The Long Shadow

When a woman is murdered in Leeds, the police struggle to catch her killer; a desperate mother facing financial hardship makes a difficult decision to keep her family afloat.

The police question Emily's husband after her murder; a woman who survives an attack describes the perpetrator, but her testimony is given little weight.

The investigation spreads to Bradford with the murder of another young woman, and a female police officer is tasked with dangerous undercover work whose risk is ever present for the real sex workers.

When another woman survives an attack, detectives hope they are in with a chance of finding their man, and later, a driver in Leeds emerges as a prime suspect.

The police review previous attacks in an effort to find more victims as the murder rate rises; the delivery of a letter from the murderer enrages George Oldfield.

As several detectives start to express reservations about the course of the investigation and the reliability of their evidence, West Yorkshire Police issue a large public appeal in the hopes of apprehending the murderer.
