Buried Face Down

When archaeologists excavated an Indian village in a farmer's field along a river in the Appalachian Mountains of West Virginia, they made a startling discovery. Among the buried remains of ancient American natives, was found the skeleton of a man who had been bludgeoned to death and interred face down sometime in the early nineteen-hundreds.
At about the time of this gruesome discovery, Jenny Franklin, a student at State College, went missing. As far as everyone knew, she was a happy, studious individual who was majoring in sociology. One day she was there, the next, she was gone without a trace.
Professor Jimmy Houston and his friend, Sam Miller, were asked by the dean of the college to investigate Jenny's disappearance. What fate had befallen her? Was she still alive? Was there a connection between Jenny's disappearance and the face down burial? Jimmy and Sam wouldn't rest until they solved this mystery.
