McCloskey nodded. "You mean Hallock?"

"Yes."

The trainmaster was half-way to the door when he turned suddenly to say: "You can fire me if you want to, Mr. Lidgerwood, but I've got to say my say. You're going to let that yellow dog run loose until he bites you."

"No, I am not."

"By gravies! I'd have him safe under lock and key before the shindy begins to-night, if it was my job."

Lidgerwood had turned to his desk and was opening it.

"He will be," he announced quietly. "I have sworn out a warrant for his arrest, and Judson has it and is looking for his man."

McCloskey smote fist into palm and gritted out an oath of congratulation. "That's where you hit the proper nail on the head!" he exclaimed. "He's the king-pin of the whole machine, and if you can pull him out, the machine will fall to pieces. What charge did you put in the warrant? I only hope it's big enough to hold him."

"Train-wrecking and murder," said Lidgerwood, without looking around; and a moment later McCloskey went out, treading softly as one who finds himself a trespasser on forbidden ground.

The afternoon sun was poising for its plunge behind the western barrier range and Lidgerwood had sent Grady, the stenographer, up to the cottage on the second mesa to tell Mrs. Dawson that he would not be up for dinner, when the door opened to admit Miss Brewster.
