Dead to the World — Susan Rogers Cooper

E.J. has a surprise twentieth wedding anniversary present for Willis -- a weekend away in the Texas hills. She's found the perfect Bed and Breakfast -- the Bishop's Inn in the quaint town of Peaceful. Unfortunately, they've barely arrived before the inn's troubled elderly owner, Carrie Marie Hutchins, confides in them about a harrowing event from her childhood involving her dead father ... and his spirit, which won't go away... E.J. has little time to digest Carrie's tales of strange goings-on: screaming, the guests' suitcases slashed, underwear hanging from a light fixture, before a further bizarre twist occurs: Humphrey Hammerschultz and Diamond Lovesy, self-proclaimed ‘psychic detectives', suddenly turn up at Carrie's door. And when E.J. discovers a body, she determines to find out what's really going on in this not-so-peaceful town.
