While researching her latest novel, Jessica almost becomes a casualty in the bombing of a jewelry store. It later turns out that the store's owner has been murdered and the priceless Queen of Tara tiara has been stolen. Forming an uneasy alliance with a pair of wisecracking "Cagney and Lacey" style female cops, Jessica follows the trail of clues to the home of a famously reclusive actress named Siobhan O'Dea.

After Frank's old Army buddy convinces Jessica to visit his ranch on her way back to Cabot Cove, a psychic's dire predictions put a large damper on party festivities when he predicts that the daughter-in-law of Jessica's host will die in a fiery death. However, Jessica soon discovers that the psychic and the intended victim has a past that can't be overlooked, especially after a murder does take place.
