On a cold December evening in 1992, the peaceful and affluent suburb of Malahide, North Dublin, was shattered by a brutal and baffling crime. Grace Livingstone, a 56-year-old wife, mother, and respected member of the local community, was executed in her own bedroom with a single shotgun blast to the back of the head. Her killer vanished without a trace. Despite early suspicions pointing to her husband, a high-ranking tax investigator who owned the very weapon that was used, no one was ever charged. No motive was ever confirmed. More than thirty years later, the murder of Grace Livingstone remains one of Ireland’s most unsettling and high-profile unsolved cases—an enduring cold case marked by missteps, suspicion, and controversy. What follows is the Radio Espial TIMELINE—a gripping, detailed reconstruction of a murder that stunned a nation. This is not just a cold case... it's a story of how truth and a murderer can vanish in plain sight.
