Lizzie Randall, the preacher's daughter, is murdered. The men of the west Texas town are set on lynching Paco Morales, a Mexican teenager who happened to be in the vicinity at the time. No proof, but, after all, he is only a Mexican. Reason and/or conscience work on most of the would-be lynchers, so that, in the end justice is served. The list of suspects grows to include almost everyone in the story, thus providing an agreeable tangle of clues.
