For several months Marnie, a middle-aged poet and mother, has experienced sightings of her long-dead identical twin sister, Perdita, across London. As a consequence, and due to her crippling writer's block, she has sought the help of octogenarian Harley Street shrink, Schlap, to work through her problems. Not least her repeated dreams of being a man.
Schlap has problems of his own though, having recently suffered a silent stroke which has affected his memory.
Or is he more aware of reality than Marnie herself?
Marnie's long-suffering partner and their three teenage kids are not helping matters, either. Neither is Marnie's bohemian Alpha-course attending mum, her diabetic chef dad, nor the inquisitive family dog. Perhaps Marnie's encounter and blossoming friendship with a woman who she thinks is the living embodiment of long-dead author Katherine Mansfield will provide the key to unlock her mind.
