Exploring Symbols and Personal 'Poisons'

Brian Cox and Robin Ince delve into the murky world of historical poisonings. Joining them to add their drops of killer insight are comedian Hugh Dennis, chemist Andrea Sella and Agatha Christie aficionado and former chemist Kathryn Harkup. They find out just how easy poison was to get your hands on and how people literally got away with murder until chemists developed tests for substances like arsenic. Bottles of deadly substances are passed around our expert panel with some trepidation and we learn how seemingly innocuous garden plants can be deadly in the wrong hands.
