Organized crime and street gangs were originally strongly divided along ethnic lines, but into the 1930s, those lines began to blur, especially between the Italian and Jewish gangsters. In this bonus episode, Mafia explores how this change came about, and highlights the prolific Jews who ran the underground world: Arnold Rothstein, Meyer Lanksy, and Bugsy Siegel.   Our sponsor for this episode is [_Button Man_ by Andrew Gross](http://www.andrewgrossbooks.com/button-man/) from [St. Martin's Press](https://us.macmillan.com/smp/).   Mafia's theme is "Spellbound Hell" by [Damiano Baldoni](damianobaldoni.altervista.org).
