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.

Sir Arthur Conan Doyle was born in Edinburgh in 1859 and died in 1930. Within those years was crowded a variety of activity and creative work that made him an international figure and inspired the French to give him the epithet 'the good giant'.

He was the nephew of 'Dickie Doyle' the artist, and was educated at Stonyhurst, and later studied medicine at Edinburgh University, where the methods of diagnosis of one of the professors provided the idea for the methods of deduction used by Sherlock Holmes. He set up as a doctor at Southsea and it was while waiting for patients that he began to write.

His growing success as an author enabled him to give up his practice and turn his attention to other subjects. His greatest achievement was, of course, his creation of Sherlock Holmes, who soon attained international status and constantly distracted him from his other work; at one time Conan Doyle killed him but was obliged by public protest to restore him to life.

And in his creation of Dr Watson, Holmes's companion in adventure and chronicler, Conan Doyle produced not only a perfect foil for Holmes but also one of the most famous narrators in fiction.

Robert Erskine Childers was born in London in 1870. His parents both died when he was a child, and he was raised at his mother's family home in Ireland. In 1899 he volunteered for service in the Boer War and wrote a popular account of his experiences, following this up with The Riddle of the Sands (1903).

He moved to Ireland after WWI and was elected to the Irish parliament where he was a delegate in the negotiations for the Anglo-Irish treaty of 1922. When the terms fell short of full Irish independence, Childers joined the Republicans in the ensuing Civil War. He was arrested by the Free State government, court-martialled, and executed by firing squad in 1922. Ned Halley is an award-winning journalist
