'The best story of adventure published in the last quarter of a century' John BuchanThe perennial classic. Arguably the first spy novel ever written remains one of the finest examples of the genre to this day.

"The first real thriller." --Ken Follett While on a duck-hunting holiday sailing in the Frisian Isles, Carruthers and his friend Davies become suspicious of German naval activity off the North Sea Coast. The pair decide to investigate, are soon embroiled in a world of suspense and intrigue, and set about foiling nothing less than a plot to invade England. Initially published in 1903, this thriller proved a prescient vision of the Anglo-German conflict that was to culminate in World War I. This adventure is now regarded as the first--and one of the best--spy novels ever written, inspiring such later masters of the genre as John Buchan, Ian Fleming, and John le Carré.
