Louisiana-born Harold "H" Landry made a killing in the oil industry before moving to the United Kingdom and marrying Lucy, a British beauty half his age. But what would motivate Landry to murder his wife? 48 HOURS MYSTERY correspondent Richard Schlesinger updates his November 2011 report on the fairytale romance that ended with Lucy Landry stabbed more than 20 times outside their English manor. Through interviews with Landry, Lucy's son James and others, Schlesinger unravels the complicated world of Harold Landry - including a violent incident in his past - and how a love story went bad in "Murder at the Manor."
