Episode 6

As the motives stack up against suspects Gregg and Harry, Kit's killer sends another violent warning and Judith, Becks and Suzie find themselves in a race against time to solve the case.

After a near miss almost results in another death, the police heighten their investigation. With Gregg still missing and the motives stacking up against Harry, the two men become the focal point of the scrutiny. And when Suzie successfully locates Gregg, the police are able to take the inebriated man into custody – but did his bitterness towards Kit really push him to murder?

Meanwhile, when it's revealed Harry had more motive to kill Kit than initially anticipated, Jackie has to face the truth that her father could well be a killer.

Believing there to be a connection between the murder and the ongoing thefts, Judith employs the help of volunteers from the archaeological dig as well as Becks and Suzie to enact a plan to catch the thieves red-handed. While the plan works, tragic news cuts through their success and it becomes clear that Kit's killer is going to stop at nothing to keep their identity concealed.

Growing ever more determined to solve the mystery, Suzie inadvertently reveals too much about the case and puts herself in danger – will they be able to catch the killer and save Suzie before it's too late?
