Chasing Shadows - Season 1 Episode 2

Stone and Inspector Prior discover Ruth, who has been knocked out by 'Leanne' who is a man and Stone deduces that he lures teenagers to their deaths and make them appear to be suicides. Stone notes that sites where corpses were found and Ruth attacked are owned by a property company and visits their housing project, finding runaway Chloe Amos. She says that she was squatting in the building but was attacked by a man she disturbed and who escaped in a car, which Stone partially identifies. He is carpeted for his rude, unorthodox manner but traces the car to the company's security firm and John Meadows, who he is convinced is the murderer. Meadows is arrested but 'Leanne' posts another message, making Stone and Ruth realize that Meadows has an accomplice, who must be found in order to save Taylor.
