During the journey to Jamie Greyson's house, Gladys Cramer's erratic driving behaviour raises suspicions, prompting Detective Karl Jenkins to pull her over once again.
As Detective Karl Jenkins and his partner, Sarah, follow Gladys Cramer up the winding Berriedale Road, they observe her engaging in distracted driving, seemingly texting on her phone. Despite the danger posed by her actions, Gladys initially fails to respond to their signals to pull over, nearly grazing the metal barrier along the road.
When Gladys finally stops, Karl approaches her vehicle, confronting her about the texting while driving. Gladys adamantly denies the accusation, offering her phone for Karl to check. Upon examining the device, Karl uncovers a surprising connection: Gladys is the sister of Beatrix Cramer, a figure from a past case that left a lasting impression on him.
Further investigation of Gladys's phone reveals a concern-filled message she had sent to Jamie the previous day, as well as a recent, brief call to Luke Smith, Jamie's partner. These discoveries fuel Karl's suspicions about Luke's involvement in the case, strengthening his belief that Luke is "up to no good."
Maintaining a professional facade, Karl agrees to continue their journey to Jamie and Luke's house, driven by a growing sense of urgency to uncover the truth behind the disappearances.
