The Case of the Missing Elf [a Diz and Dee mystery]

Christmas comes early for private investigator Dee and her partner, the grumpy but drop-dead-gorgeous elf Dizzy G, when Santa's elves hire Diz and Dee to find Santa's missing stand in. Santa's taken a sabbatical, and only one elf at the North Pole can fill the big man’s shoes. An elf who’d rather compete in professional food-eating contests than spend one more holiday in Santa’s sleigh.
