 The book details the rise and fall of 19th century gangs in New York City, prior to the domination of the Italian-American Mafia during Prohibition in the 1920s.Focusing on the saloon halls, gambling dens, and winding alleys of the Bowery and the Five Points district of Lower Manhattan, the book evokes the destitution and violence of a turbulent era, when colorfully named criminals like "Dandy" Johnny Dolan, William Poole (also known as Bill the Butcher), and Hell-Cat Maggie lurked in the shadows, and infamous gangs including the Plug Uglies, Dead Rabbits, and Bowery Boys ruled the streets.It includes a rogues' gallery of prostitutes, pimps, poisoners, pickpockets, murderers, and thieves.
