Murder With All the Trimmings
Josie Marcus, Mystery ShoppereBook - 2008
Mystery shopper Josie Marcus doesn't get the appeal of the year-round Christmas shop. But when three such holiday houses pop up within two blocks, she's assigned to rate them anonymously. Easy enough, Josie thinks, until she realizes that shoppers at one store are finding a strange, even deadly, secret ingredient in their holiday cake. And Josie must get to the bottom of it all before someone else becomes a Christmas spirit.
