GUY GAUNT's infiltration of America's leadership changed the course of history. When the Great War began he was the British naval attachA(C) in Washington, beached for recklessness at sea. Taking over a network of disaffected immigrants he thwarted all efforts by the powerful German-American establishment in the United States to stop America from supporting the Allies. The exposure of a sinister German underground showed President Woodrow Wilson that America could not remain neutral. The Foreign Office never forgave him for outclassing its fledgling Secret Service.
