“There is a mystery about this which stimulates the imagination;
where there is no imagination, there is no horror.”
~Sherlock Holmes, A Study in Scarlet
(It’s actually more accurate, technically, to say this is a quote from Arthur Conan Doyle, but I’m attributing it to Holmes here because while Doyle wrote the words, the mouth he put them in was Sherlock’s. I don’t know about anyone else, but I prefer to think of it in the context of the story it emerged in. As a quote form the world’s greatest detective, spoken while he was working his case, instead of as a literary quote. Funnily enough though, it works well either way, and in both contexts it speaks volumes about the horror genre in fiction, about how it functions. Just look at Lovecraft’s stories, or some of King’s or Barker’s. Many of them illustrate the point quite nicely.)
Horror, truly good horror, often relies heavily on our imaginations.
