Thus it was that Rex Carshaw, eligible young society bachelor, was drawn into the ever-widening vortex of "The Yacht Mystery." He did not recognize it yet, but was destined soon to feel the force of its swirling currents. Gazing from a window of the otherwise deserted house Winifred saw both her assailant and her protector marched off by the policeman. It was patent, even to her benumbed wits, that they had been arrested. The tailing-in of the mob behind the trio told her as much. She was too stunned to do other than sink into a chair. For a while she feared she was going to faint. With lack-lustre eyes she peered into a gulf of loneliness and despair. Then outraged nature came to her aid, and she burst into a storm of tears. CHAPTER VI BROTHER RALPH. Clancy forced Senator Meiklejohn's hand early in the fray. He was at the Senator's flat within an hour of the time Ronald Tower was dragged into the Hudson, but a smooth-spoken English man-servant assured the detective that his master was out, and not expected home until two or three in the morning. This arrangement obviously referred to the Van Hofen festivity, so Clancy contented himself with asking the valet to give the Senator a card on which he scribbled a telephone number and the words, "Please ring up when you get this." Now, he knew, and Senator Meiklejohn knew, the theater at which Mrs. Tower was enjoying herself. He did not imagine for an instant that the Senator was discharging the mournful duty of announcing to his friend's wife the lamentable fate which had overtaken her husband. Merely as a perfunctory duty he went to the theater and sought the manager. "You know Mrs. Ronald Tower?" he said. "Sure I do," said the official. "She's inside now. Came here with Bobby Forrest." "Anybody called for her recently?" "I think not, but I'll soon find out." No. Mrs. Tower's appreciation of Belasco's genius had not been disturbed that evening. "Anything wrong?" inquired the manager. Clancy's answer was ready. "If Senator Meiklejohn comes here within half an hour, see that the lady is told at once," he said. "If he doesn't show up in that time, send for Mr. Forrest, tell him that Mr. Tower has met with an accident, and leave him to look after the lady." "Wow! Is it serious? Why wait?" "The slight delay won't matter, and the Senator can handle the situation better than Forrest." Clancy gave some telephonic instruction to the man on night duty at headquarters. He even dictated a paragraph for the press. Then he went straight to bed, for the hardiest detectives must sleep, and he had a full day's work before him when next the sun rose over New York. He summed up Meiklejohn's action correctly. The Senator did not communicate with Mulberry Street during the night, so Clancy was an early visitor at his apartment. "The Senator is ill and can see no one," said the valet. "No matter how ill he may be, he must see me," retorted Clancy.
