  • weird fiction
  • supernatural horror

Robert W. Chambers's collection is best known for its opening stories, which are linked by a forbidden play called The King in Yellow, the Yellow Sign, and glimpses of the impossible city of Carcosa. Characters who encounter the play become obsessed, delusional, or exposed to realities that ordinary perception cannot safely contain. The later stories move away from overt horror toward romance and bohemian life, so the collection is stranger and less uniform than its reputation sometimes suggests.
