Brooklyn. The most populous borough in New York City. Birthplace of the Dodgers, Sweet'n Low, and Season 21 of "The Real World." With more than 400 years under its belt, the borough is filled with a history of both sweet and savory moments. It's hard to imagine Brooklyn as anything other than a concrete jungle. Who would guess that that first battle of the Revolutionary War was fought here? Or that the world's oldest subway is hidden beneath the streets of Boerum Hill? Or how an airplane fell from the sky and landed in the middle of the street in Park Slope? Hundreds of people pass by the Prison Ship Martyrs Monument in Fort Greene Park everyday. Virtually no one stops to read the plaque. If they did, they would learn that it is actually a grave, holding up to 15,000 bodies. Author Allison Huntington Chase, Brooklyn's own Madame Morbid, takes readers on a journey beyond the brownstones, to discover the hidden, macabre and bizarre throughout Brooklyn history.
