In a longer than usual episode, I’m on the track of Matthew James Jackson and with the help of some great detective work from a listener, we are able to inch closer to the truth. And having spoken to one of Zoe’s old school friends, another long conversation with Zoe really intrigues me.

I uncover the reason why the police believed the dentistry to be unusual, and what that tells us about the police investigation and the victim. Developing other lines of enquiry leads me back to Zoe in Australia, who shares even more intriguing memories.

I manage to find the Scenes of Crimes Officer from the time of the discovery of the body, the man who dug the body out of the ground and the first person to see the body since the murderer, and I learn some fascinating new facts. Then, things take an unexpected and intriguing turn.

A new discovery takes me on an unexpected detour, and takes me on the trail of another missing man

I needed to find the exact date of a story that appeared in the Burton Mail, as it could provide vital information. But how was I going to find three consecutive years of newspapers from 50 years ago - and what would they reveal?

I'm on the hunt for a man who vanished from Burton in 1971. But how do you find someone from 50 years ago who no one has been able to track down since?

A very good question leads to the next stage of the investigation, leading to a series of conversations which open up more and more lines of enquiry.

My most promising lead has disappeared at a critical point of the investigation and that means that my quest to find the identity of the body is at risk.

I'm on the trail of Jozsef Czenner, the man who seems to be associated with a series of strange coincidences. How exactly does he fit into the investigation?

Following the leads from the last episode, I get to work on trying to identify Joszi, the man someone had been looking for in early 1969. But then a discovery deep in the archives raises some further questions about what could have possibly happened to Joszi, and just maybe, an identity.
