As has been mentioned, the door was constructed of timber very much resembling oak, and its inner surface was reinforced by stout iron straps some three or four inches wide, at least half an inch thick, and extending across the whole width of the door. The round heads of bolts studded at intervals along the whole length of the straps indicated that similar iron bands existed on the other side of the door, and that the straps, inside and outside—of which there were no less than seven pairs—were connected together, thus clearly indicating the immense strength of the door. It was thus hopeless to think of cutting a way out through it; the only manner in which it could be passed was by opening it in the usual manner.
Frobisher therefore set to work to examine the lock, to discover whether there existed any possibility of picking it. It was an old-fashioned piece of mechanism, and, luckily, the iron case was on the inside of the door, the great keyhole being placed near the centre. Now for a piece of stout wire, the stouter the better! The young Englishman proceeded at once to hunt about among the various machines and instruments in the dim corners of the chamber in search of what he required. For some time he was unsuccessful, and he had reluctantly arrived at the conclusion that the search must end in failure, when his eyes happened to fall upon the very thing he needed.
Standing at the far end of the apartment, in that part of it enclosed by the circular portion of wall, was a sinister-looking machine, and to the gearing of one of its handles was attached a short piece of iron rod which he thought he might disengage without much difficulty. Forthwith he applied himself to the task, with such success that, half an hour later, he found himself in possession of what he required. True, it was somewhat stouter than it should have been for his purpose, but this was one of those occasions upon which he found his exceptional strength very useful, and after a few experiments he succeeded in bending it to the shape he wanted.
He was experimenting with the bent rod in the lock when, fortunately, his quick ear caught the sound of footsteps hurrying down the stone-flagged corridor toward his cell.
Snatching the wire out of the lock, he hastily dropped it into the nearest available place of concealment, and sauntered toward the opposite side of the chamber. There would be no time, he knew, to take down and redistribute the pile of articles he had used to enable him to look out of the window, so he was compelled to leave them as they were, trusting that, in the dim light, the visitor, whoever he might be, would not particularly notice the arrangement. A moment later there was a sound of keys rattling outside, the lock clicked loudly, and the door opened and closed behind a man carrying a lamp, which he set down on the floor just inside the room, after carefully locking the door again.
The thought instantly flashed through Frobisher’s mind that perhaps after all there would be no need for him to go on with the manufacture of his skeleton key; for was not the actual key of the door in the room at that very moment? True, it was in the possession of another man; but unless he happened to possess fire-arms, it would be queer indeed if a desperate prisoner could not overpower him, tie him up somehow, and secure the key to obtain his liberty. Frobisher’s eyes glistened at the thought, and his muscles braced themselves for a spring. But at the critical moment the idea occurred to him that the other was in his power anyhow, and that he could secure the key later on, just as well as now; and that, meanwhile, before he acted hastily, it might be well to hear whether the fellow had anything to say. Perhaps this was an official come to set him at liberty, or perhaps— Well, he would wait a little, at all events, and see what developments ensued.
Having locked the door and pocketed the key, the visitor picked up the lantern and advanced into the room, holding the light high and glancing keenly round until his eyes fell upon Frobisher, whereupon he gave a short grunt of satisfaction and hung the lantern on a convenient peg.
By the additional light thus afforded, the Englishman was able to examine his visitor more closely, and to estimate his chances of success if things came to a rough-and-tumble fight for possession of the key.
The stranger was tall, almost as tall as Frobisher himself, but not nearly so heavily built, and appeared to be about fifty-five to sixty years of age, so that the young Englishman did not anticipate any serious difficulty in mastering him. He was very richly dressed in garments of fine silk, elaborately decorated with embroidery, and wore round his neck a heavy gold chain, the centre of which was studded with a single enormous ruby. As a head-covering he wore a round Chinese cap, which was ornamented by a single magnificent peacock’s feather, fastened to the cap by a brooch of solid gold set with another huge ruby.
The man’s whole appearance was indeed imposing and magnificent in the extreme, and Frobisher instantly guessed that he was in the presence of a very important official indeed. This man, he told himself, could surely not be a Korean. No Korean ever attained to such a commanding stature, no Korean had ever been known to display so haughty a bearing, so dominant a personality; and as his eyes slowly travelled from the details of the man’s costume to his face, the prisoner recognised that his visitor was indeed not a Korean, but a Chinaman, and a Chinaman of the highest grade, too—without doubt, a mandarin. There was no mistaking the thin, ascetic, high-bred face, the prominent cheek-bones, the almond-shaped eyes; and the long but scanty moustache scarcely concealed a strong, resolute-looking mouth, the lips of which were, however, rather too thin, lending an expression of cruelty and relentlessness of purpose which was anything but reassuring to the prisoner.
