Bill Roemer's mistake was inserting himself as a character into "true crime" accounts of the Chicago Outfit. His other mistake was releasing a terrible crime novel (a work of fiction) with the same publisher in which he used real-life Chicago and New York mobsters as characters in the story. I think Roemer's anti-Giancana bias and grudging admiration for Accardo and Joe Bonnano hurts his credibility. But then again, I don't think he invented everything he wrote.

If anyone wants to know how a book about the mafia should be written, they should read Jeff Coen's Family Secrets.
