The people of mid-Ohio's Pleasant Valley went on with their normal lives that cold and rainy spring of 1896, not knowing that young Ceely Rose was brooding. She'd been told to forget her obsession with handsome Guy Berry. She'd been told about the danger of Rough-on-Rats poison. She'd heard about murdering those who stand in the way of love. By the time she was done, her family would be dead and others threatened. Later, the place where these crimes took place became Malabar Farm, the estate of Pulitzer Prize-winning author and conservationist Louis Bromfield. Historian, playwright, and storyteller Mark Sebastian Jordan examines the story of the Poisoner of Pleasant Valley, Ceely Rose, and how it has resonated throughout the years.
