At the International Conference Centre in Geneva, Hannah Rossier, formerly Annie Price, comes face to face with Neville Weir, someone from her childhood whom she never expected, or wanted, to meet again. As Neville’s reasons for attending the conference become clear, the dark waters of Hannah’s past start to rise. Hannah is a psychotherapist, with a specialist interest in memory and how connections are made between past and present. She has reinvented herself successfully, moving from a small northern town in England to Lucerne, Switzerland, with her husband, Thibaut. Nobody, not even Hannah, knows the full truth about herself. Her ‘memories’ consist of glimpses of the place where she played in childhood, known simply as ‘The Wild’. Over the three days of the conference she has to decide whether she can avoid Neville, or whether she should submit to an encounter with him and with her past. And in her keynote lecture about the neuroscience of memory, how much to conceal or reveal. But can her specialism save her from drowning?
