“What interest have you got in this matter?” he asked.

“Wouldn’t anybody be interested in so mysterious a thing as happened at the Sanborns?”

Again she laughed mockingly at Chick.

“How did you come to know me?” asked Chick.

“Are you not a celebrated person, and doesn’t everybody know Chickering Carter, the great Nick Carter’s chief assistant?”

Chick knew now that the young woman was playing with him, and that he did not have easy game before him.

“No,” he said, “I am not so celebrated in the circles in which you move that you would know me.”

“What do you mean by that?” asked the young woman.

“I mean that you saw me for the first time to-day, and that it was at the Sanborn house where I was on duty and you were there as a guest.”

By the way the young woman took this reply, Chick knew that he had scored a point, but did not know how much of a one it was.
