Wagontongue — Elmer Kelton

As a slave, Isaac Jefford went to war and saved the life of his master, Major Lytton. As a free man, Isaac became one of the major's top cowhands, respected--but never totally accepted--by fellow cowboys: when they gathered around the fire to eat their dinner, Isaac took his food and sat on the wagontongue alone.
When Pete Runyan, a bitter southerner, joins the crew, Isaac has to swallow his rage more than once. But then Pete and Isaac are assigned the task of getting cash--profits from the sale of the herd--safely to the Fort Worth bank before a foreclosure deadline. Time and three gunmen on their trail are against them, and their journey becomes a race to prove who is the best man.
First published in 1972 by Bantam as a mass market paperback, "Wagontongue" is one of Elmer Kelton's classic novels, exploring racial relations on the West Texas plains in the low-key, wry, and compassionate voice that characterizes Kelton's novels. The novel grew from a short story, included in this volume.
