On February 26, 1986, Mafia underboss Gennaro Angiulo was convicted of racketeering and sentenced to forty-five years in jail. In The Underboss, bestselling authors Dick Lehr and Gerard O'Neill inform the story of the autumn of the home of Angiulo. The Federal Bureau of Investigation, aided partially by the Irish Mob's Whitey Bulger, entered the Boston Mafia's headquarters in Boston's North Finish early one morning in 1981 and commenced to compile the proof that may result in the whole higher tier of one of the vital worthwhile and ruthless felony enterprises in America. Initially revealed in hardback by St. Martin's in 1989, The Underboss turned a nationwide bestseller. Data uncovered through the course of Lehr and O'Neill's Black Mass investigations provides new dimensions to the story and the authors embody this new material-including Whitey Bulger's cagey manipulation of the FBI-in The Underboss's revised textual content and in a brand new preface and afterword.
