Secret Armies

The material in this small volume just barely scratches the surface of a problem which is becoming increasingly grave: the activities of Nazi agents in the United States, Mexico, and Central America. During the past five years I have observed some of them, watching the original, crudely organized and directed propaganda machine develop, grow and leave an influence far wider than most people seem to realize. What at first appeared to be merely a distasteful attempt by Nazi Government officials at direct interference in the affairs of the American people and their Government, has now assumed the more sinister aspect of also seeking American naval and military secrets.
