The Pinkerton Files is based on the new audio series starring Battlestar Galactica's Michael Hogan. It sets the real cases of America' s first private detective in a world of radical inventions driving a bitterly divided nation toward civil war.

Agency founder Allan Pinkerton senses a conspiracy mounting against him, his sons and his operatives. Every step they take toward solving three seemingly disconnected cases draws them further into a conflict that will be their downfall. If Allan allows them to become embroiled in the war, they will never find their way out.

Lincoln and the Golden Circle launches as a simple assignment to protect a rail line from sabotage but explodes when one of Allan' s agents is murdered, his son is arrested and his protege is wickedly assaulted. With police descending on his headquarters, Allan must choose whether to commit his detectives to a death defying sprint in a final attempt to save the President' s life.
