“Book Descriptions: Along the far reaches of the Chisholm Trail, from deadly Kansas, along hidden outlaw trails, the tall, mysterious man named James Green stopped to ask the same questions, then moved on. A legacy of hatred left to him by a dying man had sent him in search of two men … and a final, deadly reckoning. As he rode he earned a nickname that was whispered whenever men talked about gunfighters, and whenever violence ran rampant in dusty streets. They called him Sudden, and his bitter quest was relentless.
