The detective hunted up the policeman and explained the situation.

“That’s funny,” said the guardian of the peace. “I didn’t know R—— was a gay boy at all. But, then, you can never tell about anybody. So his wife wants to catch him tonight. Let’s see, she wants to hide herself inside the store and hear what they say. There’s a little room in the back of the store where R—— keeps his coal and old boxes. The door between is locked, of course, but if you can get her through that into the store she can hide somewhere. I don’t like to mix up in these affairs, but I sympathize with the lady. I’ve known her ever since we were children and don’t mind helping her to do what she wants.”

About dusk that evening the detective’s client came hurriedly to his office. She was dressed plainly in black and wore a dark round hat and her face was covered with a veil.

“If Charlie should see me he will not recognize me,” she said.

Mr. Keeling and the lady strolled down the street opposite the jewelry store, and about eight o’clock the young woman they were watching for entered the store. Immediately afterwards she came out with Mr. R——, took his arm, and they hurried away, presumably to their supper.

The detective felt the arm of the lady tremble.

“The wretch,” she said bitterly. “He thinks me at home innocently waiting for him while he is out carousing with that artful, designing minx. Oh, the perfidy of man.”

Mr. Keeling took the lady through an open hallway that led into the back yard of the store. The outer door of the back room was unlocked, and they entered.

“In the store,” said Mrs. R——, “near the bench where my husband works is a large table, the cover of which hangs to the floor. If I could get under that I could hear every word that was said.”
