TMDB rating 7.0/10 Ended
The XYY Man is a 1976–77 British crime thriller television series created by Kenneth Royce, based on his novel series about reformed cat burglar William 'Spider' Scott, recruited by British intelligence for secret missions due to his unique genetic makeup (an extra Y chromosome), which supposedly predisposes him to crime. The plot follows his reluctant work for the secret service and his constant pursuit by the dogged Detective Sergeant George Bulman, leading to spin-offs like Strangers and Bulman.
