Steed and Tara investigate the murder of an agent from Cypher HQ. Their progress is stunted by the other Cypher personnel, who insist that they've never seen the dead man. Even so, someone is leaking secrets to the enemy, and the trail of clues leads to an offbeat window-cleaning service. Written by Tony Williamson, "Super Secret Cypher Snatch" made its debut on American television on September 30, 1968; it showed up in England on October 9 of that same year. ~ Hal Erickson, Rovi
