"That's where you're off, my boy. It might rescue her from peril. If she is in trouble, as we imagine, it would be the very best thing that could happen for her."

"How is that?"

"She could tell her story truthfully, and it might get her out of trouble by putting the man with the black mustache in a box. At the same time it would clear me."

Bart was obliged to confess that Frank had made a point, and still he did not like to think of turning the girl over to the officers of the law.

"Perhaps she would not 'peach' on the gang, if there is a gang behind her, which I doubt. She might keep her mouth closed, might swear she never let you have the queer money."

"And I can prove she did by the conductor of the Pacific Express. He saw me give her the small stuff for the two bills."

"Still, I do not feel like nabbing her and turning her over to the officers. We might not be able to nab her, anyway."

"That is true enough. I rather fancy her companion would be likely to put up a stiff fight. He looks to me like a dangerous man."

Frank fancied that he was beginning to understand Bart's feelings. He believed the boy was afraid the girl might prove to be one of a gang of counterfeiters, and he was so badly smitten that he did not wish to be instrumental in her arrest.

Frank, himself, had been highly interested in Isa Isban; but events had transpired which caused him to doubt that she was all her innocent face would lead a casual observer to believe, and his admiration for her had waned swiftly.
