Many thoughts occupied Larry’s mind. For some time he had been suspicious of the men on the floor below him. That they were up to no good seemed evident, yet he felt that it was wrong to say, without more proof, that they were up to something bad. They were seldom seen in the daytime, and, though they moved about rather lively at night, Larry could see nothing through the crack that he could say was criminal, or that would bring the men under the law.  
Now, however, that the pawnbroker had told him the money one of the men had given Mrs. Dexter was bad, Larry began to have new suspicions.
 
They were hardly definite enough to warrant his speaking to anyone concerning them, so he resolved to keep a closer watch.
 
“Maybe they have friends who make counterfeit money,” thought Larry, “and they are trying to dispose of it for them. Maybe—” then he stopped in his train of thought suddenly.
 
“I’ll bet they’re the counterfeiters themselves!”198 he exclaimed. “That’s what that strange light meant. That’s what they were doing the night I watched them. They melt the metal up and pour it into moulds. Then they try to pass it off for good coins.”
 
Larry was so excited by his idea that he walked faster than usual, and, the first thing he knew, he was nearly two blocks past his house. He retraced his steps, and found his mother awaiting his return.
 
“Well?” asked Mrs. Dexter, “is the money bad?”
 
“I’m afraid so,” replied Larry.
 
“Then we’ll have to lose it,” said Mrs. Dexter. “I don’t want to ask the man to take it back. He might say I got it somewhere else.”
 
“That’s right, mother,” spoke Larry. “Say nothing about it to the man. If he offers you any more money, or asks for change, don’t take any or give any.”
 
“Why, Larry? What’s the matter?”
 
“I can’t say yet,” replied the boy. “I’ve had my suspicions for some time, but I want to be sure. I’ll speak to Mr. Newton about it.”
 
That night Larry kept a close watch, through the crack in the floor, on the men below, but their place remained in darkness. None of them seemed to be at home, and Larry was wishing there was some way of getting into their apartments so he could see what they were making.
 
199 “Never mind, my chance may come yet,” the boy thought, as he went to bed, to dream of being captured by a band of counterfeiters who were about to melt him into a big half-dollar to get rid of him, when he awoke with a start.
 
The sun was shining in his eyes through his window and it was time to get up and go to work. He found plenty of things to do at the office that day, and so had no chance to speak to Mr. Newton about the money matter. He was somewhat surprised to read an item in the paper bearing on the very subject that was uppermost in his mind.
 
There was an account of an investigation that the United States authorities had started, to discover the source whence a number of bad coins seemed to be circulating about New York.
 
A number of detectives had been detailed on the work of running the counterfeiters to earth, the article said, and, in the meanwhile, the public was cautioned to be careful what money was accepted in change. Bad half-dollars were especially numerous, it was stated.
 
Larry felt sure that the men, in the room below his, were the counterfeiters. He was confirmed in this belief that same day when he had gone on an errand for Mr. Emberg to police headquarters.
 
As he was standing in the main room, waiting for Mr. Newton, to whom he had been sent with a note, he saw two detectives, whom he knew by sight, talking earnestly together in a corner.
 
200 Larry did not want to listen to a private conversation, but he could not help overhearing what the men were saying. He caught the words, “counterfeiters,” “bad half-dollars,” and then the men mentioned the number of the house and the street where Larry lived.
 
“They’re after the men below our apartment!” thought Larry. “Those men are counterfeiters, just as I suspected. This will make a fine story for the paper. I hope it will be a beat!”
 
He saw that the detectives were two who were in the habit of figuring rather prominently in the police reports of the papers. Larry recollected that Mr. Newton had once said that both the officers were not as good as some others who did not get half the publicity they deserved.
 
“And they’re the same ones that treated Mr. Newton so mean on that robbery story,” reflected Larry, referring to the officers in conversation. “They wouldn’t give him the story. I wish they were not going to capture the counterfeiters. It’s too good a job for them. They don’t deserve it.”
 
He hardly knew how to act. He knew he must not interfere with the course of the law, yet he would have been glad to see some other detectives, who were more friendly to the newspaper men than the two he heard conversing were, make the capture. Larry realized that to catch the counterfeiters would mean quite a feather in the caps of the officers.
