When Caroline learns that British spies may be lurking in Sackets Harbor, she is worried. Then, a long lost friend of Papa’s shows up in town. Papa is delighted to give him a job at Abbott’s Shipyard, but soon, strange things start going wrong. Caroline is sure a spy is making trouble at the yard--but is it one of Abbott’s trusted workers, whom she has known all her life, or could it be Papa’s dear friend? A Looking Back section discusses the role of spies in the War of 1812.
