This is police official Rick Porrello's first book, and was inspired by his family's long refusal to discuss the Porrello family's involvement in organized crime in Cleveland. Porrello's writing style tends to be somewhat clumsy, and like a first-time author without much training he litters his prose with cliches, over-used metaphors, and the occasional serious historical error (like assuming what a long-dead person "must have thought").
The book is an interesting look at the Cleveland Mafia -- the organized criminal organization founded by Sicilians and Italians in Cleveland around 1900. There are no citations here, no references, no bibliography. But from my own research, it seems apparent that Porrello primarily relied on newspaper articles in The Plain Dealer newspaper for his information. That's disappointing, as one of the reasons people read Porrello's book is to try to gain some inside dope from the Porrello family. There just isn't any.
Porrello offers extremely little in the way of any contextual information for the development of the mafia or other organized crime in Cleveland. Although he's somewhat better about the mafia's role in Prohibition, even then there's not much to help the reader understand the impact of the mafia on Cleveland, the extent of its crimes, or exactly what it is that the Porrello brothers did every day.
Roughly a third of the book focuses on the vicious blood feud between the Lonardo and Porrello families. The feud led to the death of three members of the Lonardo family and four members of the Porrello family, including Rick Porrello's own grandfather. By the time the blood-feud ended in 1932, both families had been decimated and Frank Milano had seized control of the Cleveland mafia.
The latter part of the book covers the Cleveland Mafia briefly over the next 60 years, and the effect of the blood-feud on the Porrello family. Much of this is glossed, however, almost like a short essay that covers a few "greatest hits" (like the Apalachin Conference, the betrayal by Angelo Lonardo, and the war with Danny Greene).
Overall, however, this isn't a bad book. It's just not very good. For a casual reader, it's probably good enough. For anyone expecting a good history of the Cleveland mafia, the book is a let-down. It doesn't focus on the broader picture and on very few of the other major figures in the Cleveland mafia (like important soldiers, capos, or configlieres). There are also a few factual errors in the book. It seems these are drawn from newspaper accounts (which, in the 1910s, 1920s, and 1930s weren't too particular about accuracy) and some general crime sources which weren't verified. The work is short on details, too, which is incredibly frustrating.
