WHO: Richard Schlesinger reports the rags-to-riches fairytale that would have a gruesome ending when H’s wife Lucy Landry was found dead, violently stabbed more than 20 times. 48 HOURS MYSTERY unwinds the complicated past of a man known for his big bucks – and an even bigger personality –  including an exclusive interview with H, and James McAllister, Lucy’s son.
