On 5 November 1878, Ella Hearn was shot in her family home in Pocomoke City, Maryland. The accused was Lillian Duer-her closest companion. What followed was a month-long vigil, a fugitive escape, a coroner's inquest, and a sensational trial in Snow Hill. Based on surviving 19th-century reporting, The Duer-Hearn Case reveals a story of obsession, coercive control, and a justice system shaped by gender and class.
