"Really, this is outrageous!" cried the old maid. "If I were in her place I would make you suffer for this calumny."
"Probably I know her better than you do. I am a salesman in Marshall Field's drygoods store, and this lady is a notorious shoplifter. She is varying her performances to-day. I have a great mind to call a policeman. She deserves arrest."
Had a bombshell exploded in the car, there would not have been a greater sensation. The woman rose without a word, and signaled to have the car stopped.
"Now, sir," went on the young man, sternly, "if you are a gentleman, you will apologize to this boy for your unworthy suspicions, and you, too, madam."
The old maid tossed her head, but could not find a word to say, while the old gentleman looked the picture of mortification.
"We are all liable to be mistaken!" he muttered, in a confused tone.
"Then be a little more careful next time, both of you! My boy, I congratulate you on your triumphant vindication."
"Thank you, sir, for it. I should have stood a very poor chance without your help."
The tide was turned, and the uncharitable pair found so many unfriendly glances fixed upon them that they were glad to leave the car at the next crossing.
