Great line in Treasure Island by Robert Lewis Stevenson:
“Sperrit? Well, maybe,” he said. “But there’s one thing not clear to me. There was an echo. Now, no man ever seen a sperrit with a shadow; well, then, what’s he doing with an echo to him, I should like to know? That aint in natur’, surely?”
‘This argument seemed weak enough to me. But you can never tell what will affect the superstitious…’
