When anthropology professor Luke Littlefield receives an anonymous grant to run a summer enrichment course at an old Shaker Village in Maine, he jumps at the chance. Things are going along smoothly until a visitor is found dead. Luke and his partner Bryan are pulled into a mystery that seems to have no solution. The murder appears to echo a murder that took place some one hundred and seventy years before. Was it a copy cat killing, or was it just a coincidence? But there’s more going on than just murder and Luke and Bryan once again find themselves working with a federal agent to solve more than one crime.
