The discovery of a booby-trapped sign turned anonymous harassment into attempted murder — and forced authorities to finally act.

In Part Two of The Circleville Letters, the investigation closes in on a suspect from inside the victim’s own family. A gun is traced. A man is convicted. And Circleville is told the mystery has been solved.

But then the impossible happens.

The letters continue — even while the accused sits behind bars.

Was the wrong person convicted?
Was there more than one writer?
Or was the truth buried to protect something far more unsettling?

Part Two examines the arrest, the evidence, the letters sent during imprisonment, and the theories that still haunt Circleville decades later.

This is where the mystery refuses to end.

In 1976, a quiet Ohio town was invaded by anonymous letters that knew far too much. They accused neighbors of secret affairs, threatened public exposure, and revealed intimate details no outsider should have known.

As the letters spread, fear took hold of Circleville. Trust collapsed. Mailboxes became weapons. And when a local husband died under mysterious circumstances, many began to wonder if the writer was capable of more than words.

Part One traces the origins of the Circleville Letters — from the first accusation to the moment the case crossed a terrifying line, ending with the discovery of a booby-trapped sign that changed everything.

This is the beginning of one of America’s most unsettling unsolved mysteries

In November 1912, Chicago waited for the arrival of the “Christmas Tree Ship”—the Rouse Simmons, captained by Herman Schuenemann, known as Captain Santa. Laden with thousands of trees, the schooner was spotted flying a distress flag off Wisconsin… and then vanished on Lake Michigan. In this episode of The Enigma Files, we follow the final voyage, the clues that washed ashore, and the facts behind the legend.
