The Essex was to sail at eleven o'clock. Half an hour before that time Mark's hackney coach drew up at the wharf. Ten minutes later Dick Chetwynd, who had, like Mark, driven by a circuitous route, and had made several stoppages, joined him, and as they shook hands slipped a parcel into his hand, and this Mark at once pocketed, and buttoned his coat up tightly; then hailing a boat, they went on board together; they had sent their luggage on the previous evening. On getting on board Mark saw the two prize fighters walking up and down the deck aft. They were quietly dressed, and save for their size would have attracted no attention, and would have been taken for two countrymen on their way to Holland on business. The two detectives were seated forward, their appearance being that of two quiet business men, commercial travelers or small traders. The two friends first went below, and saw to the cabin which they were to share, and found their luggage was all there. Then they returned on deck. Four or five other passengers were standing watching the last bales of goods coming on board. The tide was just on the turn, and a quarter of an hour later the warps were thrown off, and some of the sails hoisted, and the Essex began to move through the water. “Look there, Dick!” Mark exclaimed. “Do you see that boat lying on its oars in the middle of the stream? That man sitting in the stern is a foreigner, either from Southern Europe or from India.” “He is certainly a dark man, Mark. Still, that may be only a coincidence.” “It is rather a curious one,” Mark said. “We are too far off to see his features, but he is apparently watching us off. There, the oars are dipping into the water, now he sees that we are fairly under way.” “Well, Mark, I shall begin to think that you are right. I am bound to say that hitherto I thought that it was ridiculous to suppose that you could have been watched as you thought, and that you had got these diamonds on your brain till you had really become fanciful. However, it certainly looks as if you were right; but even if you were, how on earth could they have found out that we were going by this ship?”
