Come Out, Ye Gifted Kings and Queens

I don't know if this is the first time I've done this or not, and I don't currently feel like checking the archives, but anyhow, so, like, in about four months it will be October, and every October, including, for reasons that escape me, this coming iteration, I write about horror fiction every day for the entire month, all posts falling under the The Kind of Face You Slash title. I've been doing this for four years now, and while I have the structure and general approach down, it can be a struggle to find enough material to write about for 31 days straight. Now I fully understand this is not because there is any kind of paucity of horror literature available, but one person -- me, in this scenario -- can only learn about so much of it, and anything I can do to ease that burden will, you know...ease my burden.

So I'm asking: any recommendations? I already know some writers I'm planning to cover, like Graham Joyce, Gaston Leroux, Seabury Quinn, Quentin S. Crisp, and Walter De La Mare, so you needn't bother recommending them. I also try to not repeat authors, although sometimes I feel it's necessary, and have done it on more than one occasion. But if you click on that link (and honestly I don't know if that links to every Kind of Face You Slash post I've ever written, but it should show most of them) and at least scroll through, you should have some idea of what I've already gone over. But even of those authors already touched on, if you know of a particular story by one of them that you really think I should check out, don't hesitate to tell me about it. I'd already written about Ramsey Campbell on at least two other occasions when a reader recommended I check out Campbell's story "The Companion," which I did, and which was awesome, and which I wrote about, so good was it. So don't let the concept of "ground well covered" stop you.

Mainly, though, I'm looking for fringe stuff. By which I don't, or don't necessarily, mean horror writers who wallow to varying degrees of childishness in sex and violence, but stuff that has been unfairly overlooked, or, better yet, forgotten. Even if you think I might know a particular book or author, tell me anyway, because I might not, or might not know too much about it, or whatever. Just recommend away. Recommend like the wind. Below in the comments, please, if you will. Thanks.
