Father Brown sat bolt upright in the boat and crossed himself. His movement was so abrupt that his friend asked him, with a mild stare, what was the matter.
'The people who wrote the mediaeval ballads,' answered the priest, 'knew more about fairies than you do. It isn't only nice things that happen in fairyland.'
'Oh, bosh!' said Flambeau. 'Only nice things could happen under such an innocent moon. I am for pushing on now and seeing what does really come. We may die and rot before we ever see again such a moon or such a mood.'
'All right,' said Father Brown. 'I never said it was always wrong to enter fairyland. I only said it was always dangerous.'
G. K. Chesterton
