The Mistletoe Mystery by Nita Prose

 Mistletoe is a holiday novella featuring Molly the Maid and the regular cast of characters from the fancy hotel where she works. It's Christmastime and Molly is wondering why her beloved boyfriend Juan is acting so oddly. She keeps seeing him in places he wouldn't ordinarily be and he won't explain. She's beginning to think their romance is over. But Juan has a Christmas surprise in mind.

It's a charming addition to this highly readable series.
