Also, Morrow makes an egregious error (ok, maybe it's just the narrator who is unreliable) when he says the source material for The Haunted Palace is Lovecraft's Colour Out of Space, rather than The Case of Charles Dexter Ward.
I stumbled on an essay by Morrow about the book, and find myself half-lamenting that I don't live in the alternate universe in which his first idea was completed:
As my wife and I walked out of the lamentable Roland Emmerich version of Godzilla, I turned to her and said, “You know, even in degraded form, it’s still a potent myth. I’m going to try doing something with it myself.”
So I went home and outlined a novel called What Rough Beast, which I never wrote. According to my notes, Godzilla travels to Washington DC in 1995 to inspect the controversial Enola Gay exhibition at the Smithsonian Institute, his intention being to incinerate the city unless the curators prove willing to acknowledge certain political, military, and human truths about Hiroshima.
Yeats, fer Crissakes. Read a book!
