A 50th anniversary edition of the first Inspector Wexford novel, with an introduction by Ian Rankin and a new afterword by Ruth Rendell. An ordinary life. An extraordinary death. The trampled grass led to the body of Margaret Parsons. With no useful clues and a victim known only for her mundane life, Chief Inspector Wexford is baffled until he discovers Margaret's dark secret - a collection of rare books, each inscribed from a secret lover and signed only as 'Doon'. Who is Doon? And could the answer hold the key to Wexford solving his first case? "If crime fiction is currently in rude good health, its practitioners striving to better the craft and keep it fresh, vibrant and relevant, this is in no small part thanks to Ruth Rendell". (Ian Rankin).
