The lady pressed her handkerchief to her eyes in an agitated way.

“Mrs. R——,” said the detective, “what is your desire in this matter? To what point do you wish me to prosecute inquiries?”

“I want to see with my own eyes enough to convince me of what I suspect. I also want witnesses, so I can instigate suit for divorce. I will not lead the life I am now living any longer.”

She then handed the detective a ten-dollar bill.

On the day following the next, when she came to Mr. Keeling’s office to hear his report, he said:

“I dropped into the store this afternoon on some trifling pretext. This young woman was already there, but she did not remain long. Before she left, she said: ‘Charlie, we will have a jolly little supper tonight as you suggest; then we will come around to the store and have a nice chat while you finish that setting for the diamond broach with no one to interrupt us.’ Tonight, Mrs. R——, I think, will be a good time for you to witness the meeting between your husband and the object of his infatuation, and satisfy your mind how matters stand.”

“The wretch,” cried the lady with flashing eyes. “He told me at dinner that he would be detained late tonight with some important work. And this is the way he spends his time away from me!”

“I suggest,” said the detective, “that you conceal yourself in the store, so you can hear what they say, and when you have heard enough you can summon witnesses and confront your husband before them.”

“The very thing,” said the lady. “I believe there is a policeman whose beat is along the street the store is on who is acquainted with our family. His duties will lead him to be in the vicinity of the store after dark. Why not see him, explain the whole matter to him and when I have heard enough, let you and him appear as witnesses?”

“I will speak with him,” said the detective, “and persuade him to assist us, and you will please come to my office a little before dark tonight, so we can arrange to trap them.”
