Yes, it's good. I think that the other book To Drop a Dime had a little more detail, but I read it so long ago I can't remember. But Deal tells the same story of how Ira Pecznick and John Tully got to know one of the Campisis in jail, and began to work with them when they got out. It goes through the murders, Louie Luciano, Candido Trueba, William Kimbrough. And Gerald Mass who was a truly innocent victim.
