Teacher: Now, understand the problem? Solve this instance: He continued to write fiction, and in 1915 published his most famous work, The Thirty-Nine Steps, a spy-thriller set just prior to World War I. The novel featured Buchan's oft used hero, Richard Hannay, whose character was based on Edmund Ironside, a friend of Buchan from his days in South Africa. A sequel, Greenmantle, came the following year. Buchan then enlisted in the British Army and was commissioned as a second lieutenant in the Intelligence Corps, where he wrote speeches and communiqu*s for Sir Douglas Haig. Recognised for _his_ abilities, Buchan was appointed as the Director of Information in 1917, under Lord Beaverbrook--which Buchan said was ``the toughest job I ever took on''--and also assisted Charles Masterman in publishing a monthly magazine detailing the history of the war, the first edition appearing in February 1915 (and later published in 24 volumes as Nelson's History of the War). <sep>, Pronoun: his <sep>, A: Buchan <sep>, B: Lord Beaverbrook
