Mr. Havens was about to continue when Ben motioned him to look in the direction of the blaze, still showing on a shelf of the slope to the north. The fire was burning green.
“What does that mean?” the boy asked.
“It means that they are talking to some person on the other side of the valley or in the valley,” Mr. Havens answered. “It struck me, when the fire was first pointed out, that no man in his right mind would be apt to set up a camp in that exposed position.”
“Just before I called your attention to the fire,” Ben remarked, “it was showing red. There, you see,” he added, in a moment, “it is turning red right now! Of course the lights mean something to some one.”
“That busts your theory about the fellows being mountain tramps!” exclaimed Jimmie. “Such wouldn’t be carrying red and green fire and rifles with Maxim silencers!”
“They may be mounted policemen after all!” suggested Mr. Havens.
“Not on your whiskers!” exclaimed Carl. “Do you think mounted policemen wouldn’t know how to skin a bear, or know how to broil a bear steak? You just bet your life these fellows know more about riding on the elevated or in the subway than they do about traveling on horseback!”
“Well,” Mr. Havens went on, “one of you boys watch the lights and the others listen to the story of how the crooks got Colleton. It may be necessary in the future that you should know exactly how the trick was turned. After a long investigation, and after bribing several men in the factory where the alleged remedy was manufactured, Mr. Colleton secured the exact formula in use during the current week. He also secured a long list of names of persons to whom the bogus remedy manufactured that week had been shipped.”
“Then, why didn’t he drop down on the concern?” asked Carl.
“He did!” was the answer. “He arrested the officers of the company and subpœnaed scores of witnesses. He also secured proof that men in the employ of the government had been bribed by the Kuro concern to retard the work of the inspector and to assist in the destruction of any proof submitted to the commissioner by him.”
“Why didn’t you say that before?” asked Jimmie. “If you’d just said that Colleton was fighting the department at Washington as well as the patent medicine concern, we would have understood what kind of a case we were getting into.”
“Well, you know it now!” laughed Mr. Havens. “At last,” he continued, “Colleton had his case ready for the grand jury, the district commissioner having placed the respondents under heavy bail to await such action.”
“And what happened then?” asked Carl.
“He lost his proof and he lost himself,” smiled the aviator. “Colleton expected a long fight before the grand jury, a fight in the district court, a fight in the circuit court, a fight in the court of appeals, and a final fight before the United States Supreme court, for he knew that the Kuro people had plenty of money and the kind of influence which counts in an emergency.”
“And then what happened?”
“Colleton knew that he had a legal fight on his hands, but he never suspected that he had a personal fight. One day he disappeared from his office in the post-office department at Washington, and his proof disappeared with him. He has never been seen by his friends since that day.”
“And now we’ve got to find him!” exclaimed Jimmie.
“That’s what we’ve got to do!” echoed Carl.
“But, I don’t understand how they got him out of his own room, and got his proof out of the building without attracting attention!” Ben suggested. “They must have had several operatives at work.”
“They certainly did!” was the reply. “Colleton was sitting in his office at three:fifteen one Monday afternoon. The safe in which his papers were kept was locked. The desk in which his memoranda were stored was also locked. When last seen sitting at his desk, he was making memoranda concerning a case not at all connected with the Kuro matter. These papers were not taken.”
“That was bad editing!” Ben laughed. “They should have taken all the papers in sight in order not to disclose the real object of the robbery. The rascals slipped a cog there!”
“The first error in the whole case,” Mr. Havens went on. “Only for the fact that Kuro papers were taken exclusively, it might have been claimed that the respondents in some of the other criminal cases being handled by Colleton had committed the outrage.”
“Where did Colleton go when he left his office?” asked Ben.
“That’s exactly what we don’t know.”
“Who saw him leave his office?”
“No one.”
“Well, then, who saw any one enter his office?”
“No one.”
“Well,” laughed Ben, “how could Colleton get out of his office without being seen? Perhaps he went out unobserved and took the proof with him! You haven’t said whether the safe and desk were opened.”
“They were opened,” was the reply, “by some one knowing the combination to the safe, and some one having a key to the desk. All the proof collected by Colleton disappeared that day.”
“And the patent medicine men finally got up to his price!” grinned Jimmie. “I guess it’s the old story!”
“That’s what makes it so provoking,” said Mr. Havens, impatiently. “A good many people in Washington are saying the same thing. It is unjust to the inspector and very annoying to his friends.”
“And no one went into his office that afternoon?” asked Carl.
“Not that we know of.”
“And no one went near his office door?” asked Jimmie.
“I didn’t say that!” replied Mr. Havens. “His office door opens on a wide corridor, at that time being used as desk space by an overflow of clerks. At three:ten that afternoon two men stopped at Colleton’s door, but did not enter.”
“How do you know they didn’t enter?” Carl broke in.
“No one saw them enter or come out. No one heard the door open or close. One of the men, a heavily-built, bearded fellow, seemed to be urging the other to enter Colleton’s room. The man who was being urged was younger, thinner, and appeared to be greatly excited.”
“Were they the only men seen at that door about that time?” asked Ben.
“So it is said,” was the reply.
“And Colleton was at his desk just before the men were seen at his door?” asked Jimmie.
“Five minutes before!”
“And the person who entered his room after the two men departed found it vacant?”
“That’s the idea exactly!”
“Did you say the young thin man was excited?”
“Perhaps excited is not the correct word,” was Mr. Havens’ reply. “He seemed to be dazed with fear. The clerk sitting near the door received the idea that the man had nerved himself up to the point of confessing a crime or a dereliction of duty, and had lost his courage when he reached the door of the inspector’s room.”
“Did this young man look like Colleton?” asked Ben.
“Not at all. Colleton wore a light moustache only. This man wore a full beard. Colleton’s eyes are bright, snappy, far-seeing. This man’s eyes looked dull and lifeless under the glasses he wore. Colleton is straight, alert, confident. This man dragged his feet as he walked and his shoulders hunched together.”
“Where did the two men
