The murder of Diane Sindall in Birkenhead, Merseyside led to Britain’s longest miscarriage of justice when local man Peter Sullivan's conviction collapsed after 38 years. This series returns to the streets, alleyways and estates of Birkenhead where it all happened, retracing Diane’s final movements. Follow through eyewitness testimony, unheard accounts and modern forensic science as we uncover how a brutal crime in a public place went unsolved for decades, while a killer may still be alive and closer to home than anyone realised. At the heart of this story is Diane: who she was, how violence against women shaped the investigation and what justice really looks like when a community has lived with fear, silence and unanswered questions for generations.
