Part of the Worlds Without End Grand Master Reading Challenge.
Afternote: Loved the cover art for this book.
This one was so promising! Noir meets Cthulhu! But it turned out to be endless bland dialogue and a muddled ending that had me speedreading to get to the last page. I always like Wolfe because he has such a range, especially in the short fiction I have read of his. Come to think of it, An Evil Guest could have been compressed into a great short story.
