“It was the chief she was talking with over the wire, but there wasn’t any harm done, for he dropped right away that it wasn’t Ida on the other end, and gave the other a throw-off. He cut the connections with his own ’phone.

“If you want to square it right with the chief, go to his place to-morrow morning and put the connections on. I’ll see him to-night and square you with him.”

The young man, expressing satisfaction with this arrangement, went off, after shaking hands with both Chick and Patsy.

But he had gotten no farther than the corner when he stopped short, peered forward eagerly, and came back to the young detectives on a run.

“Say,” he cried. “Come. The young woman is going down the av’noo. Sure, it’s her.”

“The one who worked me on the wires.”

The two followed quickly to the corner, where the man pointed out a woman moving along at a brisk gait down Lexington Avenue.

“Come on, Patsy,” cried Chick.

The young man evidently thought he was in it, too, for he followed after.
