Christina, Grant, Mimi and Papa fly the Mystery Girl to Hershey, Pennsylvania just in time for the 100th anniversary of the famous candy company. Their plans are to tour the chocolate-scented town (with the Hershey Kisses streetlights!) and eat chocolate, chocolate, chocolate. But when silver dollars go missing, the mystery family goes into action to save the day! Well, hopefully! Christina is excited about the research, Grant has a tummy ache (wonder why?) And, Mimi won't go near a scale! Join the fun-it's a real treat of a mystery!

LOOK what's in this mystery - people, places, history, and more!
