While writing about the many discrepancies and contradictions in the life histories of 10 infamous New York mob bosses of the 20th century, the author notes which facts rest on popular tales or theories, and often gives several versions of the same event. The biographies describe the early years of each man, chart his rise to prominence within the mob, provide reactions from those who knew him, and chronicle the last years of his life. Each biography is illustrated with a picture of its subject and concludes with a listing of print and electronic resources. Two of those profiled, Joe Adonis and Albert Anastasia, have not had any biographies published about them until now. A 35-page timeline from 1882 to 1976 allows readers to track the birth, death, and important events in the life of each mobster. May has written many articles on organized crime.
