Super organizer Ellie Avery could really use some Christmas cheer when Gabrielle Matheson, a grinchy professional rival, sets up shop in the same small Georgia town. But before the halls are even halfway decked with holly, someone uses Ellie's terrifically tasteless white elephant swap gift as . . . a murder weapon!
Ellie's now a suspect. Besides playing Mrs. Santa for her Air Force pilot husband and their two kids, shielding her eyes from the garishly over-decorated house down the street, and helping a client who's a hardcore hoarder, Ellie also has to solve this ho-ho-homicide . . . and find a killer who wishes her a very deadly Christmas.
