Mr. Sumner gave a long sigh.

"I am glad I am rid of that man," he said.

"So am I," responded Hal. "He is a worse villain than you think, Mr.

Sumner."

The elderly broker smiled faintly.

"You still think him connected with the disappearance of the tin box, I suppose."

"I do."

"The police are almost certain they are on the right track of the criminal. I cannot give you the details, but the party is not Hardwick."

"The police don't know everything. Hardwick is thoroughly bad, and he is in league with d.i.c.k Ferris and Mr. Allen."

"You speak very positively, Hal."

"Because I know what I am speaking about, sir."

"You say Hardwick is in with d.i.c.k Ferris?"

"Yes, sir."

"How do you know?"

"Because they formed a plot to have me arrested. But that is not the worst of it. Hardwick made an attempt on my life because I followed him."

"Is it possible?" Mr. Sumner was now thoroughly interested. "Why did you not tell me of this before?"

"Because I wished to follow out the matter on my own hook, and, besides, I am almost a stranger to you, and you might think I was making up a yarn."

"No, Hal, I trust you thoroughly. I don't know why, but you have something about you that seems perfectly honest."

"Thank you." The youth was blushing. "I will never deceive you, Mr.

Sumner, and you may depend on it."

"Tell me about this attempt on your life?" said the broker.

Standing by Mr. Sumner's desk, Hal related very nearly all that had occurred since his first appearance at the office. The broker listened with eager attention.

"You are right," he said, when Hal had concluded. "And apparently Ferris is as bad a villain as Hardwick. But how do you account for Mr. Allen being in with them?"

"On account of that conversation I overheard on the ferry-boat that night. They may try to explain it away as they please, I am convinced that they were talking of robbing your private safe."

"But Mr. Allen comes of very fine connections----" began the broker.

"That may be, but didn't you just say he didn't do just right?"

"So I did, and it is true. But that might be put down to a mere matter of sharp business practice, legally right if not morally so. But this other----"

And the elderly broker shook his head.

"If a man will cheat legally, I don't think he will stop at cheating any other way," replied Hal. "He may for a while, but his conscience soon gets blunted, and that's the end of it. You say the police think somebody else is guilty?"

"Yes."

"Do they think the thief came through the window?"

"Yes."

"That the man who came in while I was here had nothing to do with it?"

"That is their theory."

"But that doesn't explain one point."

"And what is that?"

"Why the marks on the window-sill, which are very plain and made by dirt and ashes, did not extend to the safe."

"Didn't they?"

"No."

"Humph! Who discovered that?"

"I did."

"When?"

"The day the two detectives were here."

"Did you say anything about it?"

"No, sir."

"Why not?"

"Because, as I said before, I wished to sift the matter myself, if I could. I know I am nothing but a boy, but I intend to do all I can toward getting back your bonds."

"Well, you are smart, Hal, there is no denying that. What is your opinion of the marks?"

"I think they were only a blind."

"Put there to form a wrong impression?"

"Exactly, sir. That robbery was committed by somebody who came in through the office, and who knew the combination of the safe."
