George Oldfield is in charge of the investigation but is short of suspects. However another victim has survived an attack by the Yorkshire Ripper.
Maureen Long was offered a lift home by the Ripper and he later attacked. She survived as she was discovered by two women out for a walk. Maureen gives the police a description of both her attacker and the car he was driving. Even though she is groggy and in a distressed state.
News comes of another Ripper attack, this time in Manchester. Then there is the matter of an attack that took place in Preston a few years earlier but it was ruled out as not linked.
The focus is on taxi drivers, one person is taken in for questioning. Oldfield is sure that Ray Wood is the culprit but the evidence is circumstantial. He needs to obtain a confession whichever way he can.
Like others in charge of the Ripper case. Oldfield finds himself under pressure from the top and Wood manages to have an iron clad alibi when another woman is attacked.
You cannot go wrong with the actors of the calibre of David Morrissey. It is another episode where it is basically a police procedural. Remember the selling point of this series was that it was all about the victims.
Oldfield has to succumb to apply undue pressure on Ray Wood. Any confession by him would had been unreliable.
