Traitor in the Shipyard: A Caroline Mystery (American Girl Mysteries (Quality))
I'm excited about the 7th Caroline book,Traitor in the Shipyard.While  researching and writing the first six Caroline Abbott books, I started a  file of ideas for a mystery. Caroline lives right on the border between  the United States and British territory during the War of 1812, and people in her town worry about traitors causing trouble. Real incidents inspired this mystery, and I hope it keeps you guessing!
