Avengers Cast

Top-secret information is apparently being leaked through a funhouse located in Southend. Meanwhile, Doctor Keel coincidentally treats Harry Black, a man recently escaped from prison who was injured while working in the funhouse. Steed takes a job at the funhouse, but he is exposed by the funhouse hypnotist, who knocks him out, and then attempts to extract information from him. When this ploy fails, Steed is imprisoned on the ‘Ghost Train’, where he discovers a machine that transmits coded information to Europe is being used by Wickham, the boss of the funfair. Doctor Keel arrives at the funhouse just in time to find Steed bluffing his way out of captivity with the use of an ‘exploding cigarette’.
