Lucy Worsley travels back in time to revisit the unthinkable crimes of 19th century murderesses from the UK, Australia and North America.

Lucy Worsley travels to Buckland Brewer, Devon, to investigate the death of a young servant girl on a remote farm. Far from bucolic idyll with roses around the door, this is the location of a grizzly crime where a teenage girl, Mary-Ann Parsons, is found dead, her emaciated body horribly bruised and battered.

Guest Detective Baroness Helena Kennedy, a leading barrister and expert on human rights and modern slavery, joins Lucy to examine the crime. The alleged Lady Killer is Sarah Bird, a young farmer’s wife and the mother of four children. Could she really be capable of this brutal murder?

Together with Lady Killers’ in-house historian Professor Rosalind Crone, the team examines how Mary-Ann Parsons comes to work as a Parish Apprentice at Gawland Farm, and how a toxic culture of abuse becomes the norm. With a wealth of experience in modern slavery, Baroness Helena Kennedy unpicks how people become trapped in domestic servitude today and what it takes to turn someone into an enslaver.
