How Sidney Korshak and His Criminal Associates Became America's Hidden Power Brokers

An investigative narrative that traces the rise of Sidney Korshak, a shadowy fixer who used legal cover and high‑level connections to knit together organized crime, labor unions, Hollywood and corporate America; the book shows how Korshak and a small circle of associates quietly shaped Las Vegas and major business deals, protected mob interests, brokered back‑room arrangements, and blurred the line between legitimate institutions and criminal influence, revealing a hidden network of power that affected politics and the economy in mid‑20th‑century America.
