A party is being held for the launch of Buchan’s first book called ‘A History of Murder in Whitechapel’. The team attend to offer him some moral support. A little old lady at the party makes pointed comments to the team which sour the evening a little, especially after she reminds Chandler that he has yet to make a conviction. Chandler and Miles investigate a bizarre murder after a vagrant is slowly crushed to death by some stones.

A connection to a 16th century murder seems to confirm that someone is killing witches in Whitechapel, but the investigation is impeded when a link to present-day espionage attracts the attention of the security services. Chandler is on the case, only for it to appear that there may be a malign influence at the very heart of the team. The station pulsates with unexplained phenomena, and even Miles starts to ask questions. Is anywhere truly safe, and who or what is behind the evil that seems to be surfacing all around?

Following the discovery of a flayed face in a local gallery, Chandler and Miles find themselves becoming involved in the contemporary art world.

As more flayed bodies turn up, Chandler and Miles question the motives behind these bloody deeds. Buchan's research puts him in danger.

A disembowelled body is discovered in a sewer. The team must establish whether a killer is at large, or if feral swine have returned to London's sewers. Chandler has to pull the detectives together after an abysmal team-building exercise.

The hunt is on to find a gang of suspected cannibalistic killers lurking in the sewers before a missing girl becomes the next victim. The station is under attack and the forces of evil are moving against the team on all sides, and as the case takes a dangerously personal twist for Chandler, he must resort to desperate measures.
