The Dead Land (2) (S06E08)

A new serial killer is on the loose, targeting homeless men by stabbing them directly in the heart. However, there's an unsettling ritual involved, as the victims are washed and meticulously wrapped in paper before being discarded in the downtown area. When Alex is called away, her position is filled by the young Oxbridge graduate, Hall, who initially raises Tony's suspicions. Yet, Hall proves to be knowledgeable with a degree in psychology and a genuine admiration for Tony’s work. Meanwhile, a more ominous admirer, clearly Bryant, is leaving unsettling 'gifts' on Tony's doorstep.
