“I think I’ll have to leave you here. My business will make me stay here, for I see that my man is getting pretty well loaded, and I must keep an eye on him.” Chick and Patsy therefore shook hands with him, thanking him for the assistance he had given them. While they talked at the door, a young man and a young woman entered from the street and, walking some distance into the place, suddenly stopped, peered forward earnestly, and then hastily turning, went out into the street again. The action had been observed by Patsy, who made up his mind that they had seen somebody at the tables they desired to escape. He watched them go to the corner and engage in earnest conversation. After a moment, they went under the cover of the corner, where Patsy could see that she took off her hat. A moment later, they stepped out again into the light and, to Patsy’s great surprise, she was a very different looking person. Before she had been a blonde, and now she seemed to be dark haired. “She had a wig on,” said Patsy to himself. “Now I wonder what was the meaning of that?” The couple stood on the corner a little longer, then the two went to the curbstone and, entering a hansom cab, were driven off. Patsy turned to Chick and Merton, who had been conversing while he had thus been watching the couple, thinking that strange sights were to be seen in the Tenderloin late at night. Chick, slipping his arm under Patsy’s, now led him to the sidewalk, and the two turned down Broadway. “Well, Patsy,” said Chick. “I don’t know how much we have gained to-night, but I take it that it is a good deal.” “Do you think,” asked Patsy, as they walked along, “that the young Englishman, the girl Alice talked of, was our man Ellison?” “That notion has got into my head,” said Chick. “And if it is so, it will be a big opening for us. We’ve got a way of finding out, however, and that is, by finding if Ellison was on a yachting trip last September.” “And,” added Patsy, “whether he was in the habit of running over to Philadelphia much.” “That’s so,” said Chick, “I don’t think there is any use of following up Lannigan and the woman, Ladew.” “I don’t know about that,” said Patsy. “We might stumble on their associates if we did.” “Well,” said Chick, “if that is so, we had better go back and watch the front of that place to see them come out.” They had walked along as they had thus talked and had, therefore, gotten something like two blocks below. Chick turned about, suddenly, saying: “You’re right about that, Patsy, and we won’t drop them until we see where they go.” They walked back hastily until they reached the corner on which Patsy had seen the couple that had attracted his attention. Here they heard a voice calling some one, and, turning to look, saw a woman beckoning to them from a hansom cab drawn up to the sidewalk.
