Chasing Shadows - Season 1 Episode 3

Stone persuades Ruth to join him in investigating the disappearance of solicitor Steve Eli, tracing his last journey to a spot where two other men were slain. From this Stone deduces that taxi driver Leonard Vance, who killed both victims, also murdered Eli and he and Ruth interview Vance in a secure hospital in the company of his psychiatrist Dr Ellesmere and Alex Wernley, who wrote a book on Vance and other killers. Vance admits to killing Eli but claims not to remember where he hid the body and when Stone takes him to a likely burial place he collapses and is rushed to hospital. Stone now believes Vance to be innocent but when he gets to the hospital Ruth tells him that the man is dead.
