Lucy Worsley is back with a new series of Lady Killers, where true crime meets history - with a twist. In this episode, Lucy travels back to 1831 to Aldgate, then a poor part of East London, to investigate Elizabeth Cook, an Irish woman with a dark criminal background. When Elizabeth’s new lodger, an elderly peddler called Caroline Walsh, goes missing with no sign of her body, suspicions are high. When Elizabeth is discovered selling Caroline’s clothes, she is accused of her murder by her own son in court. With Lucy to find out more about the case of Elizabeth Cook is Jaswant Narwal, the Chief Crown Prosecutor for London North, and the person who would prosecute this case if it came to court today. Jaswant shares her 35 years of experience prosecuting homicides, including ‘no body’ cases. Lucy is also joined by historian Professor Rosalind Crone and they visit Aldgate to find out more about Elizabeth Cook and Caroline Walsh. They also go to the site of the Royal London Hospital to discuss the grisly fate of many of London’s missing persons in the early 19th century. Lucy wants to know what this case tells us about the lives of poor women in London in the 1830s. Can someone today be accused of murder if there is no body? Would Elizabeth Cook’s case go to court today and, if it did, what might the outcome be?
