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. [Illustration: "SOMETHING SMALL AND BRIGHT DROPPED INTO HIS HAND."] 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.
