The novel introduces forensic archaeologist Dr. Ruth Galloway, a quirky and solitary academic living on the remote Norfolk salt marshes. She is called in by DCI Harry Nelson to examine skeletal remains found near a prehistoric henge, which are suspected to be those of Lucy Downey, a young girl who disappeared ten years prior. As Ruth and Nelson investigate, they are drawn into a complex case involving ritual sacrifice, ancient history, and a killer who taunts Nelson with cryptic notes. The case becomes personal and dangerous for Ruth when another child goes missing, forcing her to confront the chilling truths hidden within the landscape and its past.
