an eye-hole. The carpenter then went to work in my cabin, and in a few minutes bored an orifice large enough to enable me to command a large portion of the adjacent interior. I swept the sawdust from the deck in the Major’s berth, so that no hint should draw his attention to the hole, which was pierced in a corner shadowed by a shelf. I then told the carpenter to manufacture a plug and paint its extremity of the colour of the bulkhead. He brought me this plug in a quarter of an hour. It fitted nicely, and was to be withdrawn and inserted as noiselessly as though greased.

I don’t want you to suppose this Peeping-Tom scheme was at all to my taste, albeit my own proposal; but the truth is, the Major’s telling us that some one had stolen his diamond made all who lived aft hotly eager to find out whether he spoke the truth or not; for, if he had been really robbed of the stone, then suspicion properly rested upon the officers and the steward, which was an infernal consideration: dishonouring and inflaming enough to drive one to seek a remedy in even a baser device than that of secretly keeping watch on a man in his bedroom. Then, again, the captain told me that the Major, whilst they talked when the carpenter was at work making the hole, had said he would give notice of his loss to the police at Capetown (at which place we were to touch), and declared he’d take care no man went ashore—from Captain North himself down to the youngest apprentice—till every individual, every sea-chest, every locker, drawer, shelf and box, bunk, bracket and crevice, had been searched by qualified rummagers.

On this the day of the theft, nothing more was said about the diamond: that is, after the captain had emphatically informed Major Hood that he meant to take no steps whatever in the matter. I had expected to find the Major sullen and silent at dinner; he was not, indeed, so talkative as usual, but no man watching and hearing him would have supposed so heavy a loss as that of a stone worth fifteen thousand pounds, the gift of an Eastern potentate to the Queen of England, was weighing upon his spirits.

It is with reluctance I tell you that, after dinner that day, when he went to his cabin, I softly withdrew the plug and watched him. I blushed whilst thus acting, yet I was determined, for my own sake and for the sake of my shipmates, to persevere. I spied nothing noticeable saving this: he sat in a folding chair and smoked, but every now and again he withdrew his cigar from his mouth and talked to it with a singular smile. It was a smile of cunning, that worked like some baleful, magical spirit in the fine high breeding of his features; changing his looks just as a painter of incomparable skill might colour a noble, familiar face into a diabolical expression, amazing those who knew it only in its honest and manly beauty. I had never seen that wild, grinning countenance on him before, and it was rendered the more remarkable by the movement of his lips whilst he talked to himself, but inaudibly.

A week slipped by. Time after time I had the man under observation; often when I had charge of the deck I’d leave the captain to keep a look-out, and steal below and watch Major Hood in his cabin.

It was a Sunday, I remember. I was lying in my bunk half dozing—we were then, I think, about a three-weeks’ sail from Table Bay—when I heard the Major go to his cabin. I was already sick of my aimless prying; and whilst I now lay I thought to myself, “I’ll sleep; what is the good of this trouble? I know exactly what I shall see. He is either in his chair, or his bunk, or overhauling his clothes, or standing, cigar in mouth, at the open porthole.” And then I said to myself, “If I don’t look now I shall miss the only opportunity of detection that may occur.” One is often urged by a sort of instinct in these matters.

I got up, almost as through an impulse of habit, noiselessly withdrew the plug, and looked. The Major was at that instant standing with a pistol-case in his hand: he opened it as my sight went to him, took out one of a brace of very elegant pistols, put down the case, and on his apparently touching a spring in the butt of the pistol, the silver plate that ornamented the extremity sprang open as the lid of a snuff-box would, and something small and bright dropped into his hand. This he examined with the peculiar cunning smile I have before described; but, owing to the position of his hand, I could not see what he held, though I had not the least doubt that it was the diamond.

I watched him breathlessly. After a few minutes he dropped the stone into the hollow butt-end, shut the silver plate, shook the weapon against his ear as though it pleased him to rattle the stone, then put it in its case, and the case into a portmanteau.
