At first, Mamie tried to resume her work at box-making. But she had had so much leisure and had lived so well that she found the work irksome and the pay inadequate. Mamie knew many women pickpockets and shop-lifters, friends of her husband. When some of these adventurous girls saw that Mamie was discontented with her lot, they induced her to go out and work with them. So Mamie became a very clever shop-lifter, and, for a time, made considerable money. Then many of the best "guns" in the city again tried to make up to Mamie, and marry her. Johnny was not on the spot, and that, in the eyes of a thief, constitutes a divorce. But Mamie still loved her wayward boy and held the others back. In the meantime Johnny had become a great traveller. He knew that the detectives were so hot on his track that he dared to stay nowhere very long; nor dared to trust anyone: so he worked alone. He made a number of daring robberies, all along the line from Montreal to Detroit, but they all paled in comparison with a touch he made at Philadelphia, a robbery which is famous in criminal annals. He had returned to Philadelphia, hoping to get a chance to send word to Mamie, whom he had not seen for years, and for whom he pined. While in the city of brotherly love he was "tipped off" to a good thing. He boldly entered a large mercantile house, and, in thirteen minutes, he opened a time-lock vault, and abstracted three hundred thousand dollars worth of negotiable bonds and escaped. The bold deed made a sensation all over the country. The mercantile house and the safe manufacturers were so hot for the thief that the detectives everywhere worked hard and "on the level". Johnny was not suspected then, and never "did time" for this touch. For a while he hid in Philadelphia; boarded there with a poor, respectable family, representing himself as a laborer out of work. He spent the daytime in a little German beer saloon, playing pinocle with the proprietor; and was perfectly safe. But his longing for Mamie had grown so strong that he could not bear it. He knew that the detectives were still looking for him because of the old crime, and that they were hot to discover the thief of the negotiable bonds. He sent word to Mamie, nevertheless, through an old pal he found at Philadelphia, and arranged to see her at Mount Vernon, near New York. The two met in the side room of a little saloon near the railway station; and the greeting was affectionate in the extreme. They had not seen one another for years! And hardly a message had been exchanged. After a little Johnny told Mamie, proudly, that it was he who had stolen the negotiable bonds. "Now," he added, "we are rich. After a little I can sell these bonds for thirty cents on the dollar and then you and I will go away and give up this life. I am getting older and my nerve is not what it was once. We'll settle down quietly in London or some town where we are not known, and be happy. Won't we, dear?"
