Just finished it. It has some good background on the Patriarcas and bug transcripts from Anguilo's office bug. The FBI's inept attempts at trying to spy on Agiulo are entertaining.

It was published in the late '80s before the truth about Connolly came out. I read the edition released after Black Mass came out (some authors) and even though they noted the FBI's wrongdoings in the intro, it retained the text that still made Connolly and John Morris seem like heroes, that was pretty nauseating.

Pretty good if you don't know much about the Patriarcas, which was informative for me, but otherwise it's your run-of-the-mill "hardworking FBI agents crack scumbag mobsters" book.
