INTRODUCTION
Espionage has always been to Americans one of the hateful relics of an outworn political system of Europe from which America was fortunately free. We lived in an atmosphere not tainted with dynastic ambitions or internal oppression. We had no secret agents spying and plotting in other countries and were slow to suspect other countries of doing such things here.
The war, however, disillusioned us. We found our soil to be infested with representatives of an unscrupulous Power which did not hesitate to violate our hospitality and break its most sacred pledges in using this country as a base for unneutral plots against France and Great Britain. We soon learned that these plots were directed against us as well. They were only another manifestation of the spirit which led to the open hostility of Germany which forced us into war.
