After a heavy rain, Anne discovers that one of the walls in the library basement is crumbling. She asks Alex to evaluate the damage, but while they're examining the hole, they uncover a human skeleton! Anne finds an arrowhead buried with the skeleton, as well as Aunt Edie's bow and arrow hidden nearby. Surely her beloved relative had nothing to do with this mysterious person's death, did she? Anne must dig deep into the library's past in order to learn the truth. Meanwhile, Anne stumbles on a flyer for the church's father-son retreat in Ben's trash and is determined to find a way for him to participate, despite his protests. As she researches Aunt Edie's love of archery, she discovers a new link to her aunt who can help Anne pass on a very special legacy to Ben.
