In the quiet farm town of Circleville, Ohio, secrets once lived safely behind closed doors — until anonymous letters began arriving in the 1970s, each one exposing affairs, crimes, and private lives with terrifying precision. No return address. No mercy.

Then one of the targets, Ron Gillispie, dies under suspicious circumstances. A booby-trapped gun appears years later. A man is imprisoned. And yet… the letters continue.

In this slow-burn, cinematic episode, Matt and Gavin unravel one of America’s strangest and most unsettling unsolved mysteries — a case where fear arrived daily by mail, suspects hid in plain sight, and the truth may have been buried deeper than the letters ever revealed.

This is the story of a town that read its own secrets… and never recovered from what it learned.
