Behind Mansion Walls

Many people are jealous of others who live in mansions, but if they knew the inside story, people might not be so green with envy. Hosted by journalist Christopher Mason -- a longtime chronicler of high society and its duplicitous affairs -- "Behind Mansion Walls" describes what happens when family dynasties implode, high-stakes divorces end in bloodshed and rich decadence turns to death. The docuseries details the criminal investigations of oil tycoons, real estate moguls, self-made billionaires and privileged heiresses, aided by expert testimony, stylized re-creations, and narration from the victim's first-person perspective.
