This is a must read for lovecraft fans. Robert W. Chambers is one of the authors upon whom the Cthulhu Mythos was based (lovecraft took names and such from him and used them in his own stories.)
Amazingly, I found the full text of The King in Yellow on the internet. Its a collection of short stories (the first few are lovecrafty, the last three are not really).
Here You Go.
