They could hear the rattle of the boom tackle blocks as the sail was eased across. “That was the mainsail,” he muttered. “Jibed to port when I told him starboard.” Again they lifted on a wave, and again and again, ere they could make out the distant green of the Samoset's starboard light. But instead of remaining stationary, in token that the yacht was coming toward them, it began moving across their field of vision. Duncan swore. “What's the lubber holding over there for!” he demanded. “He's got his compass. He knows our bearing.” But the green light, which was all they could see, and which they could see only when they were on top of a wave, moved steadily away from them, withal it was working up to windward, and grew dim and dimmer. Duncan called out loudly and repeatedly, and each time, in the intervals, they could hear, very faintly, the voice of Captain Dettmar shouting orders. “How can he hear me with such a racket?” Duncan complained. “He's doing it so the crew won't hear you,” was Minnie's answer. There was something in the quiet way she said it that caught her husband's attention. “What do you mean?” “I mean that he is not trying to pick us up,” she went on in the same composed voice. “He threw me overboard.” “You are not making a mistake?” “How could I? I was at the main rigging, looking to see if any more rain threatened. He must have left the wheel and crept behind me. I was holding on to a stay with one hand. He gripped my hand free from behind and threw me over. It's too bad you didn't know, or else you would have staid aboard.” Duncan groaned, but said nothing for several minutes. The green light changed the direction of its course. “She's gone about,” he announced. “You are right. He's deliberately working around us and to windward. Up wind they can never hear me. But here goes.” He called at minute intervals for a long time. The green light disappeared, being replaced by the red, showing that the yacht had gone about again. “Minnie,” he said finally, “it pains me to tell you, but you married a fool. Only a fool would have gone overboard as I did.” “What chance have we of being picked up... by some other vessel, I mean?” she asked. “About one in ten thousand, or ten thousand million. Not a steamer route nor trade route crosses this stretch of ocean. And there aren't any whalers knocking about the South Seas. There might be a stray trading schooner running across from Tutuwanga. But I happen to know that island is visited only once a year. A chance in a million is ours.” “And we'll play that chance,” she rejoined stoutly. “You ARE a joy!” His hand lifted hers to his lips. “And Aunt Elizabeth always wondered what I saw in you. Of course we'll play that chance. And we'll win it, too. To happen otherwise would be unthinkable. Here goes.” He slipped the heavy pistol from his belt and let it sink into the sea. The belt, however, he retained. “Now you get inside the buoy and get some sleep. Duck under.”
