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.
John Buchan was born in Perth. His father was a minister of the Free Church of Scotland; and in 1876 the family moved to Fife where in order to attend the local school the small boy had to walk six miles a day. Later they moved again to the Gorbals in Glasgow and John Buchan went to Hutchesons' Grammar School, Glasgow University (by which time he was already publishing articles in periodicals) and Brasenose College, Oxford. His years at Oxford - 'spent peacefully in an enclave like a monastery' - nevertheless opened up yet more horizons and he published five books and many articles, won several awards including the Newdigate Prize for poetry and gained a First. His career was equally diverse and successful after university and, despite ill-health and continual pain from a duodenal ulcer, he played a prominent part in public life as a barrister and Member of Parliament, in addition to being a writer, soldier and publisher. In 1907 he married Susan Grosvenor, and the marriage was supremely happy. They had one daughter and three sons. He was created Baron Tweedsmuir of Elsfield in 1935 and became the fifteenth Governor-General of Canada, a position he held until his death in 1940. 'I don't think I remember anyone,' wrote G. M. Trevelyan to his widow, 'whose death evoked a more enviable outburst of sorrow, love and admiration.'
John Buchan's first success as an author came with Prester John in 1910, followed by a series of adventure thrillers, or 'shockers' as he called them, all characterized by their authentically rendered backgrounds, romantic characters, their atmosphere of expectancy and world-wide conspiracies, and the author's own enthusiasm. There are three main heroes: Richard Hannay, whose adventures are collected in The Complete Richard Hannay; Dickson McCunn, the Glaswegian provision merchant with the soul of a romantic, who features in Huntingtower, Castle Gay and The House of the Four Winds; and Sir Edward Leithen, the lawyer who tells the story of John MacNab and Sick Heart River, John Buchan's final novel. In addition, John Buchan established a reputation as an historical biographer with such works as Montrose, Oliver Cromwell and Augustus.
