The Alice Wheeldon Story – When Conscience Became a Casualty of War | Deidre and Chloë Mason
On 20 February 2014 Deidre and Chloë Mason presented the Jessie Street National Women’s Library Lunch Hour Talk.
About Deidre and Chloë Mason
The late Deidre Mason and her sister Chloë shared a family heritage of peace and social justice activism. Their great grandmother Alice Wheeldon, a suffragist and courageous anti-war campaigner, was subjected in 1917 to a questionable conviction for conspiracy to murder Britain’s Prime Minister, David Lloyd George.
Deidre and Chloë were both activists from an early age, joining their parents in anti-war, anti-arms race and anti-conscription action. They were unaware of their family’s rich heritage of standing for social justice until just prior to their father’s death.
Deirdre Mason died in 2017 after a lifetime of activism. Her sister, Chloë Mason, continued the work and in 2019 submitted an application to the Criminal Cases Review Commission seeking referral of the Wheeldon case to the Court of Appeal and the quashing of the convictions.
Chloë continues to write and speak about the injustice suffered by her family and its wider implications, including the human costs of war, undercover policing of political movements and the integrity of the criminal justice system.
Summary of the presentation
Chloë and Deirdre Mason told a poignant story of persecution suffered by their family during the First World War and its enduring impact across generations. Their parents revealed the truth only in 1986, when their father was dying. Until then, the sisters knew little of their grandparents’ imprisonment or the events that had shaped their father’s life.
Their great-grandmother, Alice Wheeldon, was a socialist, suffragist and anti-war activist in Derby. In December 1916, a Ministry of Mu*****ns security agent, posing as a conscientious objector, approached Alice and offered to arrange safe passage to America for members of her family in return for poison allegedly intended for guard dogs at a London internment camp. Alice obtained the poison from her son-in-law Alf Mason, a dispensing chemist, and handed it to the agent. The agent subsequently reported a supposed plot to poison Prime Minister David Lloyd George and others.
A highly publicised trial followed in 1917. Alice, her daughter Winnie and Alf were convicted and imprisoned. The case was used to discredit anti-war activists, while Alice was portrayed as a dangerous criminal. She died in 1919 and was buried in an unmarked grave.
Decades later, research began to challenge the official version of events. Historian Nicholas Hiley uncovered evidence that the undercover operation extended beyond suspected German activity to surveillance of socialists, suffragists and anti-war campaigners. In 2013, Alice’s reputation was further restored when a blue plaque was erected on her former home, describing her as an ‘anti-war activist, socialist, suffragist’.
At the time of presenting the talk Deidre and Chloë Mason were continuing their campaign to clear the family’s name, highlighting the dangers of secrecy, undercover policing and failures of disclosure. Their story demonstrates how wartime repression can create injustices that endure long after the conflict has ended.
Postscript: On 15 June 2022, the BBC reported that the Criminal Cases Review Commission had declined to refer the convictions of the three people found guilty of conspiring to assassinate the prime minister to the Court of Appeal. While acknowledging that the application raised credible grounds for questioning the convictions, the Commission considered the age of the case and the likely cost of further proceedings. It nevertheless noted that the evidence presented could create a ‘real possibility’ that the convictions might ultimately be overturned. Downloads of the application, the CCRC's decision, and response to it are online (https://alicewheeldon.org/criminal-cases-review-commission).
