Tom falters on the tightrope between his police investigation and his illicit pursuit of the murder weapon and the gold, as it all threatens to come tumbling down.

Tom is forced to deal with the killer in order to stay in the hunt for the gold, but a revelation from Izzy threatens to knock him off course.

With the origins of the gold confirmed, an American gangster arrives in Dunfolan to take back what is his. Birdy makes a shocking discovery.

Tom and Olivia work together outside the official police investigation as their search for the gold forges a most unsavoury alliance.

The search for Robert Dardis leads Tom and Niamh to an abandoned house. Tom takes advantage of the unfolding situation to deceive his colleagues and try to find out more, but a heated confrontation leads to a fatal mistake. Tom's relationship with Olivia deepens as each recognises the value the other has in their search for the gold.

The body of an accountant is found on the shores of Strangford Lough. Tom Brannick and Niamh McGovern are assigned to the case.

The accountant is woven in to the tapestry of Tom's tumultuous past, and now Tom must find out who the killer is and where the accountant had been hiding his gold all of these years.
