I enjoyed reading the book. I think it is written perfectly for casual reading. The title is misleading. The book is far too short to be a complete history. However, it is engaging. The story moves along at a brisk pace. There is content that is not commonly repeated in the many other books on the Mafia. That being said, there were some errors; there were questionable declarations; and there were areas that begged for more information.
The short chapters and large pictures make this book more decorative than informative. The writing style errs on the sensational and overly-simplified rather than documented and proven. That makes for easy reading, balancing what is lacks in thoroughness. Smith writes with a casual, almost conversational tone. Another reviewer described the book as a History Channel special. That covers the style perfectly.
The book loosely covers the Mafia in Italy and America between the 1860s and early 2000s by focusing on key individuals. It is not about Prohibition; it is about Al Capone. It is not about the 1990s; it is about Italian Prime Minister Giulio Andreotti. There seems to be more content on Italy than America. Smith focuses on New York with a brief chapter on Al Capone. Smith also has a habit of sensationalizing the mob. The concern is not the discussion of farmers and petty merchants shaking each other down; but rather what juicy stories could be included with the barest documentation? The result is Smith covering the crimes of Michele Sindona and Roberto Calvi; but all the while stressing that they were connected to the Mafia. But the connections are tenuous and their actual involvement with the Mafia is more speculative than proven. Similarly, Smith focuses on Giulio Andreotti way too much in the book, again stressing connections to the Mafia, even though he was not convicted of even Mafia association.
The obvious errors cast suspicion on material that is not so well documented. One error that bugged me was the repeated misspelling of Simone DeCalvacante as "Cavalcante." The claim that Gotti posed for tourists outside the Ravenite Social Club is not entirely out of character for Gotti; but otherwise undocumented. Did US soldiers in WWII award an honorary rank on Calogero Vizzini and call him "affectionately" General Mafia? I am skeptical. Did Lucky Luciano unilaterally determine that heroin processing would go to French gangsters?
There is some good information. Smith spends more time discussing recent developments in Sicily, that are not readily available to American readers. His closing chapters on Bernardo Provenzano revealed that the aging mob boss was facing a coup by Nino Rotolo. Until this book, I was totally unaware of that story. Smith's take on Buscetta's testimony is interesting. He portrays the First Mafia War in the 1960s as a generational conflict rather than an inter-family conflict. Previous writing had described the origin of the conflict as control over the produce markets of Palermo, aggressiveness by the LaBarbera Brothers, as well as narcotics. Here, Smith may be simplifying the story to make is nice, neat, and coherent.
Overall, it is a fascinating casual read even if it lacks depth or references. References or even a bibliography would have been very helpful. I can recommend it for any reader including crime enthusiasts and aficionados. The errors are easy to spot. It provides great fodder for the water cooler. Readers totally unfamiliar with the subject would raise an eyebrow in disbelief at some of the content, so the book does its intended job of offering an overview of the subject and then create discussion topics.
