Jim gets the letter and finds the strongbox, running afoul of Crowley, who shoots him. The sheriff arrests Jim for stealing the box, and Crowley attempts to take the box from the sheriff at gunpoint. The sheriff shoots Crowley, and Crowley, mortally wounded, tells the sheriff that Pete Daley was the man responsible for the original theft of the box.
