A long-forgotten promise made by Richard Hannay finds him honour-bound to resolve a violent vendetta in which the lives of a young father and his daughter are in danger from unscrupulous and desperate men. Hannay sets out on a high-octane chase from the rural tranquility of his English manor to the Scottish Borders and, ultimately, to the remote Island of Sheep. This, the last of the Hannay adventures – and the last of Buchan's novels to be published during his lifetime – is a rare gem of high drama interwoven with Buchan's personal beliefs about the problems of a post-war world. With an introduction by Andrew Lownie. This edition is authorised by the John Buchan Society.
