The Fall

The police interview continues. Spector recalls the death of Susan Harper as a sex game gone wrong. Unimpressed, Gibson taunts Spector, telling him to grow up and drop the act, apparently touching a nerve. Spector unexpectedly and violently attacks Gibson, leaving her severely battered. Back at the Foyle Clinic, Dr. Larson informs Spector that he is treatable, but suggests that he is not curable.

Anderson and Ferrington go to London to speak to Alvarez about the murder of the brunette woman in 2002. Later, in an interview with Spector and his lawyer, Anderson and Gibson press for information about Alvarez and the young brunette woman. Spector remarks that it is a smart move by police as he is able to remember this time period.

Sally Ann's car, nearly submerged in the high tide, is seen by a passerby just before it floats away. Spector is transferred to a secure psychiatric facility to undergo evaluation to determine whether he is mentally fit for trial. Spector's legal team try to discredit the confession Spector made to Gibson. Gibson tells Dr. Larson about Spector's sexual perversions.

Spector speaks with a psychiatrist and his lawyers, maintaining he has no memory of any of his alleged crimes. Evidence from the lock-up shows the murder of a young brunette woman in London, a decade ago, for which David Alvarez (Martin McCann), a friend of Spector's, is serving a sentence. The DPP wants to pursue charges against Sally Ann for aiding Spector.

Gibson and Burns are under investigation for the way Spector's case was handled. Gibson and the officers investigate a lock-up used by Spector and discover disturbing photos and journals that suggest further killings. Spector regains consciousness and after interacting with his wife and daughter, it is apparent he is suffering from amnesia.

Silence and Suffering After the events in the forest, doctors battle to save Spector's life.
