Haunted by memories of a failed arrest, Detective Inspector Huw Miller retires. Huw remains busy searching online about the Ripton Stalker. When a seemingly friendly new neighbour moves in, Huw is convinced his past has just moved in next door.

Huw's promise to Alice to forget about Patrick and the Ripton Stalker comes under strain. Huw visits Patrick's repair shop. He sees a collection of polaroids. Patrick responds coldly when Huw asks to take a photo. Huw sneaks into Patrick's house.

Patrick charms his way into chatting with Alice and Margot while Huw's desperation sets in. He questions Declan about his connection to the Ripton Stalker, but Declan kicks him out. Huw pleads with Alice, who offers an ultimatum.

While the street has seemingly turned on Huw, Alice and Margot stand by him. Returning from Ruth's funeral, Huw finds a polaroid on the table. Patrick was here. Sending Alice and Margot away, Huw vows to confront Patrick on his own.
