Dark Invasion

About this book

From A Note to the reader... In the nonfiction spy tale that follows, I tell how a sophisticated foreign intelligence organization launched a covert campaign of terror--bombs, germ warfare, and murder--against an unsuspecting turn-of-the-century America, and how Tunney and his men, at first overwhelmed and overmatched, rose to the challenge of defending the home front. This book is not an attempt to give the reader a comprehensive history of a reluctant America's entry into World War I. Rather, it shares the mysteries Tunney's team confronted and reveals, in their struggle to solve these, a dark and startling corner of the growing drive toward war.
