On a historic Fredericksburg street, Holly Oak stands in quiet elegance. The cannonball wedged between stone and timber is a silent reminder of what the house endured in the Civil War. When Marielle Bishop marries into the Holly Oak family, she soon hears rumors that the ghost of Susannah Page, a Yankee spy, haunts the halls and she uncovers letters written during the Civil War. Adelaide, 83, who also lives there says it’s not her great-grandmother who is the ghost, but the house itself.
