Just finished Anthony Destefano's bio of Frank Costello, "Top Hoodlum." Destefano wrote a brilliant bio of Joe Massino. His Costello book isn't quite in the same league. He gives great detail on Costello's personal life and how he built his fortune. But there's practically no detail on how he ran the Luciano Family for 20 years--nothing that shows him as a Don, rather than an enterprising criminal businessman. Still, it's head and shoulders above the usual Mob bios.
