The Eagle's Eye

The Eagle's Eye, written by Courtney Ryley Cooper and published in 1919, is a historical novel that delves into the espionage activities of the Imperial German government in the United States during World War I. The narrative follows the efforts of American Secret Service operatives, particularly Harrison Grant, as they attempt to thwart German spies, including Count Johann von Bernstorff, who are plotting sabotage against American interests. The book is notable for its detailed portrayal of real espionage events, including the bombing of the Lusitania, and is based on facts provided by William J. Flynn, former chief of the U.S. Secret Service.
