This is a thread on a different board (there are others but none as good as this one) and I wanted to see what you guys would say.
For me, beyond a doubt, the scariest fiction book I read has got to be 'Salem’s Lot. It’s been damned near 40 years since I read it and I’m still haunted by the son from The Dick Van Dyke show floating by the one kid who lived’s window. I dunno why this scary vampire boy is fixed in my head as DVD’s son but he is.
As for non-fiction, it was either Killer Clown or Buried Dreams. I don’t remember which book about John Wayne Gacy it was. All I know is I’d read a bit, he killed a kid and I put the book down vowing to never read another page and then I’d pick it up again. In my head I kept thinking: these are real boys. This really happened. I can’t read about another person’s horrible last moments. But I did. I needed to see that fucker fry.
