I wetted my finger and held it up above my head, but could feel nothing. The night was as still as it was foggy. Seeing, therefore, that it was no use our waiting about in the hope of the weather improving, I bade them good night, and, having been congratulated on my ruse for getting rid of Peach, and the success which had attended it, went below to my berth.

Sure enough when we came on deck next morning the fog had disappeared, and with it the schooner Nautch Girl. A brisk breeze was blowing. Overhead the sky was sapphire blue, brilliant sunshine streamed upon our decks, while the sea around us was as green and transparent as an emerald. Little waves splashed alongside, and the schooner danced gaily at her anchor. After the fog of the previous night, it was like a new world, and when we had satisfied ourselves that our enemy was really out of sight it was a merry party that sat down to breakfast.

As soon as the meal was finished we returned to the deck. The same glorious morning continued, with the difference, however, that by this time the sea had moderated somewhat. The crew were already at work preparing the diving apparatus for my descent. After the anxiety of the Nautch Girl's arrival, the trick we had played upon her captain, and the excitement consequent upon it, it came upon me almost as a shock to see the main, or to be more exact, the only, object of my voyage brought so unmistakably and callously before me. I glanced over the side at the smiling sea, and as I did so thought of the visit I was about to pay to the unfortunate vessel which was lying so still and quiet beneath those treacherous waves. And for what? For a jewel that would ultimately decorate a mere earthly sovereign's person. It seemed like an act of the grossest sacrilege to disturb that domain of Death for such a vulgar purpose.

"I see you are commencing your preparations," said Mr. Leversidge, who had come on deck while I was giving my instructions to the man in charge of the diving gear. "Before you do so had we not better study the cabin plan of the vessel herself, in order that you may have a good idea as to where the berth you are about to visit is situated?"

"Perhaps it would be as well," I answered. "Where is the plan?"

"I have it in my portmanteau," replied the old gentleman, and a moment later, bidding me remain where I was, he dived below in search of the article in question. Presently he returned, bringing with him a sheet of paper, which, when he spread it out upon the deck, I recognised as one of those printed forms supplied by steamship companies to intending passengers at the time of booking.

"There," he said, as he smoothed it out and placed his finger on a tiny red cross, "that is the cabin our agent occupied. You enter by the companion on the promenade deck, and, having descended to the saloon, turn sharp to your left hand and pass down the port side till you reach the alleyway alongside the steward's pantry. Nineteen is the number, and our agent's berth was number one hundred and sixty-three, which, as you will observe from this plan, is the higher one on your left as you enter. The next cabin was that occupied by the Reverend Colway-Brown, who, as you are aware, was one of the persons who escaped. I think we may consider ourselves fortunate that he was a parson, otherwise we don't know what might have happened."

Taking up the plan he had brought and examining it carefully, I tried to impress it upon my memory as far as possible. "Now," I said, "I think I know my ground; so let us get to work. The sooner the business is finished and the pearl is in your keeping the better I shall be pleased."

"I shall have no objection to be done with it either, I can assure you," he answered. "It has been a most tiresome and unpleasant affair for everybody concerned."

I then strolled forward to the main hatch, beside which my dress had been placed. Everything was in readiness, and I thereupon commenced my toilet. To draw on the costume itself was the matter of only a few seconds. My feet were then placed in the great boots with their enormous leaden soles; the helmet, without the glass, was slipped over my head and rivetted to the collar plate around my neck, the leaden weights, each of twenty-eight pounds, were fastened to my chest and back, the life-line was tied round my waist, and the other end made fast to the bulwark beside which my tender would take his place during such time as I should remain below.
