CHAPTER XXXII. — IN WHICH HARRY MAKES AN UNPLEASANT DISCOVERY.

Harry had been the first to escape from the room. He had waited long, fearing lest others might be in the chimney; but at length, as the actions of the new-comer did not seem consistent with those of a pursuer, he had concluded to risk it. He had then entered the chimney, and was able to reach his own room in safety. Ashby had not left until the very last moment, when the door had already opened to admit "His Majesty," so that the two had not met. But Harry, on reaching his own room, stood for a long time in the fireplace, listening; and as he listened, he felt sure that he heard sounds, and these sounds seemed as though made by pursuers. Upon this he flung himself upon his bed, where he lay motionless for nearly an hour, until it seemed scarcely possible that there could be any further danger.

He now thought of returning to the room, but after a little consideration decided not to. No doubt they would all be awake, perhaps also others might be there, and to go back might lead to discovery, and destroy all further chances of seeing Katie. Still, the thought would not be dismissed. Sleep was impossible, and he lay awake, recalling the events of the night.

At length there occurred to his mind the thought of those Spanish bonds which he had found and hidden away so carefully. He had not visited the place since, or rather, he had not looked at the hiding-place. He determined to do so now merely for the sake of reassuring himself as to the safety of those precious papers. For Katie's fortune lay wrapped up in that parcel, and he was anxious that he should be the means of saving it for her. In addition to this, he was anxious to search carefully along the passage-way, to see if there might not be openings which had thus far escaped him—which might possibly lead to the outer world.

He provided himself with his torch and found that he had matches enough. He then climbed up into the passage-way, and lighted his torch; after which he proceeded onward until he reached the chink where the package had been deposited. Here he stooped down and held the light close.

The first sight showed nothing. But the string which he had left hanging out was, as he knew, not very perceptible, so he held the light closer and felt for it. Even then he found nothing.

He now thought that perhaps the package had fallen by its own weight a little farther in, drawing the string after it. In order to find whether this were so or not, he reached his hand into the chink.

No sooner had he done this than he snatched it away, and sat there staring.

The chink was very much larger than it had been before.

There was no doubt about this. Then it had been barely wide enough to admit the package. Now he could easily thrust his whole arm into the opening.

It was utterly unaccountable. By some incomprehensible means that crevice had been enlarged. The whole stone, he now saw, had been thrust forward several inches into the passage-way. It seemed as if nothing short of an earthquake could suffice to move from its place such a stone as that. In itself it appeared to be of vast size and weight, and below it, and above it, and on either side, were others equally vast. How was it possible for such a rock to be thus dislodged? By an earthquake? But nothing of the kind had occurred. He was a light sleeper, and was easily aroused by anything unusual. Could the castle have "settled?" Impossible. It was too old. It had long since shaken down into its deep bed. Still, old buildings do often settle, and in fault of any better explanation he was compelled to adopt something like this.

In any event, there seemed very great danger that the package had been lost. Again and again he thrust his arm far in, but found only vacancy. Then he put his hand downward as far as he could. It touched something which felt like a stone pavement.

This pavement was about eight inches lower than the one upon which he was. All this made the matter still more incomprehensible.

But Harry had come forth to seek after this very thing, namely, some mysterious opening into a side-passage, and after the first surprise it occurred to him that this might be what he wished to find. And now the fact of the stone jutting forth became intelligible, though this new explanation promised ill for the safety of the package. It was evident that this stone was movable, and afforded in some way an entrance to this passage. It seemed strange that so vast a stone should be movable, yet there was the fact. Perhaps also it was less massive than it seemed. Perhaps it was a mere slab and opened like a door. But how?

He now examined its surface with the most careful and minute scrutiny. In vain. Over all the surface and over all the edges there was nothing that indicated any means by which such a stone could be moved—nothing of the nature of hinges, and nothing of the nature of a handle, by which to grasp it so as to move it. Yet it was movable, and had been moved lately. Perhaps it could be moved without any help from a handle.

He now thrust his arm through, and, grasping it, pulled at it with all his strength. His utmost effort, however, made no impression. He found that the stone was massive within as without, that it was no thin slab, but one which his arm could not surround—at least eighteen inches in solid thickness where his arm held it. Yet the stone did move, and had been moved. The matter became now more incomprehensible than ever. It could be moved. It had been moved, yet there was a secret contrivance here into which he could not penetrate.

Again the thought came to him of the package which contained Katie's fortune. Some one had been here. Had that one found the package? It must be so. Fool that he was!

A second time had that precious package been deposited in what seemed a secure hiding-place, and a second time had the hiding-place proved almost a public thoroughfare.

For what seemed a long time Harry examined that stone. In vain. The wall arose before him impenetrable. The stone was immovable. Yet that stone seemed now to him to hold within itself the secret not only of the package, but also of escape and of liberty and life.

Harry at length felt like giving up. Once more, however, though now quite hopelessly, he examined the stone in every direction, pressing with all his strength upon every part. And now in this, the very moment of his utter hopelessness, as often happens—at the very time when not expecting it, he found what he sought.

At the extreme end of the stone, more than six feet from the crevice where he had hidden the package, he pressed upon it, and found that it gave way. The pressure was not at all strong; yet to that slight effort the apparently massive rock yielded like a door, and moved inward several inches.

In unspeakable amazement and intense excitement Harry pushed it in farther, until he saw the whole move in, at his pressure, for about two feet. An opening was disclosed. He stepped in and looked around.

He found himself in a kind of chamber which was about four feet wide and eight feet long. At the end of this was a stone stair-way which went down. Harry looked around, and took all this in at a glance. His first thought was about his package.

The package was not there.

He had been prepared for this, yet the disappointment was bitter. Still there was consolation in the discovery which he had made, and his excitement and curiosity were yet strong. He naturally turned his attention to that stone which formed so wonderful a door-way, and which had so long baffled him.

He saw that at the end, near the crevice, the stone was about eighteen inches thick, but that it was all cut away toward the other end, till it ended in a slab of only two inches in thickness. One end of the stone was thus a vast block, while the other was a comparatively thin slab. He now understood the whole construction.

At the thick end the door was set with stone pivots, into sockets above and below, by means of which it was easily moved. The reason why he could not move it at first was because he was exerting his strength near the hinge, or pivots, where, of course, it was thrown away; but as soon as he had touched the farther edge, it yielded to a slight pressure. Here, inside, there was a stone handle by which it was easily opened, while, outside, he thought that it was closed by swinging it as one went out, so that it went by its own weight into its place.

After all, there was nothing very strange in this. Harry had read about such stone doors. In the accounts of the Moabite cities, mention is made of something of the sort; and as those have lasted for three thousand years, this one might well lust for several hundred.

But the package!

There were no traces of it. At the hinge end of the slab there was a wedge-shaped stone, by inserting which here the door could be secured against opening from without. Into this wedge-shaped crevice he had thrust the package. He saw also that in pushing it far in he had only secured its discovery, for he must have pushed it so far that the first one who passed had found it.

Now who could that have been?

Whoever it was, the package was gone. No doubt it was one of the Carlists, who had taken it to their leader. It was gone beyond all possibility of recovery.

Harry had been so taken up with his examination of these things that he had forgotten all about the necessity of caution. He stood there thus, in thought, the torch brightly burning, when suddenly he was roused by some one rushing up the steps. He darted back into the passage-way, and banged the stone door after him.

Too late. In an instant the pursuer was upon him and had caught at his coat collar.

But Harry was not the man to give up at the first attack. Quick as lightning, he drew forth a revolver from his breast pocket, and, hastily cocking it, turned to confront his assailant.

One look was enough.

"Ashby!" he cried.

"You scoundrel!" cried Ashby, in a fury. "Scoundrel! villain! traitor!"
