"...an exciting and splendidly staged English espionage melodrama" – New York Times

Lieutenant-Colonel Graham Seton Hutchison was a First World War British army officer, military theorist, author of both adventure novels and non-fiction works and fascist activist. Seton Hutchison became a celebrated figure in military circles for his tactical innovations during the First World War but would later be criticized for being associated with a series of fringe fascist movements which failed to capture much support even by the standards of the far right in Britain in the interbellum period. He made a contribution to First World War fiction with his espionage novel, The W Plan. Seton Hutchison also published a History of the Machine Gun Corps although this non-fiction work was characterized by its vivid accounts of battle that almost read like a novel.
