Sam Sixkiller: Cherokee Frontier Lawman is a very important book, if only for the fact that it is one of the first, if not the first, biographies of an American Indian law enforcement officer of the Old West.
The book is not about just any American Indian; it chronicles the life of one of the most famous and outstanding lawmen during the frontier era. Authors Howard Kazanjian and Chris Enss, through outstanding research, tell the engrossing story of Cherokee lawman Sam Sixkiller. During his career he was a deputy U.S. marshal under Judge Isaac C. Parker, a captain of the U.S. Indian Police and a railroad detective. This is an outstanding book on the Indian Territory and an American frontier hero.
