Poor and Proud by Oliver Optic

The next day was Wednesday, and as school kept but half a day, Katy resolved to spend the afternoon in finding out which of her employees was in the habit of practicing the deception which Mrs. Gordon had described to her. She could think of no one upon whom she could fasten the guilt, unless it was Ann Grippen, who, she thought, would be more likely to play such a trick than any other. After she had delivered their candy, she put on her things and followed the girls down to State Street, where they separated. Ann went up Court Street, and Katy decided that she needed watching, and so she followed her.

It was a very tedious afternoon to the little wholesale merchant, but the dignity of the trade depended upon her efforts in seeking the offender. Ann entered various shops, and seemed to be having very good luck with her stock. At last she appeared to grow tired of her labors, and turned into an alley. Katy wondered what she was going to do there, for it was certainly no place to sell candy. She waited sometime for her to come out, and when she heard her steps, she placed herself at the corner of the alley, in such a position that Ann could not see her face.
