This episode investigates the unsolved murder of Arthur Denton, exploring the contradictions and strange behaviors surrounding the case.

In the early morning hours of August 18, 1991, police are called to a quiet home on Middle Mount Vernon Road near Timber Lake in Posey County, Indiana. Inside, they find retired attorney Arthur Denton dead.
