I suppose the best way to tell the story is simply to narrate it, without an effort to carry belief. The thing did not require belief. It was not a feeling of horror in one's bones, or a misty outline, or anything that needed to be given actuality by an act of faith. It was as solid as a wardrobe. You don't have to believe in wardrobes. They are there, with corners. (The Troll)
