I had no compunctions on the score of their discomfort, for I felt that I had a score to settle with each of them. The way in which each took my rudeness, however, was characteristic of the men. Harry Underwood's face grew black for a minute, then it cleared and he laughed boisterously. "You little devil," he said, "I'll pay you for that. Ever get kissed under water? Well, that's what will happen to you before this day is over." Dr. Pettit's face did not change, but into his gray eyes came a little steely glint. He said nothing, only smiled at me. But there was something about both smile and eyes that made me more uncomfortable than Harry Underwood's bizarre threat. I was so unskilled in this game of banter and flirtation that I was at a loss what to say. Recklessly I grasped at the first thing which came into my mind. "You'll have to catch me first," I said, daringly, and turning, ran swiftly out toward the open sea. I am only a fair swimmer, but the sea was unusually calm, so that I went much farther than I otherwise would have dared. When I found the water getting too deep for walking I started swimming. As I swam I looked over my shoulder. The two men were following me, both swimming easily. Dr. Pettit was in the lead, but Harry Underwood, with powerful strokes, was not far behind him. I concluded that Dr. Pettit had been the swifter runner, but that the other man was the better swimmer. As I saw them coming toward me, I realized that I had given them a challenge which each in his own way would probably take up. I was dismayed. I felt that I could not bear the touch of either man's hand. In another moment my punishment had come. Dr. Pettit overtook me, stretched out his hand, just touched me with a caressing, protecting little gesture, and said in a low tone, "Don't be afraid, little girl: If you will accord me the privilege, I will see that your friend does not get a chance of fulfilling his threat." I knew that he intended his words for my ear alone, but he had not counted on Harry Underwood's quick ear. That gentleman swam lazily toward us, saying as he passed us, with a malicious little grin: "Better go slow upon that protecting-heroine-from-villain stunt. I see Friend Husband is getting a bit restless." He forged on into the surf, with long, powerful strokes that yet had the curious appearance of indolence which invests every action of his. Startled at his words, I looked toward the place where I had last seen Dicky romping in the waves with Grace Draper. The girl was swimming by herself. Dicky, with rapid strokes, was coming toward us. "For the love of heaven, Madge!" he said, angrily, as he came up to us. "Haven't you any more sense than to come away out here? This sea is calm, but it is treacherous, and you are farther out than you have ever gone before. Come back with me this minute."
