"When I was a child, I used to go wandering - disused railway-lines, old barns, dry-stone walls, strangely Pre-Raphaelite copses - it's much more fun to wander than to be guided, and you could do it in those days with freedom and without paranoia. In similar fashion, I try to allow the reader room to wander, even to meander, to almost lose themselves and their grip of the narrative."
