It’s Halloween, and Lee is wrapping up a TV special at Underhill, a haunted house on Bodmin Moor. There’s only one problem – despite its terrible past, this house doesn’t seem to be haunted at all. Not great for the fans of Spirits of Cornwall, but all Lee wants to do is get home to Gideon and Tamsyn in time for their family party. Gid and Zeke are due to pick him up at any minute, so Lee sends his film crew home to enjoy their own Halloween plans .

The moment he’s alone, everything changes. When Gideon and Zeke arrive, they find the house deserted and dark. Zeke thinks Lee must have left with the film crew, but Gid’s instincts tell him otherwise.

The policeman and the preacher must set aside their differences and pool their gifts to pick up Lee’s trail. Will they be in time to save him from the ghosts and strange forces at work in Underhill House?
