Bought this probably when I was in college or shortly after from the bookstore that used to be in South Campus on Beacon Street - Boston Book Annex it was called, and it was my favorite because they had this long, stuffy and hot room that was full of old paperbacks that were, if I remember, 3 for $1 if they had a squiggly line on the front page, as my copy of Horror Hunters has. Now I have few outlets for such retail therapy.
(Unrelated: read the wikipedia article on Roger Elwood- sounds like kind of a dick!)
Talk about starting with a whimper! I must've fallen asleep at least six times trying to read "Ancient Sorceries" by Algernon Blackwood. It intentionally leaves its reader in a stupor, but perhaps too much of one. And it stagnates for much too long, repeating over and over again the townspeople's resemblances to cats.
"The Gateway of the Monster" by William Hope Hodgson is a straightforward "battling a poltergeist" story, but I like it because it seems like something someone would read for pointers in another horror story.
I don't know if H.P. Lovecraft is really capable of not taking himself too seriously, but he seems to in "the Unamabale," and this meta-story on the familiar tropes of his fiction was a nice surprise from him.
I had to refer back to "The Thing on the Roof" by Robert E. Howard presently because I forgot what it was about. Truth be told, it's not a bad story, but it's like Lovecraft fan fiction written by a friend of his.
I hated "Mr. Ames' Devil" by August Derleth. I'm glad these kind of snarky lazy-joke farts that pad short story collections are mostly extinct.
"In the X-Ray" by Fritz Leiber has a shock ending anyone can see a mile away but it'd make a fine Night Gallery episode.
I didn't immediately take to "One Foot in the Grave" by Theodore Sturgeon, what with its (as another reviewer mentioned here) "men's club" style and perspective, but in fact Sturgeon has a nice way with words ("she moved her mouth, chewing apparently the end of sleepiness") and he seemed to have fun writing this and it shows. This story also seemed the most original of the eight, what with its "curse of the hoof foot" and all.
Finally, "I Kiss Your Shadow" by Robert Bloch had its eerie moments, when it wasn't devolving into a Perry Mason episode.
