That night Larry kept a closer watch than usual. He could not see enough to enable him to tell exactly what the men were doing, but he noticed the golden glow flood the apartment, and he knew the men were melting something, for he could hear them talking about whether or not it was hot enough. The number of counterfeit coins continued to increase, and the government inspectors redoubled their efforts to land the gang they were convinced was working in New York. One afternoon, as he was coming from the office, Larry was met in the hall, just outside the apartment of the men under suspicion, by one of them. The man regarded Larry for a few seconds and then said: “Would you mind doing me a favor?” “What is it?” asked Larry, thinking the man might want some more money changed. In such an event the lad was prepared to refuse. He did not propose to have bad coins passed on him. “Will you come in here and give me your opinion?” asked the man, holding the door open. For a few seconds Larry hesitated. He thought the man might be one of the counterfeiters who had discovered he was being watched and who had determined to capture the spy. In such an event Larry felt he would be safer on the outside. Yet he had a boy’s curiosity to see what was in the room about which the men were so secretive. If he could get a look he felt it might help him to know what to do. The man noticed Larry’s hesitation. “You needn’t be afraid,” the stranger remarked. “I know some of the neighbors regard us a little suspiciously, but our work is such that it has to be done where no one can see us.” “What do you want me to do?” asked Larry. “Merely give us your opinion,” spoke the man. “We have an article we want you to look at and tell us if you think it is good, and will be generally acceptable.” Larry was just going to remark that he was not a very good judge of counterfeit money, when he happened to think that would not be a wise remark to make. He saw that the man held the door wide open. There did not seem to be any other persons in the apartment. Larry resolved to risk going in. He thought if the men attempted to harm him he could call loudly enough to bring help. “We want to get the idea of a real American boy on the quality of the work we have done,” the man went on. “Will you please come in?” Then Larry resolved to enter. He nerved himself for an ordeal as he crossed the threshold. “This way,” remarked the man, preceding him, and, going into an inner room, Larry saw before him a pile of bright shining objects. He gave a sudden start. The man noticed it and said quickly: “Now don’t say a word about it. We don’t want anyone to know we are doing this. What do you think of them?” Larry was much surprised at what he saw. He talked for some time with the man, and, when he emerged from the apartment, the boy’s face bore a queer look.
