"This puzzle _is_ a puzzle." I held the box first to one ear, then to the other. I gave it several sharp raps with my knuckles. There was not an answering sound, not even the sort of reverberation which Pugh and I had noticed at first. It seemed hollower than ever. It was as though the soul of the box was dead. "I suppose if I put you down, and extinguish the gas and return to bed, in about half an hour or so, just as I am dropping off to sleep, the performance will be recommenced. Perhaps the third time will be lucky." But I was mistaken--there was no third time. When I returned to bed that time I returned to sleep, and I was allowed to sleep; there was no continuation of the performance, at least so far as I know. For no sooner was I once more between the sheets than I was seized with an irresistible drowsiness, a drowsiness which so mastered me that I--I imagine it must have been instantly--sank into slumber which lasted till long after day had dawned. Whether or not any more mysterious sounds issued from the bowels of Pugh's puzzle is more than I can tell. If they did, they did not succeed in rousing me. And yet, when at last I did awake, I had a sort of consciousness that my waking had been caused by something strange. What it was I could not surmise. My own impression was that I had been awakened by the touch of a person's hand. But that impression must have been a mistaken one, because, as I could easily see by looking round the room, there was no one in the room to touch me. It was broad daylight. I looked at my watch; it was nearly eleven o'clock. I am a pretty late sleeper as a rule, but I do not usually sleep as late as that. That scoundrel Bob would let me sleep all day without thinking it necessary to call me. I was just about to spring out of bed with the intention of ringing the bell so that I might give Bob a piece of my mind for allowing me to sleep so late, when my glance fell on the dressing-table on which, the night before, I had placed Pugh's puzzle. It had gone! Its absence so took me by surprise that I ran to the table. It _had_ gone. But it had not gone far; it had gone to pieces! There were the pieces lying where the box had been. The puzzle had solved itself. The box was open, open with a vengeance, one might say. Like that unfortunate Humpty Dumpty, who, so the chroniclers tell us, sat on a wall, surely "all the king's horses and all the king's men" never could put Pugh's puzzle together again! The marquetry had resolved itself into its component parts. How those parts had ever been joined was a mystery. They had been laid upon no foundation, as is the case with ordinary inlaid work. The several pieces of wood were not only of different shapes and sizes, but they were as thin as the thinnest veneer; yet the box had been formed by simply joining them together. The man who made that box must have been possessed of ingenuity worthy of a better cause.
