GUILTY BY DEFINITION (PB)

When an anonymous letter is delivered to the Clarendon English Dictionary office, it becomes clear that this is not the usual enquiry. The letter hints at sinister events linked to a particular year. For editor Martha Thornhill, the date can mean only one thing: the summer her brilliant older sister Charlie went missing. Ten years on, Martha and her family are no closer to unravelling the mystery of Charlie's disappearance - until now. A love letter to language and the city of Oxford, wrapped within an intriguing mystery.
