I gave away my hardcover book club edition of Danse Macabre sometime in the mid-late 80s, sigh. I just didn't see it as that important of a book at the time. I really wish I had it back! I've not heard of Paperbacks From Hell but it sounds great. The lurid book covers were also used for true crime novels, which I went through like Kleenex in the 80s and 90s.
