When I was an obsessive climber, Shropshire was just a corridor you went down to get to Wales. You turned right or left at Birmingham, depending whether you’d come north or south. The effect of blinkering yourself in that way is that you accidentally save up unexplored territories. By 2005, whole areas of the country were overwhelming me with the sudden, pure clarity you feel in childhood and adolescence–nostalgia for landscapes you’ve yet to investigate, places you’ve yet to know. Shropshire, the South Downs, the Rhinogs: the world seemed new again, but now it was set up perfectly for an old head. I was certain I could make something out of this feeling, but publishing–which would rather you didn’t find things new again, for fear you might wander off on the wrong track–got in the way and since then writing has been a process of struggling back to a lost start point, through a substance a bit like glue.
