Elizabeth and Fiona both had their hands on the wall now, as if it were 
Home in a game of tag. But Nell had stopped and was turning her head from side 
to side, surveying the length of the wall as it clambered and tumbled over the 
increasingly rough shape of the land. After some time she held out one hand, 
pointing at a section of the wall a short distance away, and began to move 
toward it.
