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.

In December 1926, Agatha Christie—already one of the world’s most celebrated mystery writers—vanished without a trace. Her abandoned car, a nationwide manhunt, a false identity, and a hotel registration under her husband’s mistress’s name turned Britain upside down for 11 unforgettable days.

When Christie was finally found alive, nothing about her story added up… and she never explained what happened.

Was it amnesia? A staged escape? A psychological break? Or the greatest mystery she ever wrote?

This episode of The Enigma Files unpacks the clues, contradictions, and theories behind one of history’s most baffling disappearances.
