"Isn't it true that some Indians do not believe in fighting by night?"
"That is true of some. They believe the soul of a man killed at night must wander forever in darkness; but there are skeptics among the Indians as well as among ourselves. I've never paid much attention to such generalities, and it would be just my luck to run into a non-believer with a good rifle."
(from Callaghen, by Louis Lamour)
