When a faceless body is found in a car at a remote boat launch, investigators are faced with parallel mysteries: Who is he? Who killed him? And why can’t they find out who owns the car? Major Nicole Brooks juggles surprising conflicts of interest to conduct an already-difficult investigation in what could be the most confounding of her career. As detectives chase clues, Dr. Leslie Wilson’s autopsy finds even more mysteries on the dead man’s skin. But are the strange markings mere curiosities, or vital clues? Margaret Karikas leads a group of journalists and a young intern to pursue the news, sending her own team into more danger. Two mysterious buildings a few miles from the crime scene hide the clues, but are they also hiding the killer? They are determined to find what lies behind the walls. A strange visitor at Rev. Roxanne Clement’s church may be the key, but even what Roxanne knows won’t break the barriers of silence or completely unveil the complexity of secret, sacred oaths.
