When Cora Thorogood embarks on a journey to help her grandmother and her old school chum, she has no idea that it will lead to the dark secrets of a murder that occurred fifty years ago. Adelaide, a once vibrant girl, vanished without a trace, and now Cora, along with Elizabeth, Cybil, and Molly, must piece together the cryptic clues that connect the past to the present. As they search through forgotten cemeteries, uncover old tombstones, and dig through historical records, the women discover that the quiet town holds more secrets than they could have ever imagined. With every step closer to the truth, they find themselves tangled in a web of deception, fear, and possibly even more death. Will they be able to solve the mystery of Adelaide's disappearance before the shadows of the past reach out to claim them as well?
