Violence against women is out of control. Conviction rates for rape are so low that most survivors think it pointless to report, or later regret doing so. Ruthless trafficking gangs run the sex trade. Women have no confidence in the Metropolitan Police. The year is 1914.

As the First World War began, a group of British campaigners founded the Women Police Volunteers, hoping to protect the vulnerable both from crime and from patriarchal policing and justice. The movement's pioneers included a militant suffragette who'd spent time behind bars, a moral purity activist, a blue-blooded radical, and a court reporter born in the workhouse to a single mother. Sandra Hempel follows their astonishing journey, through all of its troubling turns.

Controlling Women is a vivid snapshot of rapid national change, and a rich tapestry of ethics and emotions among its fascinating characters. Reconciling political ideals with institutional compromise, these bold, complex women made history, despite establishment opposition and destructive infighting. They show us just how far we have to go in the fight for women's justice.
