A taut psychological exploration of obsession, betrayal and the dangerous relationship between a patient and therapist in 1960s London. In the quiet hush of her therapist's office, Evelyn Westbrook finds herself revealing secrets she'd prefer to keep hidden. Abandoning her successful modelling career to become a model wife for her husband, Henry, has left her days feeling empty. Her mother-in-law is pressing for a child that Evelyn doesn't want. And her nights are haunted by a recurring nightmare in which she becomes a snake devouring its own tail. As Evelyn's sessions with the enigmatic Dr. Daley unearth more questions than answers, her interest in him turns into obsession. But is her therapist finally providing the care she needs, or is she being manipulated? A compelling novel about identity, power, and the cost of playing the roles we never chose.
