The origins of the archetypical, modern gangster can be traced to 1920s America, when Prohibition turned street-corner hoodlums into rich and powerful businessmen. But today's highly organised and ferociously protective gangs are prevalent throughout the world. This book delves into the darkest depths of the underworld, from mobsters in America to Hells Angels in Germany to child armies in Africa...not forgetting the monsters on our own doorstep.
