It's Hart to Hart via HGTV on All Hallows' Eve, as partners and home renovation hosts Peter Penwell and JP Broadway try not to flip when their newest fixer-upper is rumored to be a haunted house . . . Kicking off season three of their hit reality TV show Domestic Partners is a home renovation project with an irresistible hook. Woods Hall is a lavish 1913 manor home in the Detroit suburb of Pleasant Woods, once belonging to the town’s founding family. It also comes with its own ghost.Twenty-five years ago during a Halloween night party, automotive heiress and beauty queen Emma Wheeler-Woods, wearing a white Princess Diana wedding gown as a costume, fell from a third-floor balcony to her death. Or was she pushed?Fiona Forrest recently inherited the home after learning she was Emma’s daughter, and she and her fiancé have hired the Domestic Partners to restore the family property to its original splendor. But ghostly sightings, injured crew, secret passageways, locked rooms, and sabotage beg the question: Is the place actually haunted? And perhaps more practically, was Fiona’s mother murdered?Hustling to have work finished in time to shoot the finale on Halloween—the anniversary of Emma’s mysterious death—do Peter and JP have a ghost of a chance of also solving a cold case from a quarter of a century ago before someone else takes a fall?
