Slowly, Stephen Whalby's world begins to collapse around him. His mother's visit has profoundly shaken him and his idealized image of her as forever young and forever beautiful has been shattered. He finally identifies the mysterious man walking the moor as his childhood friend Peter Knowles who has returned to the area after having trekked around the world. Lynn admits to him that she has had an affair but has told Nick it is over and wants to repair her relationship with Stephen. Finally, Stephen locates a cave where he once played and now clearly has someone living there. He also finds evidence that it's the murderer's lair. When a third woman is found dead on the moor, DI Manciple begins to question if it was committed by the same person who committed the first two killings. Written by
