London, 1965. 'I have decided to write down everything that happens, because I feel, I suppose, I may be putting myself in danger,' writes an anonymous patient, a young woman investigating her sister's suicide. In the guise of a dynamic and troubled alter-ego named Rebecca Smyth, she makes an appointment with the notorious and roughly charismatic psychotherapist Collins Braithwaite, whom she believes is responsible for her sister's death. But in this world of beguilement and bamboozlement, neither she nor we can be certain of anything. Case Study is a novel as slippery as it is riveting, as playful as it is sinister, a meditation on truth, sanity, and the instability of identity by one of the most inventive novelists of our time.
