“ Baldy must know all this. Sperry found himself in a quandary. If he accomplished the arrest of Cairns, if he could find some one who would listen to him and act, it meant the arrest of Baldy, or at least his pursuit, and Baldy would know that Sperry, whom he had befriended, had double crossed him. He had a good excuse, his own vindication, but—he had eaten Baldy’s salt! More, he was himself mixed up with the gang. Baldy’s friendship might have been only the ruse to use him as a tool, to procure the driver they needed, to act as outside man—a mere matter of business. ”
