"I am obliged to you," said Max. "You may be quite sure I shall respect your confidence. I will be on my guard for the future."

"I'm glad to hear it," the captain replied and added: "I've noticed that you've been playing cards with him lately."

Max admitted the soft impeachment. He might have added that he had lost more than he cared to remember. He felt certain in his own mind, however, that Moreas had obtained the money honestly, and in common fairness he felt compelled to say so to the captain.

"I don't doubt it," the other answered. "He is not such a fool as to try anything else while it is possible for him to get it by straightforward play. But if you must play with him I should advise you to keep your eyes and wits open. It is not in my interest to say so, for if you find him out you will come to quarrelling, and then possibly to blows, and at that point it will be my duty to step in. But I don't want to have to do it. As a rule, we carry very few passengers on this boat, but I can tell you that I have seen some funny scenes on board her now and again, and Moreas has figured conspicuously in more than one of them."

As it transpired, the captain's warning reached Max just in time. Another day and it might have been too late. The incident I am about to relate took place on a warm morning. They were nearing the Equator, and Max was stretched on the poop skylight, reading, when Moreas made his appearance. The latter offered him an excellent cigar, and after they had been smoking for a time proposed a game of ecarté. Max, who, I regret to say, was an inveterate gambler, immediately assented, not, however, without thinking of the captain's warning. His companion immediately produced a pack of cards. The steward, on being appealed to, brought a small folding table from below, whereupon the game commenced. For some time they played with varying success, then Max, contrary to custom, began to win. They doubled the stakes and played again. Once more Max won. They played another hand, still with the same result. An ominous look flashed into Moreas' eyes, but it was gone again as quickly.

"I am glad to see that your luck has turned at last, Señor," he said, with a suspicion of a sneer about his lips.

"Fortune must smile some time or other," retorted Max coolly. "It would be hard indeed if I were always to have the same luck that I've had of late. It is your deal, I fancy."

Moreas accordingly dealt, and they played the next hand. Suddenly Max laid down his cards, back uppermost, and leant across the table.

"Forgive me, Señor," he said, "but I feel sure there is some little mistake. We have played two rounds, and I see that you still have four cards in your hand."

The remainder of the pack was lying at the Spaniard's elbow, and Max noticed a suspicious movement of the other's sleeve a few seconds before. Had he not spoken when he did, the other would have rid himself of one of his cards without delay.
