Lucy Worsley presents a brand new series – Lady on Trial, where courtroom drama meets history with a twist. Lucy and her team of all female detectives explore the lives of women involved in some of history’s most famous – and infamous – legal battles. Women who face the law head-on and don't always play by its rules.

This time, Lucy is joined by the Baroness Hale of Richmond, first female president of the UK Supreme Court, to uncover the extraordinary story of Caroline Norton – a celebrated writer and socialite, accused of adultery with the British Prime Minister in a scandalous ‘Criminal Conversation’ trial in 1836. The courtroom is packed to the rafters, her private life scrutinised in excruciating detail, but Caroline cannot attend, give evidence or fight her corner.

Socially ostracised and denied the right to see her three sons for years on end, Caroline channels her personal experience of injustice into a remarkable campaign to change the law on the custody of children. Her fearless activism also contributes to the dismantling of coverture, the common law doctrine that meant women had no legal existence of their own after marriage. They were completely subsumed or ‘covered’ by their husbands’.

Lucy and Lady Hale look at family law today, thinking about what has changed and what could still be improved, especially for children when a relationship breaks down. Caroline Norton never calls herself a feminist, and they reflect on why that might be and the true meaning of feminism in the present day.

Professor Rosalind Crone from The Open University sets Caroline’s case within the wider context of married life in 19th century Britain and explains how women used their ingenuity to beat the system wherever possible.
