The Last Archive is a show from Pushkin Industries about the history of truth, and the historical context for our current fake news, post-truth moment.

It’s a show about how we know what we know, and why it seems, these days, as if we don’t know anything at all anymore. The show is driven by host Jill Lepore’s work as a historian, uncovering the secrets of the past the way a detective might.

On this episode, The Clue of the Blue Bottle, Jill tells the story of a Spring day in 1919, when a woman’s body was found bound, gagged, and strangled in a garden in Barre, Vermont. Who was she? Who killed her? Jill tries to solve the cold case—reopening a century-old murder investigation—as a way to uncover the history of evidence itself.
