If you've never read #RobertChambers' story collection #TheKingInYellow--
The first four stories are masterpieces of macabre horror fiction. The one after that is almost unsettling by how it isn't as creepy as the first ones. And the last stories are pretty traditional and boring, as are the stories Chambers would write the rest of his career.
Almost as if he was driven mad by reading the play The Yellow Sign himself and as a reaction retreated into writing boring contemporary romances! Or maybe he was replaced by some supernatural entity trying to hide the fact of the original Chambers' disappearance!
