There were a couple of Costello books written in the 70's that are supposed to be good. One was written by his lawyer so I imagine there's a great personal account of him but I'm sure it's also sympathetic and perhaps in denial of a lot of his criminal past. Then there was another written by a journalist or something that supposedly lays out all the facts. I believe they're both out of print so you'd be looking at old copies from amazon. I'm pretty sure ensuing Costello books just use recycled info from these two books.

"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
