A few organized crime related books I've been reading as of late include: Off Color: The Violent History of Detroit's Notorious Purple Gang by Daniel Waugh. I'm only 90 pages into Off Color. So far its been a fascinating book on Detroit's Purple Gang. Another book I'm reading on my Kindle Fire is The Mob and the City: The Hidden History of How the Mafia Captured New York by Alexander Hortis. This book is providing fresh insight into the inner workings of organized crime in NYC.
