Sarah Ann Hearn, a widow, lived in Trenhorne, between Lewannick and North Hill. She devoted herself to the care of her sick relatives.
Her sister Minnie was a chronic gastric patient. An aunt had passed away a few years earlier, and Minnie’s own demise, when it came, was not unexpected. But then, in 1930, the painful death of a nearby farmer’s wife, Alice Thomas, apparently after consuming Mrs Hearn’s homemade salmon sandwiches, provoked local suspicion.
What had happened to the lonely widow’s supply of arsenic-based weedkiller? Who was Mrs Hearn, really? The strange truth behind the case of the Salmon Sandwiches has finally been unearthed.
