Years of investigation have led to this moment … a major breakthrough in the case, a potential answer to thirty years of mystery and pain for the Haines family.

An alleged confession has revealed who might have placed Mark's body on the train tracks on that summer night in 1988.

Now it's time to put the question to him — did he have anything to do with Mark's death? Will Allan Clarke finally have some answers for Uncle Duck?

Blood on the Tracks is the first ever series we made for Unravel, back in 2018.

But we're re-releasing it now with a new episode because the NSW Deputy State Coroner is currently holding a fresh inquest into this case.

Keep listening to the end of this series to find out about the new information that's recently been revealed in the inquest hearings.

This season of Unravel is intended to be listened to as a whole. If you haven't heard all the episodes, you shouldn't draw any conclusions, because you haven't heard all the sides of this story.
