Edith Garrud was a tiny woman. Measuring 4ft 11in (150cm) in height she appeared no match for the officers of the Metropolitan Police - required to be at least 5ft 10in (178cm) tall at the time. But she had a secret weapon.
In the run-up to World War One, Garrud became a jiu-jitsu instructor to the Women’s Social and Political Union (WSPU), better known as the suffragettes, taking part in an increasingly violent campaign for votes for women.
Sick of the lack of progress, they resorted to civil disobedience, marches and illegal activities including assault and arson.
