It's the week before Thanksgiving in River Heights—time for turkey! But this year it looks less like turkey time and more like turkey trouble! When new girl Riley MacArthur brings a real live turkey in for show-and-tell, Nancy's class is excited. Nancy has never seen a live turkey before—and she's never heard of one named Martin. But when Martin ends up missing, Riley needs Nancy to track him down.

Who would steal a turkey? And will Nancy be able to catch the turkey-snatcher with no clues—or feathers—in sight?
