But, as the train drew into the Broad Street station, Patsy, looking out of the window, caught the glimpse of a man trying to board the train before it had fairly stopped. It seemed to him that the man was Lannigan. Quickly warning Chick, they both of them ran back to the car in which Mrs. Ladew was seated and were in time to see Lannigan hastily pass through the car, stopping only long enough to whisper something in the ear of Mrs. Ladew and hurriedly pass on. He went by both Chick and Patsy so closely that their clothes touched, but he did not recognize either and was soon out of sight. Chick and Patsy kept Mrs. Ladew under close observation and saw from her manner that she had evidently been prepared for something by a warning from Lannigan. As the train stopped and Mrs. Ladew descended, they followed her along the stone platform until the iron gates were reached, where were gathered the friends of the arriving passengers. Keeping close enough to Mrs. Ladew to watch all that occurred to her, they saw a gentleman step out from the throng, as she passed through the gate, and, kissing her warmly, ask: “Did you have a pleasant trip?” “Very pleasant, indeed,” replied Mrs. Ladew. “But, Tom, I am surprised and delighted at your meeting me. I did not suppose you would give up so much of your morning to me.” “Oh,” responded the gentleman called Tom, “I was not so busy this morning, and I am glad to get you back.” He laughed a little and added: “You see, I did not know but that Ellison would marry you instead of Miss Sanborn.” “Oh, Tom,” replied Mrs. Ladew, “There has been an awful, awful happening. Ellison disappeared right after the ceremony and the reception guests were dismissed because of it.” By this time the crowd had grown so great about the two that Chick and Patsy could hear no more that passed between the husband and wife. But they followed to the street and saw the pair enter a handsome private carriage. “There’s no use in following them,” said Chick, “for that is Mr. Ladew with her and they will go straight home.” “And she’ll have no chance to talk to any of the people we are after.” “No,” replied Chick. They turned to move away and, in doing so, saw Lannigan watching the carriage drive off, a little way apart. “S--sh,” warned Chick. “There’s Lannigan. He evidently warned Mrs. Ladew that her husband was waiting for her. We must follow him.” “I’m glad of it,” said Patsy. “I was thinking one of us ought to have kept a peeper on him.” Drawing back under the cover of a pillar, they watched to see what direction Lannigan would take. It seemed as if he were waiting for some one, for he did not move until nearly all of those who had been attracted by the incoming train had moved away. But others were gathered to meet another train and so neither Lannigan nor the two young detectives were conspicuous.
