My Life as an Enforcer for Whitey Bulger and the Boston Irish Mob, by Edward J. McKenzie and Phyllis Karas. For decades, Edward J. MacKenzie, Jr. (a.k.a. Eddie Mac) was a drug dealer, enforcer, and key associate of Bulger (on the lam as this book was published). Mac's first-person account of those years is rife with more gory details per page than the entire last season of The Sopranos. 2004.
