Fresh doubt has been cast on a 100-year-old murder conviction that saw a solicitor sent to the gallows for poisoning his wife with arsenic.
On 22 February 1921, Kitty Armstrong died at their home in Hay-on-Wye, Powys, from supposed gastritis, heart disease and inflammation of the kidneys.
But just months later, her husband, Maj Herbert Armstrong, was accused of poisoning a rival solicitor, which led to his wife’s body being exhumed and a murder trial that gripped the nation.
In his new podcast, US journalist Joe Nocera and a host of experts conclude it was a miscarriage of justice.
The case of “the dandelion poisoner”, as Armstrong was referred to by the papers of the day, has all the ingredients of a classic Agatha Christie novel and has been intriguing armchair detectives for more than a century.
