For a few years in the 1840s, Essex was notorious in the minds of Victorians as a place where women stalked the winding country lanes looking for their next victim to poison with arsenic. It s a terrible image and also one that doesn t seem to have much basis in truth but this was a time of great anxiety. The 1840s were also known as the hungry 40s, when crop failures pushed up food prices and there was popular unrest across Europe. The decade culminated in a cholera epidemic in which tens of thousands of people in the British Isles died. It is perhaps no surprise that people living through that troubled decade were captivated by the stories of the poisoners: that death was down to white powder and the evil intentions of the human heart. Sarah Chesham, Mary May and Hannah Southgate are the protagonists of this tale of how rural Essex, in a country saturated with arsenic, was touched by the tumultuous 1840s."
