'Tis the season for sleuthing when secret shopper Josie Marcus's ex falls victim to a festive fiend…

Josie's latest mystery shopper report won't help business at Naughty or Nice, Maplewood's raunchy year-round Christmas store. But she can't worry about work when her ex-dealer, ex-convict, ex-boyfriend, Nate Weekler, just came home for the holidays, prepared to fight Josie for custody of their daughter.
 
Josie wishes he'd catch the next sleigh out of town, but instead, Nate is poisoned…and suddenly Josie is a person of interest.
With Nate's criminal past, he'd never make Santa's "Nice" column, but his own list of enemies also includes plenty of "Naughties" who might want him dead. Josie will need her team of little helpers to wrap up this case, before the killer commits another holiday homicide.
