This time around, Steed and Peel come up against an "invisible man." Actually, he only feigns invisibility, but his deception is enough to nearly bankrupt the British government, as the villain merrily steals important documents on behalf of a pair of sinister foreign agents. Roy Kinnear, best known for his work in director Richard Lester's films, guest stars as Quilby. Written by Philip Levene, "The See-Through Man" was first telecast in England on February 4, 1967 -- one day after its American TV debut.
