In the late 1970s, the peaceful, small town community of Circleville, OH, was shaken when individuals began receiving strange letters.  They all came in the mail with absent or fake return addresses, and were postmarked from Columbus, OH, 25 miles north of Circleville.  The letters were handwritten in strange block letters and contained details about the recipients.  Over 1000 letters were sent, accusing neighbors of affairs, exposing private lives, and threatening violence if confessions weren’t made.  And whoever was behind them seemed to know everything including intimate details no outsider should have known.  Then, things escalated.  One victim died under suspicious circumstances while confronting the writer.  Another was set up with a booby trap that was supposed to kill her on contact.  What started as anonymous harassment was now something far darker and far more deadly.  But here’s where the mystery deepens.  A suspect was caught. A trial was held.  A man was sent to prison.  Case closed… right?  Not even close.  Because even after the conviction, the letters didn’t stop.  So who was really behind the Circleville letters?  Today we’re talking about a wild story involving secrets, paranoia, and the terrifying idea that someone out there might know you better than you know yourself.
