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 tranquillity of his
English manor to the Scottish Borders and, ultimately, to Scandinavia.
On the remote Island of Sheep, a final confrontation takes place and
everything is decided - once and for all. 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.
