On a spring day in 1919, a woman’s body was found bound, gagged, and strangled in a garden in Barre, Vermont. Who was she? Who killed her? In this episode, we try to solve a cold case - reopening a century-old murder investigation - as a way to uncover the history of evidence itself. What is a clue? What is a fact? What is a mystery? We put the pieces of the puzzle together: photographs, newspaper articles, a private eye’s notebook, the trial record and, last but not least, a trip to the scene of the crime.
