“Oh, boy!” cried Hanson, of the firm of Hanson and Debbs. “I’ve suspected this slick fellow Mohun for a long time. Now with Salper’s authority we can go in and clean him out.”

“Salper wouldn’t make an accusation of that sort,” said Debbs thoughtfully, “if there wasn’t something in it. He’s had some sort of inside tip all right.”

“Well,” returned the other briskly, “we’ll let the old man know we’re on the job, and then get busy.”

Accordingly, a few minutes later Bob received and transcribed this message:

“Right. We’ll have him inside of twenty-four hours.”

At the confidence contained in the message Mr. Salper straightened his shoulders as if a great load had been lifted from them and held out a friendly hand to Bob.

“I can’t tell you what you have done for me,” he said, cordially. “Of course I’m not safe yet from the crooked work of these men, but at least Hanson and Debbs have been warned to look out. And that’s two-thirds of the battle.”

“I’m mighty glad we’ve been able to help,” said Bob, adding earnestly: “If there’s anything else we can do please call on us. Mrs. Salper——”

He paused, for at mention of his wife’s name the relief disappeared from Mr. Salper’s face and in its place was the old worried frown.

“Yes—my wife,” he muttered, and, without another word to the boys, turned and stalked out of the room. The man, who had all this time lingered near them, turned and went out after Mr. Salper and the boys were left alone.
