In The Day Wall Street Exploded, Beverly Gage tells the story of a once infamous but now largely forgotten terrorist attack. Based on thousands of pages of Bureau of Investigation reports, this historical detective saga traces the four-year hunt for the perpetrators, a worldwide effort that spread as far as Italy and the new Soviet nation. It also takes readers back into the decades-long but little-known history of homegrown terrorism that shaped American society a century ago. The book delves into the lives of victims, suspects, and investigators: world banking power J.P. Morgan, Jr.; labor radical "Big Bill" Haywood; anarchist firebrands Emma Goldman and Luigi Galleani; "America's Sherlock Holmes," William J. Burns; even a young J. Edgar Hoover.
