Katherine 'Kitty' Marshall was destined to break with convention. Brought up in a socially active family her inherent rebellious streak came into play in 1901 when she daringly divorced her husband and joined the newly founded Women's Social and Political Union (WSPU) campaigning for women's suffrage. In 1904 she married solicitor Arthur Willoughby Marshall and the couple soon became a powerhouse team in the movement: Arthur defending the suffragettes in court while Kitty trained in jujitsu and a member of the WSPU's elite team 'the Bodyguard' helped her close friend Mrs Pankhurst evade the clutches of the authorities under the infamous Cat and Mouse Act. Following events as they unfolded on both sides Mrs Pankhurst's Bodyguard is a gripping account of Kitty and Arthur's incredible work and their fight for political equality.
