The fighting tenderfoot

Young Lawyer O'Hara gets an auspicious welcome to the town of Concho--a bullet through his hat, and before he has a chance to put up a shingle, he becomes involved in a bloody war between two cattle titans, Wesley Steelman and David Ingram. It is war without quarter, and among the two gun mercenaries employed by both sides, the most notorious is eighteen-year-old Bob Quantrell. Cheerful and fearless, but a cold-blooded killer, Quantrell is loyal only to his own lightning-fast six-gun. O'Hara learns quickly that Colt and Winchester are the only law in Concho.
