Sometimes horror stories play out like puzzles to be solved. That’s not too much of a surprise: plenty of writers have done acclaimed work that falls under the header of both “mystery” and “horror,” after all, from Edgar Allan Poe to Stephen King to Elizabeth Hand. And in these sorts of stories, there’s a sense that the overarching terror might be abated if only a solution is found to something: an ancient crime unearthed, an old price finally paid. But there’s another subdivision of horror that hears a different call: specifically, that horrific events play out under their own logic, and no easy answer can be found for them.
