"Good girl!" said Jones. "She's learning. Can you handle this alone, Norton? They want me out of the house again, for I believe they were after me as well as Florence. Half an hour gone!" "Trust me!" cried Norton. And he ran out to his auto. It was a wild ride. Several policemen shouted after him, but he went on unmindful. They could take his license number a hundred times for all he cared. So they had got her? They could wait till their enemy's vigilance slacked and then would strike? But Susan! The next time he saw Susan he was going to take her in his arms and kiss her. It might be a new sensation to kiss Susan, always so prim and offish. Corey Street--that had been her direction. They had put Florence in a motor boat at the foot of Corey Street. He was perhaps half an hour behind. Florence never opened her lips. She stared ahead proudly. She would show these scoundrels that she was her father's daughter. They plied her with questions, but she pretended not to hear. "Well, pretty bird, we'll make you speak when the time comes. We've got you this trip where we want you. There won't be any jumping overboard this session, believe me. We've wasted enough time. We've got you and we're going to keep you." "Let her be," said Vroon morosely. "We'll put all the questions we wish when we're at our destination." And he nodded significantly toward the ships riding at anchor. Florence felt her heart sink in spite of her abundant courage. Were they going to take her to sea again? She had acquired a horror of the sea, so big, so terrible, so strong. She had had an experience with its sullen power. They had gone about four miles down when she looked back longingly toward shore. Something white seemed to be spinning over the water far behind. At first she could not discern what it was. As she watched it it grew and grew. It finally emerged from the illusion of a gigantic bird into the actuality of an every-day hydroplane. Her heart gave a great bound. This flying machine was coming directly toward the launch; it did not deviate a hair's breadth from the line. Fortunately the men were looking toward the huge freighter a quarter of a mile farther on, and from their talk it was evident that the freighter was to be her prison--bound for where? Nearer and nearer came the hydroplane. Was it for her? It was impossible for the men not to take notice of the barking of the engines at last. "The thing's headed for us!" Vroon stared under his palm. It was not credible that pursuit had taken place so quickly. To test yonder man-bird he abruptly changed the course of the launch. The hydroplane veered its course to suit. Florence heard her name called faintly. One of the men drew his revolver, but Vroon knocked it out of his hand. "There's the police boat, you fool!" "Jump!" a voice called to Florence. She flung herself into the water without the slightest hesitation.
