This had passed between Chick and Patsy as they were walking along Broadway above Thirty-fifth Street. Suddenly Merton halted the two, and, pointing to the other side of the street, said: “There’s your couple now.” Looking across they saw a man and a woman, both stylishly clothed, crossing Broadway to the corner on which they stood. The three, dropping back out of sight, watched them cross. Standing on the corner for a moment, the two seemed to discuss which way they should go, then they turned up Broadway. Following them, the detectives learned that their destination was a restaurant whose principal business of the twenty-four hours was done after midnight. It was the resort of the gay people of the town, and, as other places darkened, this one became brighter and gayer. They waited on the outside long enough to make it appear that they had not followed the pair into the place. “It was worth waiting for,” replied Chick, “and we’ll probably get a line on them before we are through with them.” Finally, Chick said to Merton: “We’d better go in now.” He made the motion to lead the way up, when a young woman stepped up, and, addressing Merton, said: “Anything for me to do to-night, Mr. Merton?” “No, Bess, I think not. I haven’t anything on to-night of any importance.” The girl stepped away, and Chick asked who she was. “She is a girl,” said Merton, “who is employed by me a good deal.” “You use her, then, in your work?” “Yes; she’s as good as a directory. She knows everybody, who they are and what they do.” “Fetch her back,” said Chick. “We’ll take her in, and she may be of use to us.” Merton ran after her and brought her back. The four then entered the restaurant. The place was already more than half full, and there was some difficulty in finding a table which was near enough to Lannigan and the woman who was with him to make observation easy and yet not be too conspicuous. When, at last, the table was selected, it was found to be well placed for their purpose. They not only commanded a good view of the table occupied by Lannigan and his companion, but of the whole room. “Chick,” said Patsy, “Lannigan isn’t broke, by any means. He’s doing the swell caper. Nothing but champagne and Burgundy does him. See him mix the fizz and the red.” “Nothing less than seven and a half for that tipple,” said Merton. “And nothing less than birds, as well,” said the girl Merton had called Bess. “His layout will knock spots out of a ten-dollar note,” said Patsy. “You know who it is?” asked Bess. “Know the man,” replied Chick; “his name is Lannigan.” “That’s right,” said Bess. “Do you know the woman who is with him?” asked Chick. “No. She was never seen here until three nights ago, and she was with him then.”
