The Loch

Following the discovery of a human heart on the shores of the loch, forensic psychologist Blake Albrighton is brought onto the team.

As Annie becomes more entrenched in the investigation, Alan feels increasingly marginalised and their relationship begins to suffer.

Despite being threatened with arrest by Quigley, Albrighton continues to obsess over evidence. About to leave, he hears something that makes things click into place. Unable to face Quigley, Albrighton risks his life to prove hes right.
