Sponsored by the Reverend Robert Gordon, Louisa quickly discovers he is hiding a tragic secret. Louisa irritates, intrigues, and charms Robert, soon becoming an indispensable part of his household. Trouble begins to brew when Friedrich Mueller, a prominent resident of Copper Springs and avid Nazi sympathizer, ferrets out Louisa's background.

Soon Louisa is once again running for her life. Can she outfox a fox like Mueller? Or will she be sent back to Germany as a hostage exchange, facing certain death?
