Not a discovery, not an oddity, but appropriate for Halloween (more or less). It's something of a grab bag with the first section comprised of translated ghost and supernatural stories, including "The Reconciliation" that was filmed as Kwaidan. There's a brief middle with essays on cicadas, Japanese women's names and old songs before closing with a section of "Fantasies" that seem to be basically prose poems of Hearn's own composition.
