Silver City - Harold Lamb

Ex-army sergeant Pat Flynn and a young Negro called Tobias had come to Silver City to seek their fortune through their combined skills of marksmanship and fist-fighting. All goes to plan until Tobias is given the job of town sheriff, but when the railway enters Silver City its Southern owners' hatred for blacks turns young Tobias into a killing machine. Taking to the hills he rescues a pretty Indian squaw named Nahita from a gang of outlaws. Her village having been wiped out, she and Tobias are two outcasts determined to seek revenge.
