When Trent Sanders says on television that Selina James is delusional for believing she speaks to ghosts, he finds himself in hot water. Selina's mother challenges him to spend two weeks in a haunted hotel that has been closed down for years with Selina to prove that ghosts really exist. He, of course, agrees to the challenge as part of his crusade against fraudsters after a fake psychic almost ruined his family following the death of his father.
Trent and Selina initially find themselves cleaning some of the rooms to make them habitable, then have to fend off visits from various family members and eventually settle down to getting to know each other. Trent decides to use the time to write an exposť of frauds like Selina; she spends the first few days getting to know the two resident ghosts, Wesley the cowboy and his girlfriend, Dixie.
Most of Double Dating with the Dead is taken up with the ghosts doing various things like dropping bags of sugar and pinching Trent's backside and Trent thinking Selina's doing it. Their conversation seems to revolve around Selina being a fraud and Trent not being open to supernatural things, with significant doses of sexual flirting as well. The ghosts give them disturbed sleep with fantasies about each other, but there's not actually all that much plot to carry the book. Another newspaper woman, Barbara, makes a brief appearance but doesn't really add much to the story. The basic premise of the story is a giving-into-lust tale with the ghost element helping to fill in the rest of the events. Characterization isn't very strong, and the relationship between the two main characters seems far more lust-based than anything else. It's a reasonable enough book as a light read but ultimately unsatisfying.
