H.G. Wells' Invisible Man

Man in Disguise (2x9)

Air date: Jun 07, 1959

Brady is tricked at a Paris airport, and has his bag and passport stolen - a criminal disguised as Brady uses his passport to travel across to England with a suitcase full of cocaine. Annoyed at this, Brady offers to help the police track down the dealers in London. A decent epsiode with Brady pulling some rather clever tricks to track down the dealers and plausibly getting involved in the story (wanting revenge for them impersonating him), although the ending is rather rushed and their plan to catch the villains relies on quite a big assumption.
