London, 1965. A young woman believes that a charismatic psychotherapist, Collins Braithwaite, has driven her sister to suicide. Intent on confirming her suspicions, she assumes a false identity and presents herself to him as a client, recording her experiences in a series of notebooks. But she soon finds herself drawn into a world in which she can no longer be certain of anything. Even her own character. From the author of the Booker-shortlisted novel, 'His Bloody Project'.
