Episode 1

The Moors murderers, Ian Brady and Myra Hindley, were sentenced to life in 1966 for killing three children. In fact, they had killed five children, and 12-year-old Keith Bennett has never been found.

But now a team, including author and film-maker Duncan Staff, former murder detective Martin Slevin and forensic archaeologist Professor John Hunter, has examined past investigations, rediscovered files and delved into Ian Brady's archive. They reveal possible grave sites, uncover critical material and perhaps help to solve a case that's remained open for nearly 60 years.
