The taxicab in which he had made the trip down was still waiting for him. An hour later he had reached his hotel. The disguise of the night before he had discarded. The woman in the cab had penetrated it. His presence, and that of Mrs. Morton, at the uptown hotel, was known. There seemed to be no further purpose, for the present, in attempting to preserve his incognito. He went to his room at once, and knocked on the door which separated it from the apartment of Mrs. Morton and her daughter. The door was opened by the maid, who ushered him into the little parlor. "I will tell Mrs. Morton that you are here," the girl said, and went into the next room. Mrs. Morton came out presently, her face pale and drawn. Duvall knew at once that she had been up all night, watching, no doubt, beside her daughter. "How is Miss Ruth?" he asked. "She is better. She had a fairly good night's rest, and her fever has left her." "I am glad to hear that. I hope there have been no further threats." "No. Not yet. But I never know at what moment something may happen. It is terrible--terrible, living under a shadow like this." As she spoke, the telephone bell rang. "You answer it, Mr. Duvall," she said, turning quickly to the door by which she had entered, and closing it. "I do not think I can stand anything more at present." Duvall took down the receiver. Someone was asking for Mr. John Bradley. "This is Mr. Bradley," he said, then suddenly recognized his wife's voice. "Is this you, Richard?" she asked. "Yes. What is it?" "If you have time, to-day, come down and see me. I have something I want to tell you. Something important." "Very well. I will be there in half an hour. Good-by." He hung up the receiver. "Was it anything--anything _more_, Mr. Duvall?" asked Mrs. Morton. "No. Nothing of that sort. Well, I must go along now. I merely looked in to ask after your daughter. There is one thing I want you to do, however, and that is, let me have a key to your apartment on 57th Street." Mrs. Morton took the key from her purse, and handed it to him. "Haven't you any good news, yet?" she asked, somewhat pathetically. "Not yet--at least nothing very definite. I know the woman who is annoying your daughter by sight, however, and I think I can safely assure you that she will be under arrest before very long. Matters of this sort take time, Mrs. Morton. Remember that I have had charge of the case but three days, and these people we are looking for are shrewd, leaving few clues. But I feel that I shall have something definite to report very soon now." "I hope so, I'm sure. Good day." "Good day." Duvall left the room, and taking a taxi, drove down to see Grace. He found her sitting at the writing desk, in the reception room of their suite, apparently busy over a letter. She pushed the sheet of paper aside, when her husband entered, and threw her arms about his neck.
