The place of horror turns out to be no more than a green scoop, sometimes shadowed, sometimes shining with the bilberries and grass within it, as if a mouth had opened from which streamed a beam of light. So my uncle Robert's death, which had looked from a distance to be an all-consuming tragedy was, close-up, the story of a man finding release from his pain and how his brother had showed such defiant love. The past was a grave, a trap - and yet, also neither of these. Just light, coming and going. At the wolf pit you imagine you will stare into a hole littered with bones, but what draws you to that place is not what you take from it. The wolf pit seems a delicate illusion. You walk towards it; there is nothing, just a curve of the moor; then it is a soft green light, and then it is nothing again.
