Described by the author as 'a psychological horror story inspired by the Capgras delusion [the belief that a loved one has been replaced by an identical double]. It explores themes of womanhood, powerlessness and madness. It’s also a little ode to such works as The Yellow Wallpaper, by Charlotte Perkins Gilman, and Margaret Atwood’s Alias Grace.'
