Lucy Worsley is back on the detective trail, reinvestigating four dramatic chapters and iconic characters in British history - the Gunpowder Plot, Bloody Mary, Jack the Ripper and the legacy of William the Conqueror's invasion of 1066.

Examining each case in forensic detail, Lucy follows the evidence to uncover overlooked witnesses and victims, new heroes and villains while exploring how the mysteries unlock issues that speak to modern audiences - from the media treatment of female victims, the experience of the poorest in society to the political radicalisation of young people.

Who killed the Princes in the tower in 1483? What actually caused the Black Death? Why did a witch craze sweep 16th-century Britain? Was George III really mad? These are some of the most enduring and perplexing questions that have baffled academics and fascinated history fans for years. In Lucy Worsley Investigates, the historian turns sleuth by reopening and completely re-evaluating these infamous mysteries. She follows the evidence, bringing a contemporary perspective to each mystery. Worsley explores how changing attitudes to gender politics, class inequality, mental health, and children can challenge our perceptions of the past and provide new answers to each mystery.
