Emilia Fox and Britain’s top criminologist, Professor David Wilson, cast new light on the Jack the Ripper case. Together, they examine the Ripper’s modus operandi using modern technology to recreate the murder sites to help understand the extraordinary risks the Ripper took to kill his victims. Using the Home Office Large Major Enquiry System (HOLMES)—a bespoke computer system used by the police to help detect patterns in criminal activity—and evidence uncovered within the investigation, results strongly indicate another woman was, in fact, the first Ripper victim.
