Joining Bloomberg This Weekend is Best Selling Author Patrick Radden Keefe to discuss his new book 'London Falling,' which explores the mysterious 2019 death of 19-year-old Zac Brettler, whose parents discovered after his death that he had been posing as the son of a Russian oligarch. Keefe explains to Christina Ruffini that the story examines London’s influx of extreme wealth and social media-fueled status anxiety while tracing a family’s effort to understand the secret life their son had built.
