Files leaked from Dubai reveal how Dr Ruja stashed millions in the emirate and struck up a relationship with a mysterious sheikh. Then, a careless selfie leads the podcast to a mansion in an exclusive gated community. As the FBI steps up its search, new information surfaces about Dr Ruja’s disappearance from an unlikely source.
