In the edgy atmosphere of London in 1965, 'Case Study' delves into the unnerving intersection of sanity, identity, and truth. An unassuming young woman embarks on a covert mission, adopting a pseudonym to unveil the dark secrets behind her sister's suicide. Suspecting the involvement of a beguiling psychotherapist named Collins Braithwaite, she becomes his patient, only to be sucked deeper into a disorienting world of doubt and deception. As she records each daunting encounter, the reader is presented with both her personal notes and Braithwaite's life story. Graeme Macrae Burnet crafts an intoxicating tale that oscillates between earnest investigations and the fragile grasp of reality, ensnaring the reader in a web where nothing is as it seems.
