In Rudolph, New York, it's Christmastime all year long. But this December, while the snow-lined streets seem merry and bright, a murder is about to ruin everyone's holiday cheer in the first Year-Round Christmas Mystery.
As the owner of Mrs. Claus's Treasures, Merry Wilkinson knows how to decorate homes for the holidays. That's why she thinks her float in the semi-annual Santa Claus parade is a shoe-in for best in show. But when the tractor pulling Merry's float is sabotaged, she has to face facts: there's a Scrooge in Christmas Town.
Merry isn't ready to point fingers, especially with a journalist in town writing a puff piece about Rudolph's Christmas spirit. But when she stumbles upon the reporter's body on a late night dog walk—and police suspect he was poisoned by a gingerbread cookie crafted by her best friend, Vicky—Merry will have to put down the jingle bells and figure out who's really been grinching about town, before Vicky ends up on Santa's naughty list . . .
