I was looking forward to a well researched and engaging narrative history of the Mafia, but what became clear quite quickly is that Al Cimino is not that kind of writer and this book would be nothing like the standard true crime books I like.
Cimino's writing style is the main issue. He tells the history of the mob in the quickest, most jarring way possible. New names, dates, places, events are thrown at the reader every other sentence. It makes for an incredibly disjointed, jarring, and unpleasant reading experience. I understand that there is likely a lot of history and notable names to get through in a book about the history of the mafia but there are way more effective ways to tackle that issue than just throwing every name involved on paper, only to drop them in the narrative a few paragraphs later when they were killed off.
I decided to DNF this book during the chapter that was allegedly about Al Capone. I was already frustrated with the reading experience of Mafia Crimes but when the chapter on Al Capone wandered away from talking about Capone himself relatively quickly and instead engaged with the development of Chicago mafia wars that would eventually place Capone in power, I just couldn't continue. I had forgotten basically every person and small killing in the first few chapters except for the Bananas guy and the NYPD officer who was killed in Siciliy. I was retaining no information while reading this book. I wasn't learning anything. At the pace this book is written in, there was a good chance I would not learn anything more substantial.
There are very likely many other books on the history of American organized crime and Italian organized crime than this.
