Traces

Emma Hedges' return to Dundee brings her mother's unsolved murder into sharp focus. However, a fatal fire in a nightclub proves an ominous omen.

While glad of McKinven's help, Emma still feels overwhelmed by the police interest and wonders what she's started. But when the stars align to put Daniel in her path, Emma feels a deep connection.

McKinven's inquiries ruffle feathers and a furious Julie chides Emma for dragging up the past. When Emma is threatened with a knife, it's clear that someone's hiding something.

Daniel faces a culpable homicide charge for the fire and wants to protect Phil's reputation, but when Emma meets Phil for the first time, her instinct tells her to be wary of him.

Emma's accusation against Phil drives a wedge between her and Daniel. McKinven urges Emma to stop sleuthing, as he's certain that the person who killed her mother is known to her.

Daniel gives McKinven the lead he needs to make an arrest, but it's the exacting forensic science that finally brings peace for Emma.
