Ovid Demaris was ahead of his time writing about organized crime. The Green Felt Jungle by Demaris is required reading on organized crime's influence in Las Vegas. Not directly related to your topic, Captive City, also by Demaris and published in the late 1960's, remains one of the best early books on organized crime in Chicago.
