As Matt pointed out, Eliot Asinof tends to overuse exclamation points, as they seem to be present on almost every page. However, considering what I know about this scandal, the information provided in the book appears to be correct, and it offers a fairly accurate portrayal of the events that occurred before, during, and after the scandal.
My favorite line from the book can be found on page 192: "Reutlinger had seen enough of America to know that the written rules were rigid and righteous, while the real rules were wide open and dirty." I believe this statement holds just as true today as it did back in 1919 - 1920. If we fail to read the signs and make an effort to maintain some semblance of order, our system, as we know it, will completely collapse. Some rules are explicitly written, while others are implied. But if we deliberately choose to ignore the rules, it seems to me that we are being willfully ignorant or perhaps even sociopathic :-).
