Almost one hundred forty years after the vicious and unsolved murder of the beautiful 17-year-old daughter of a well-to-do local family, a seasoned prosecutor and detective of the Monroe County Pennsylvania District Attorney's Office team up to solve this coldest of cases. By using the techniques, methods, and insights acquired over the course of their careers they pursue the crime in all its details, recognizing the limitations and failings of the original investigators, uncovering leads long ago forgotten, and using the passage of the years to connect suspects to the crime. Their mission is to fulfill a centuries old mandate issued by a long forgotten grand jury directing their predecessors to 'use all resources to ferret out the murder of Etna Bittenbender'. Their journey through the darkest inner recesses of the human soul gives form and shape to an innocent life brutally snuffed out and of a depraved crime both of which had been reduced to nothing more than a dim memory.
