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?
