He had noticed, when taking his precarious walk along the edge of the battlements, that an old rusty iron chain was loosely twisted round the bar which stretched across the diameter of the well, about on a level with where he hung suspended. It might be possible, springing into the air, to catch the end of this chain, which terminated in a ring. He had done that sort of thing more than once in gymnasiums, though under very much more favourable conditions. Even if he succeeded in catching the ring in his flight, he might only find himself in a worse position. The chain might refuse to unwind from the bar, or the whole contrivance, rusted by years of exposure, might snap under his weight. But even if this were so, he reflected, he could but drop to the bottom of the well, which he was bound to do in any event, if he stayed where he was, while every foot that the chain unrolled before breaking was twelve inches less for him to fall. Evidently there was not an instant to lose, for his fingers were already getting stiff and numb with the tension they were undergoing. So, setting his teeth, he sprang into the air, on this last desperate venture. For one horrid second he felt the ring which his fingers touched, slipping through his grasp. Then with one supreme effort, he crooked his hand through it, and swung suspended by one arm. A moment later, he had brought his other hand to his aid. But scarcely had he steadied himself, when the bar, round which the chain was wound, and which evidently worked in a socket, began to revolve. It was rusty and out of gear, and as it let him down, it gave him the most frightful series of jerks, which seemed to dislocate every bone in his body. It would let out three or four feet of chain at lightning speed, and then, catching in its rusty gearings, would stop with a racking jerk, remaining still perhaps a whole minute, before it moved on again, to repeat the operation. Moreover, as he got farther and farther down the well, and there was a greater length of chain above him, it began to oscillate frightfully, twirling him round in one direction till his head swam, and then reversing the operation. All tortures must come to an end, however, and when he was ten feet from the bottom of the well, a corroded link snapped, and he dropped the remaining distance like a log, bringing down thirty feet of iron chain on top of him.
The blow which he received rendered him instantly unconscious, and it was hours later before he came to himself. His first knowledge of the world and things in general was a realisation that in some mysterious way the entire firmament was divided in half by a black band, and it was only as his brain became a little clearer that he realised that he was lying on his back looking up at the rim of the well. He sat up, and examined himself critically. He had evidently cut his head slightly, for it was still bleeding. Moreover, he was black and blue from head to foot, but he was rejoiced to find, after a careful examination, that no bones were broken, nor had he even suffered a sprain, and in a few moments he was able to stand upright.
His position, however, was none the less precarious. The breaking of the chain had ended for ever any chance of his ascending the tower, and he must either effect an entrance through the roof or depend on the very uncertain chance of attracting notice from without, to escape starvation.
Lying face down on the floor of the roof, he tried to look out of the little holes in the mouths of the gargoyles, but could see nothing, and from the appearance of the sky over his head, he judged that it must be growing dark. This reminded him of his bicycle lamp, which a hasty examination proved to be intact, and feeling that he would at least have light for his investigations, was a great source of comfort to him.
His next procedure was to examine the roof. Here, fate once more befriended him, for he very quickly found a trap-door and, moreover, was able to lift it. Looking down he could see nothing but utter darkness. However, this did not deter him, and he hastily made his arrangements for further investigation, first taking the precaution to light a match and drop it into the opening. It fell, about ten or twelve feet, evidently striking the floor and burning there a minute or two before it went out. It revealed nothing but surrounding darkness, but it apprised him of the fact he was most desirous to know, that the atmosphere was not mephitical. He determined, nevertheless, to take his time about descending, and left the trap-door wide open, so that as much fresh air might get in as possible.
In the interval he amused himself by taking off one of his socks and unravelling it as best he could. Weaving a cord with the thread thus obtained, he lowered his bicycle lantern, which he had lighted, into the room below, swinging it gently back and forwards. Its glancing rays told him that the apartment was entirely bare and deserted, and showed him also a narrow wooden ladder, black with age, leading up to the trap-door above which he stood. Drawing up the light, he took it in his hand, and being cautious after his recent experience, reached down and tested each round of the ladder most carefully. To his surprise it held his weight, and a moment later he was on the floor of the secret chamber.
The apartment had no secrets to reveal. It was absolutely bare, and empty of anything except a broken old sconce lying in a corner. The whole room, however, was indescribably dusty and musty, and he was very thankful to push aside a curtain of chain mail and descend the staircase.
At its foot he saw lying the coveted papers. Forgetful of everything else, he sat down upon the lowest step, and by the light of his lantern proceeded to examine them. They more than fulfilled his utmost expectations. There was a complete cipher and its key, a full list of the members of the cabinet who were to pass upon the treaty, with comments on each, and a memorandum of the amounts to be given to certain of them, coupled with suggestions as to the attitude which Darcy should take towards others, together with precise instructions as to the carrying out of the plot; the whole signed by Riddle in the interests of the firm. The evidence was complete, and Stanley gasped as he realised the advantage of this tremendous stroke of luck. One fact which his perusal had elicited caused him to draw a long sigh of relief. Miss Fitzgerald's name was not mentioned in the incriminating document, and so much did he wish to believe her innocent, that in spite of all accumulated evidence, he felt a sense of exultation that he could still, if worst came to worst, shield her from the effects of her own folly. He told himself that he might, after all, prove to the satisfaction of his own conscience that she was innocent of criminal intent. Darcy he would have no mercy for. He must be punished for his crime, and the fact of his being the criminal would give Inez her freedom, and then—— Ah! but if Belle Fitzgerald was innocent—was he not in honour bound to her? And at that moment he realised that he had mistaken pity for love, that Darcy possessed the woman in the world most worth having, and that he was unworthy of her.
His meditations were interrupted by the sound of voices near him. Somebody laid a hand on the other side of the door. They were tampering with it again, and, for more reasons than one, he wanted the fact of his having gained entrance to the tower to remain a secret. Putting the letter in his inside pocket, he softly retraced his steps to the upper chamber.
To his consternation, he had scarcely reached there when the door below was opened. How this had been effected, he did not know. He had been so interested in the documents, that he had had no time to examine the mechanism of the portal. At first he heard only the voices of Riddle and Kingsland. Fearing that the conspirators only were present, and that, being three to one, he might be overpowered, and his precious evidence wrested from him, he endeavoured, by the agitation of the steel curtain and the red light of his lamp, to contrive such ghostly illusions, as should serve to deter them from investigating the upper portions of the tower. It can be imagined therefore what a welcome relief Kent-Lauriston's tones were to him, and the instant he knew that his friend was below, he felt perfectly safe from an attack by force. He therefore lost no time in descending, his footsteps producing, as we have seen, a most startling effect on those below.
