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.
 
Presently she heard Ann crying with all her might; and crying so very naturally that she could hardly persuade herself that it was not real. She glanced over her shoulder at her, and discovered that she had broken the nice sticks of candy into a great many little pieces; and it was for this purpose that she had gone into the alley. Katy was indignant when she saw so much valuable merchandise thus ruthlessly mutilated, and the sale of it spoiled. She was disposed to present herself to the artful girl, and soundly lecture her for the deceit and wickedness: but she wanted to see how the game was played.
 
"Boo, hoo, hoo!" sobbed Ann Grippen, apparently suffering all the pangs of a broken heart, which could not possibly be repaired.
 
"What is the matter, little girl?" asked a benevolent lady, attracted by the distress of Ann.
 
"Boo, hoo, hoo!" cried Ann, unable to speak on account of the torrents of wo that overwhelmed her.
 
"Don't cry, little girl, and tell me what the matter is," continued the kind lady.
 
"Boo, hoo, hoo! I fell down and broke all my candy," sobbed Ann.
 
"Poor child!" exclaimed the sympathizing lady.
 
"My father'll beat me because I didn't sell it," added Ann.
 
"He is a cruel man. Are you sure he will punish you?"
 
"Yes, ma'am," groaned Ann. "He'll whip me almost to death if I don't bring home half a dollar."
 
"You can tell him you fell down and broke the candy," suggested the lady.
 
"He won't believe me; he'll say I sold the candy and spent the money. O, dear me."
 
"You can show him the pieces."
 
"Boo, hoo, hoo! Then he'll say I broke it on purpose, because I was too lazy to sell it; and then he'll kill me—I know he will."
 
"I will go and see him, and tell him about the accident. Where do you live?"
 
"Down North Square. He ain't to home now," replied Ann, who was not quite prepared for this method of treating the subject.
 
"Poor child! I pity you," sighed the lady.
 
"O, dear me!" cried Ann, exerting herself to the utmost to deepen the impression she had made.
 
"How much do you want to make up the value of your candy?"
 
"Half a dollar."
 
"There it is, poor child! If it will save you from abuse, you are welcome to it."
 
"Thank you, ma'am. It may save my life," replied Ann, as she took the half dollar and put it in her pocket.
 
"What an awful liar she is!" said Katy to herself, as the lady hurried on, probably much pleased with herself as she thought of the kind act she supposed she had done.
 
Katy was curious to know what her unworthy assistant would do next, and she followed her down Hanover Street, and saw her stop before the American House. She could not believe that Ann would have the hardihood to play off the same trick again so soon; and she was very much surprised and very indignant when she saw her begin to cry with all her might, just as she had done before. While the deceitful girl's eyes were covered with her apron, in the extremity of her grief, Katy contrived to get on the hotel steps behind her, so that she could see and hear all that passed.
 
"What is the matter with that girl?" asked a gentleman, who presently appeared at the door, addressing another who was just behind him.
 
"It is the broken candy dodge," replied the second gentleman. "That trick has been played off a dozen times within a week."
 
"What does it mean?" asked the first. "I don't understand it."
 
The second explained the trick, precisely as Katy had just witnessed it in Court Street.
 
"Now, don't say a word," he continued. "I have a counterfeit half dollar in my pocket, and you shall see how it is done."
 
With this announcement of his purpose, he accosted Ann, who told him about the same story she had told the lady, and he finally gave her the counterfeit half dollar, which Ann did not suspect was a bad one.
 
"How abominably wicked she is," exclaimed Katy, as she followed her up the street. "But I will soon spoil all her fun, and cut off her profits. I will teach her that honesty is the best policy."
 
It was easier for Katy to resolve what to do than it was to do it; for the wicked girl could easily get her stock through another person. As she walked up the street, Ann lightened her load by eating the pieces of broken candy, upon which she seemed to feed with hearty relish. At a window in Court Street, Ann stopped to look at some pictures, when she was joined by another of the candy sellers, and they walked together till they came to an unfrequented court, which they entered. Katy could hear enough of their conversation, as she followed them, to ascertain that they were talking about the tricks Ann had practiced. In the court they seated themselves on a door-stone, and as they talked and laughed about the deceit, they ate the pieces of candy.
 
"There," said Ann, "I have made a dollar and ten cents this afternoon. You don't catch me walking all over the city for twenty-four cents, when I don't get but eight of that."
 
"I ain't so smart as you," modestly replied Julia Morgan, the other girl.
 
"You'll learn," said Ann, as she took out her money and exhibited the two half dollars.
 
"I don't think people woul............
