Assigned to investigate the disappearance of five fellow agents, Steed ends up being accused of their murders. Alas, the only person able to prove his innocence has completely lost his memory. Acting on her own volition, Cathy tries to get to the truth herself and learns a few unpleasant facts about her "trusted" colleagues. Written by Martin Woodhouse, "The Wringer" was originally telecast in England on January 18, 1964; it made its American TV bow on March 26, 1991. ~ Hal Erickson, Rovi
