...of a checkpoint

There was only one light in the checkpoint, a reading lamp with a green shade, but the glow of the arclights, like artificial moonlight, filled the cabin. Darkness had fallen, and with it silence. They spoke as if they were afraid of being overheard. Leamus went to the window and waited. In front of him the road and to either side the Wall, a dirty, ugly thing of breeze blocks and strands of barbed wire, lit with cheap yellow light, like the backdrop for a concentration camp. East and west of the Wall lay the unrestored part of Berlin, a half-world of ruin, drawn in two dimensions, crags of war.
