Episode list

Babysitter Sasha Lowood is murdered by a man dressed as the mythical bogeyman at the same time that Calvin Mantus, who killed his family in a manner similar to Sasha's slaying, escapes from a secure unit. The police search Mantus' old house, which feels haunted, and where there is a poster of actor Lon Chaney in the film 'London After Midnight'. According to unit head Dr. Mortlake, this was Mantus' favourite film and was said to drive its audiences mad. After psychiatrist Morgan Lamb survives an attack by the bogeyman, a masked man is seen toting a gun. But is he what he seems?

Buchan theorizes that the killers are cannibals, eating their victims to assume their power and goodness. Following Josie's disappearance, Miles and Chandler learn that she too was interviewed by Dunn, and that he is part of an exclusive dining club - though they feed on endangered species, not people. After Josie's body is found Miles installs a CCTV camera in the police station, which captures Louise Iver committing acts of sabotage which have caused the recent disasters. He believes she is an immortal succubus, inciting others to murder, though Buchan is sceptical. After a vicar, a member of the dining club and another person hailed for good deeds, is killed his widow points the police to the Abrahamians, a doomsday cult expecting the end of the world and sacrificing the godly to save their souls. They are successfully pursued but Iver remains at large to have the last word.

The killer has struck again. With one of their own as the latest victim, the police have to prepare for what should be the final murder. From the CCTV footage, they are able to trace the driver of a van that was in the area and in which they find blood evidence. It is soon evident however that the murderer has in fact stolen someone's identity and the police come to yet another dead end. DI Chandler develops his own theory as to the identity of the original Ripper leading him to a block of flats where he is assaulted. Information in the killer's flat gives them the identity of the next victim, and they race desperately to locate her before the newborn Ripper strikes for the last time.

Another boy is killed, and all three victims are discovered to have been in the same school form as Mantus' sister. Morgan survives another attack, injuring her assailant, but she has no connection with the other victims, and young DC Kent feels she is holding something back. Miles believes Mantus is not the murderer and the fact that the three victims all fell foul of recently deceased caretaker Dave Watney seems to prove his point. Does the late Dave have an avenger? Is Morgan the accomplice? Or is Mantus, seen to be nursing a leg injury, the killer after all?

Despite having given a heads up to Commander Anderson about his theory, DI Chandler is called before a review board after a second murder takes place. Again, it has all the earmarks of Jack the Ripper's second murder 100 years ago and appears to vindicate his theory of the copycat killing. DS Miles checks with some of the girls who are on the game and there is a soldier, eventually identified as Pvt. John Leary, who's been roughing some of them up. They bring him in for questioning but he proves less than cooperative. As some of his squad begin to develop at least a modicum of respect for him, Chandler stuns them by coming up with another key piece of evidence: the killer's DNA which the pathologist got from the victims' eyeballs, the killer having apparently licked them at the time of the murder. With Leary refusing to cooperate, the forensic report on the DNA reveals it to be contaminated and the police are no further ahead. Chandler finds himself under pressure when the media gets hold of his copycat theory and it's apparent that one member of his squad has let the cat out of the bag. On the night of the next expected killing, the police make an arrest and Chandler puts DS Miles in charge of the interview. CCTV footage leads Chandler in a different direction.

After another family is killed, the custody officer admits that Salter terrified him into releasing him. Salter was owed money by the victims, as he was by his brother, and he is eventually cornered in a cinema and recaptured. However he is exonerated following the slaughter of another household, the link to each slaying being that in each case a selfish young woman is spared. Buchan's research leads to a man who was familiar with the murder sites and had a grievance against an arrogant female driver. Have the police got their man this time?

Following the discovery of a third corpse, flayed like the others, Sabina Masud talks to Chandler. She explains that Baldaev was the leader of a Russian extortion gang demanding money from her father. When he refused to pay Baldaev stalked her and she was in the graveyard when he was killed, describing his slayer as resembling an old woman wearing a leather mask. This fits the description of the person who abducted young student William Tierney Clark. Clark, like the other three victims, was acquitted in a case where somebody was killed, suggesting a revenge motive by the murderer. Clark survives and, in hospital, questioned by Chandler as to the identity of his attacker, writes the letter W. A suspect is brought in but Buchan pursues his own enquiry, confronting the killer and having to be rescued by the other team members.

In the sewers beneath as Whitechapel church two workmen find the disembowelled corpse of young runner Thomas Griffin. Dr Llewellyn believes his killer removed his stomach and entrails. A camera rigged up in the sewer leads to zoologist Mark Hooper but he was only testing an urban myth to see if feral pigs roamed the sewers. The next victim, Anne Ayres, is found in the same state as Thomas and, like him, was feted for local charity work. Both were profiled by journalist Peter Dunn, who, when visited by the police, is cooking something that smells very strange. At the same time urban farmer Josie Eagle is also pursued by a sinister group. Miles is concerned as to how Wingfield seemed to have known so much about the police's cases whilst Megan stops Mansell from killing himself.

In the wee hours of the morning, a Police Community Support Officer discovers the body of a woman lying in a yard. The victim is Cathy Lane and the medical examiner determines she was strangled and that her throat was slit. The attack probably lasted no more than a few minutes but the killer tried to gut her as well. The police, led by newly appointed DI Joe Chandler, at first focus on her husband Rob Lees, a brute of a man who also happens to be a butcher, but he has the perfect alibi: he was in the drunk tank at Charing Cross station at the time of the murder. Ripperologist Edward Buchan suggests to them that this murder is identical to Jack the Ripper's first murder, and that another attack on Emma Jones also matches one from over 100 years ago. DI Chandler soon recognizes a pattern to the killings, much as Buchan suggested. His major problem however is that his squad, led by DS 'Skip' Miles, have absolutely no respect for him and see him as just another fast-track university graduate who knows nothing about policing on the street.

After a fox drops a woman's severed hand in Whitechapel DI Mina Norroy arrives from Richmond, where the rest of the torso has floated down river. The woman was poisoned and then dismembered. Ella Bowe, missing from home for six months, seems a likely victim but is proved not to be. The police locate the fox, following it to the garden of the heavily booby-trapped house of weird reclusive Adelina Grace. A woman's foot is in the garden and Adelina's dead husband's body is inside the house, but he was not murdered, and none of the potions Adelina makes can be identified as the fatal poison. Then another woman's foot is found.
