Lucy Worsley investigates the crimes of Victorian women from a contemporary, feminist perspective.

In this episode, Lucy explores the case of a young lady called Madeleine Smith. Part of high society in Glasgow in the 1850s, she was living the ideal life, attending balls and concerts, promenading around the shopping districts and spending her summers at her family’s large country home.

But she was hiding a shameful secret - a clandestine love affair with a man ten years her senior and well below her station. His name was Pierre Emile L’Angelier, a warehouse clerk from Jersey. They met, wrote letters to each other regularly, and soon their relationship turned intimate. But when he found out she was soon to be married to a suitable match arranged by her parents, things turned sour.

While Madeleine was burning the letters she received from Pierre Emile, he kept hers and threatened to send them to her father to expose their relationship. In a panic, Madeleine begged to meet so he could return her letters.

On the evening of 22nd March 1857, Pierre Emile left his lodgings, allegedly to visit Madeleine. When he returned home, he became ill and died of arsenic poisoning. Police traced Madeleine through an entry in his diary, and she was arrested. She was put on trial for his murder and her letters, intended only for the eyes of her lover, were read out for all to hear.

Presenter Lucy Worsley is joined by award-winning crime writer Denise Mina to piece together this curious case. Was Madeleine a manipulative young woman who wanted a bit of fanciful fun before marriage? Or was she naïve and innocent, swept off her feet by a controlling older man? And was she guilty? Or was the outcome of her trial determined by her class, gender and societal expectations of women?

Together with historian Rosalind Crone from the Open University, they visit the alleged scene of the crime to investigate if Madeleine could have possibly poisoned Pierre Emile L’Angelier that fateful evening in 1857. Lucy and Rosalind also visit some of Madeleine’s real letters at the Mitchell Library in Glasgow learning that, perhaps, a younger upper middle class Victorian lady may not have been as prim and proper as history would have us believe.
