Maggie Crozat is back home in bayou country during the most magical time of the year. In Pelican, Louisiana, Christmastime is a season of giant bonfires on the levee, zydeco carols, and pots of gumbo. Except, this year, the Grinch has come to stay at the family-run Crozat Plantation B&B. When he floods travel websites with vicious reviews, Maggie thinks she's identified him as rival businessman Donald Baxter. That is, until he's found stabbed to death at Maggie's workplace.

The sleigh bells are jingling, and the clock is ticking for Maggie and Rufus, who must catch the killer, or it will be the opposite of a Joyeux No l.
