“The detective officer, when he arrives, will soon ferret out the truth, however, depend on that,” observed Mr Ludlow, as he and Stephen mounted their horses to ride back. But neither the captain nor Charley were inclined to wait till the said detective should arrive to win back what they valued so much. Charley thought again and again over the subject, and talked to Tom about the light, and the groan, and the dear little slipper, and suddenly Tom slapped his leg and said that he remembered when the Tower was being put in order that one of the workmen had told him that there was a vault or cellar under a part of it, from which a passage was said to lead down to the seashore. He was not certain whether the captain had heard the account, at all events he did not appear to have believed it, and of course had forgotten it altogether. Tom confessed that he was very stupid not to have thought of it before, though he was not even then much inclined to believe in the truth of the story.
Charley thought differently, and resolved at once to search for the opening—if such existed—to the vault. He charged Tom not to tell the captain, as it would be a disappointment to him should they fail to make the discovery they hoped for. At that very juncture blind Peter, having heard a rumour of the supposed abduction of Miss Margery, came to the Tower to learn whether or not the story was true.
Charley immediately took him into his counsels. Peter thought over the subject. Yes, he had heard the account of the vault under the Tower, and what was more, he knew an old mason residing about two miles off who had worked there, and who was, he rather thought, the very man who had told him of it. He would go off at once and fetch John Trowel and his tools, and they would very soon burrow into the molehill if one existed.
Charley and Tom occupied the time of Peter’s absence in preparing with a rope and a lantern to explore the cavern they hoped to find. They forgot at first that they might possibly encounter opposition, as it was certain that if the cavern did exist it had had occupants, and probably had still, who would not welcome any intrusion on their privacy. Charley, however, at length thought of this. It did not for a moment make him hesitate about carrying out his plans, but he thought that it would be wise to provide himself and Tom with arms. The captain had a brace of pistols and a fowling-piece, and Tom had an old French cutlass which he had taken from the enemy, and treasured as a trophy of his fighting days. Charley at once went up to the captain, who was writing to the officers of the coastguard, and to others who might possibly hear something of his little girl. “Any news? any news?” he asked, as Charley entered.
“No, sir, but if we could find our way into some of the smugglers’ hiding-places, we might learn more than we do now, and as I would rather have a weapon in my hand than trust to my fists with such gentry, I beg that you will lend me your firearms.”
The captain made no answer, but pointed to them over the fireplace, where they hung, with a flask of powder and a bag of bullets.
Charley hurried off to avoid having any questions asked him. Tom was delighted to get the weapons, and declared that, although he had but one arm, he could use his cutlass as well as any man. He then put on a belt that he might stick a pistol in it, and advised Charley to do the same, that he might hold the gun ready for use. At last old John Trowel arrived with Peter. He remembered perfectly all about the vault, had once been down it, and thought that he could find the entrance without difficulty, though it had been been blocked up; but as to a passage leading down to the beach—of that he could not speak with any certainty.
“No time is to be lost, though!” exclaimed Tom, when he heard this. “Come along, and mind you make as little noise as possible.”
The old mason went at once up to the very spot where Tom had seen the light, and he began immediately to work there, scraping away the mortar from between the stones, Charley and Tom helping him, while blind Peter held the lantern. They worked on patiently, knowing that by such means people have frequently let themselves out through the thick walls of a prison. More than half-an-hour had been thus employed when Charley felt the stone on which he stood move; jumping off it, with but little difficulty he lifted it up, when a regular wooden trap-door appeared below. This it was soon found was made to open downwards and how to force it open without making a noise was the question.
Again Charley had to hurry off to the captain’s room to borrow a centrepiece, a small saw and a file, and by labouring with these steadily the bolt which held up the trap was cut round, and Tom then having securely fastened a rope to it, the trap was noiselessly lowered and a dark vault appeared below. There could now be little doubt by which way the pretended ghosts had found their way into the Tower. On a lantern being lowered a ladder was seen, on to which Charley immediately jumped, and fearlessly descended into the vault. As a sailor, he knew the importance of securing a fresh hold before letting go of the first, so he held on to the beam above till he had found a firm rest for his feet. He thus descended for a considerable depth, while Tom let down the lantern by a rope that he might see the nature of the place into which he had got. He at length reached the bottom, and taking the lantern from the end of the rope, commenced an examination of the place in which he found himself. It was a large roughly-hewn vault, which looked as if it had been the quarry from whence the stone with which the fortress was built had been taken. Around it were cells, where some rusty iron bars and ring bolts let into the rock showed that it had been the prison of the castle, and Charley shuddered as he thought of the unhappy people who had once been confined there, where not a gleam of light nor the slightest sound could pierce through the solid rock. As soon as Tom found that Charley had reached the bottom, he also descended—holding his cutlass in his teeth—as actively as most men could have done with two hands. Peter and old John Trowel were directed to wait above. Peter said that from his acuteness of hearing he should be able to judge what progress they were making, and to let Captain Askew know where they were gone.
