We've found ourselves focussing on a series of horrific crimes perpetrated in Belgium. A crime spree that involved a very tall man - A man known as The Giant by the Belgian police. We needed to know more about this man to see if there was any potential link to the Gentleman. There was one person who we could turn to; A journalist who has been covering that case for over 20 years - and it's a fascinating story.

We are on the lookout for Giants, and we've found a 6'5" man who is acquitted of murder, with striking similarities to the Gentleman, but that all depends on what happens to him afterwards? And is he the only giant we need to be taking a much closer look at?

We need to catch up on the victims of the Barbel, we take a new approach to looking for potential people who may be the Gentleman with positive results, and the investigation takes a European turn.

We're back on the case - We learn more about isotopes and Iain makes a very intriguing discovery.

We have two men in our sights as our search for the Gentleman of Heligoland continues. David Martin, the Australian millionaire who went missing in 1992 and David Krueger, the 6'5" German man missing from Canada - But how can we rule them in or out?

Things are moving quickly in the investigation. New clues, new science and we're on the trail of two new potential victims

In the first of our mid-season updates - German police release a very significant scientific finding that changes their thinking on exactly from where the Gentleman may have originated. But there might be a fly in the ointment

In the final episode of Season One, we discover that the skull may be able to tell us far more about the victim's physical appearance that we first thought. Something which may eventually be vital in identification. And, as the first season draws to a close, we pull together some loose ends and our thoughts on the case so far.

With great help from our Facebook group members we are able to finally identify the man who fell from the Pride of Flanders, a few months before the Gentleman of Heligoland was found.

Armed with his name, we are able to start piecing together what happened, how exactly he fits into the story and where that can take us next.

Thanks to a listener, we discover another report on the case, which reveals critical new information. Information that allows us to analyse the injuries in more detail. What does this tell us about how the Gentleman of Heligoland met his death?

There’s a lot going on. We find another piece of information about the man who went missing from the Pride of Flanders, explore how the currents in the English Channel and North Sea may takes objects far from where they entered the water, and then the police issue a new press release that reveals some interesting insights into how their thoughts are developing and provides some new information we can immediately get to work with.
