This Is Personal: The Hunt for the Yorkshire Ripper

• Episode 1 - 26 January 2000. Viewers: 7.73m^[3]

Following the murder of 16-year-old Jayne MacDonald in Chapeltown, ACC George Oldfield (Alun Armstrong) is brought in to head up the enquiry into the 'Yorkshire Ripper' by Chief Constable Ronald Gregory (James Laurenson). He soon comes head to head with the current head of the enquiry, Jim Hobson (John Duttine), who has thrown all of his manpower into trying to identify the killer through tyre tracks left at the scene of Irene Richardson's murder. As George re-diverts Hobson's men away from the tyre investigation, Jean Jordan, another known prostitute, is found murdered. Oldfield suspects he may have a direct link to the killer through a £5 note found in the victim's purse, which was newly printed and could be traced back to the bank where it was first issued. As the investigation closes in on eight firms that could have possibly issued the note in an employees' paypacket, another prostitute, Helen Rykta, is found dead in a block of toilets (incorrect: Helen Rytka was murdered and discovered in a timber yard) in Huddersfield, having disappeared after having sex with a punter.

A young girl who was attacked by an unknown assailant in 1975 comes forward and claims that a Photo-Fit printed in a local newspaper is similar to that of her attacker. Although initially dismissed by her local police, the girl's mother refuses to let the matter drop, and demands to speak to the original investigating officer, Hobson. Meanwhile, the police receive two letters claiming to be from the 'Ripper'. Although initially dismissed by Oldfield and his team, the murder of 42-year-old Vera Millward throws the validity of the letters into question as it appears that details of Vera's murder were suggested before the murder took place. Later, Oldfield receives a package in the post containing a tape purporting to be an audio recording of the killer. He initially decides to shield the tape from the press, in order to pursue discreet enquiries in the hope of identifying the killer through vocal recognition. But when news of the tape is mysteriously leaked to the press, Oldfield is outraged and accuses Hobson.

Convinced that the tape isn't a hoax, Oldfield approaches Tracey Brown in the hope that she can identify the voice as being that of her attacker. However, Tracey is unable to confirm Oldfield's suspicions and claims that her attacker spoke with a Yorkshire accent. Continued house-to-house enquiries bring officers into contact with Peter Sutcliffe, and despite his colleagues' misgivings, a young detective constable highlights his concerns to Holland about Sutcliffe, although his pleas fall on deaf ears. The enquiry into the £5 note is reopened when the bank offer new evidence that suggests the note could only have been supplied to one of three firms. Sutcliffe is interviewed again, but once again, no suspicions are raised. Meanwhile, Holland is sidelined from the investigation when his wife, Sylvia (Sue Cleaver), goes into premature labour and their baby dies shortly after birth. Oldfield's health is also deteriorating, leading to a heart attack shortly before the discovery of another victim.

16-year-old Theresa Sykes is attacked on her way from a local newsagent in Huddersfield, and local division identify the incident as a possible 'Ripper' attack. Holland speaks to the victim in hospital and manages to collect another photo-fit. Twelve days later, 20-year-old Jacqueline Hill is found dead by binmen in an alleyway in Leeds. With little progress made since the Ripper's twelfth victim, Gregory informs Oldfield that he is to be taken off the case on the grounds of ill health, and that the enquiry will now be headed up by Hobson. As new year passes, Oldfield begins to settle in to a new job in uniform, although in reality, Oldfield was not re-assigned until after the eventual arrest of Sutcliffe. On 2 January 1981, patrol officers in Sheffield catch sight of a known prostitute in a car blocking a secluded alleyway, and decide to arrest her for soliciting. A standard check on the car reveals that PNC details do not match the vehicle in question, and the officers discover it to be on false plates. The owner, Peter Sutcliffe, is arrested and brought in for questioning. Whilst in custody, officers decide to return to the scene and uncover a knife and a ball-pein hammer. Later, they also discover a second knife found in the police station toilets, both seemingly deposited by the suspect after declaring that he needed the toilet. After intense questioning, Sutcliffe confesses to the murders.
