Dodge City is the second of three historical novels depicting the life of fictional plains adventurer, Lane Collier. This time Collier is a professional bison hunter during the great Southern herd slaughter of the early 1870's. He has formed a successful partnership with Abraham Marmaduke McKnight, a wildly notorious thumper, gambler and whore monger. In spite of his lack of civility, McKnight is also a loyal, honest and dedicated friend. The men set off on one last hunt south of the "Dead Line" into hostile Indian country to pursue the last remnants of the great herd.
