What happens when German spies collaborate to unleash a campaign of terror upon America at the start of World War I?

In Dark Invasion: 1915, a New York City policeman uncovers a German plot to sabotage ships, factories, and even J.P Morgan himself. Howard Blum tells a gripping, true story of espionage and terror on American soil during World War I and the Irish cop who hunted for the conspirators among a population of more than 8 million Germans.

Blum is the author of The New York Times bestseller and Edgar Award-winning American Lightning. He is a contributing editor at Vanity Fair and has twice been nominated for the Pulitzer Prize for investigative reporting.
