"I don’t like to look out of the windows even - there are so many of those creeping women, and they creep so fast. I wonder if they all came out of the wall-paper as I did?" ~ The Yellow Wallpaper (Charlotte Perkins Gilman)
An excellent white and black image, which gives this being maybe a wolf a lot more presence. As though the viewer is shocked as it suddenly appears through the glass door. Also dark and shady adding extra fear as lots of people are afraid of the dark.
