From the publisher
From Emmy and Peabody Award–winning journalist Mariana van Zeller comes THE HIDDEN THIRD, a weekly dive into the underground markets that quietly power a third of the global economy. Every episode Mariana sits down with people who know these worlds firsthand - the hustlers, smugglers, scammers, kingpins, and those trying to shut them down. The series reveals how they function, why they endure, and the profound ways they impact us all. New episodes drop every Wednesday wherever you get your podcasts. The Hidden Third is a co-production of Muck Media and The Roost Podcast Network.
