I've read this and also the new Mafia Prince book about Phil Leonetti. I thought this was better.

Although Leonetti has some disparaging things to say about Nicky the crow in his book, it just seems to me like Nicky was more involved in what was going on in South Philly during the 1980's while Phil was more out of the loop.

Nicky the crow is a self confessed con artist however I did find this to be pretty believable and is very much worth reading.
