Lonesome Dove, Volume 1 by Larry McMurtry

SO CAPTAIN CALL TURNED back down the rivers, cut by the quirt of Clara's contempt and seared with the burn of his own regret. For a week, down from the Platte and across the Republican, he could not forget what she said: that he had never done right, that he and Gus had ruined one another, that he was a coward, that she would take a letter to the boy. He had gone through life feeling that he had known what should be done, and now a woman flung it at him that he hadn't. He found that he could not easily forget a word Clara said. He could only trail the buggy down the lonely plains, her words stinging in his heart and head.

Before he reached Kansas, word had filtered ahead of him that a man was carrying a body home to Texas. The plain was filled with herds, for it was full summer. Cowboys spread the word, soldiers spread it. Several times he met trappers, coming east from the Rockies, or buffalo hunters who were finding no buffalo. The Indians heard-Pawnee and Arapahoe and Ogallala Sioux. Sometimes he would ride past parties of braves, their horses fat on spring grass, come to watch his journey. Some were curious enough to approach him, even to question him. Why did he not bury the compañero? Was he a holy man whose spirit must have a special place?
