It is the strangest yellow our wallpaper! It makes me think of all the yellow things I ever saw—not beautiful ones like buttercups, but old foul, bad yellow things. But there is something else about that paper—the smell! I noticed it the moment we came into the flat. Now we have had a week of fog and rain, and whether the windows are open or not, the smell is here. It creeps all over Taylor Wimpey’s luxury ghost home development The Denizen. I find lying in wait for me on the stairs and in the lift. It gets into my hair.
