On a November night in 1997, Galway based taxi driver Eileen Costello O'Shaughnessy left Galway city on what appeared to be just another fare. But when the ever reliable Eileen failed to meet her boss later that night, it was clear that something was not right. Over that night and into the morning an extensive search for Eileen took place.
The following day, Eileen's body was found at a place known as Tinkers Lane outside of Galway city.
Nearly thirty years later, despite numerous appeals, witness sightings and extensive Garda investigations, her killer has never been identified.

In the quiet town of Circleville, a series of anonymous letters were posted. The letters were full of accusations, threats, and information about secret relationships.
What started as a disturbing act of harassment soon escalated into something far more sinister. That eventually destroyed the social fabric of a peaceful mid-western town.
But even after an arrest and conviction, the letters continued. Which only added to the mystery and speculation.
In this episode of The Cliff’s Edge Podcast, I’m joined by a special guest Kevin to explore one of the most infamous cases of poison pen in American history.
