Surly Dick's aspect changed. He became morose again, and looked silently at his feet for a few moments, as if he were debating something in his own mind. He was, in truth, perplexed; for, while he was extremely anxious to bring his hated comrades to justice, he was by no means so anxious to let the lieutenant into the secret of the treasures contained in the caverns of the Isle of Palms, all of which he knew would be at once swept hopelessly beyond his grasp if they should be discovered. He also reflected that if he could only manage to get his late companions comfortably hanged, and himself set free for having turned King's evidence against them, he could return to the island and abstract the wealth it contained by degrees. The brilliant prospect thus opened up to him was somewhat marred, however, by the consideration that some of the pirates might make a confession and let this secret be known, in which case his golden dreams would vanish. The difficulty of making up his mind was so great that he continued for some time to twist his fingers and move his feet uneasily in silence.
Mulroy observed the pirate's indecision, and, although he knew not its cause to the full extent, he was sufficiently acquainted with human nature to know that now was the moment to overcome the man, if he was to be overcome at all.
"Well, well," he said, carelessly; "I'm sorry to see you throw away your only chance. As for the information you refuse to give. I can do without it. Perhaps I may find some of your late comrades when we make the island, who will stand witness against you. That will do, my man; you may go. Mr. Geoffrey" (turning to a midshipman), "will you accompany that pirate forward, and see that he is put in irons?"
"But you don't know where the island is," said Surly Dick, anxiously, as the lieutenant was turning away.
Mulroy turned back: "No," said he; "but you ought to know that when a seaman is aware of the existence of an island, and knows that he is near it, a short time will suffice to enable him to find it."
Again he was about to turn away, when Dick cried out, "Stay, sir; will you stand by me if I show you the way?"
"I will not deceive you," said Mulroy bluntly. "If you show me how to steer for this island, and assist me in every way that you can to catch these villains, I will report what you have done, and the judges at your trial will give what weight they please to the facts; but if you suppose that I will plead for such a rascal as you are, you very much mistake me."
A look of deep hatred settled on the pirate's countenance as he said, briefly, "Well, I'll show you how to steer."
Accordingly, Surly Dick, after being shown a chart, and being made aware of the exact position of the ship, ordered the course to be altered to "north-half-east." As this was almost dead in the eye of the light breeze that was blowing the Talisman had to proceed on her course by the slow process of tacking.
While she was in the act of putting about on one of these tacks, the look-out reported "a boat on the lee bow."
