Mr. Standfast

Mr Standfast is the third of five Richard Hannay novels by John Buchan, first published in 1919 by Hodder & Stoughton, London.

It is one of two Hannay novels set during the First World War, the other being Greenmantle (1916); Hannay's first and best-known adventure, The Thirty-Nine Steps (1915), is set in the period immediately before the war started.

The title refers to a character in John Bunyan's Pilgrim's Progress, to which there are many other references in the novel; Hannay uses a copy of Pilgrim's Progress to decipher coded messages from his contacts, and letters from his friend Peter Pienaar.

Set in the later years of World War I, Brigadier-General Hannay is recalled from active service on the Western Front to undertake a secret mission hunting for a dangerous German agent at large in Britain. Hannay is required to work undercover disguised as a pacifist, roaming the country incognito to investigate a German spy and his agents, and then heads to the Swiss Alps to save Europe from being overwhelmed by the German army.
