  Quotations
  He was tempted to try the last door—to look into the room of evil fame; but he reflected that this would be indiscreet, since Colonel Capadose handled the brush—as a raconteur—with such freedom. There might be a ghost and there might not; but the Colonel himself, he inclined to think, was the most mystifying figure in the house.
  1888, Henry James, The Liar
  It is notoriously possible for the author of a fictitious narrative to become, after a time, unable to distinguish it from a statement of actual facts. There is a case on record in which a learned judge communicated to the Psychical Society in perfect good faith a ghost story, all the principal features of which were proved to be imaginary. They had their origin in his own talent as a distinguished raconteur.
