Join Lucy Worsley and her all-female team as she delves into the Hampstead Tragedy, one of the most notorious murder cases of the Victorian era.

When the horrifically mutilated body of a young mother called Phoebe Hogg is found dumped by the side of a street in north London in October 1890, the press erupts into a frenzy of speculation that Jack the Ripper has struck again.

But it soon becomes clear to the police that the suspected killer is not a man, but a young woman called Mary Pearcey, a friend of Phoebe’s. This is when forensic science is in its infancy, but it is already featuring in the first Sherlock Holmes stories, and the public is gripped by this case.
