Steed and Emma attend an auto rally where they participate in a car treasure hunt. But it isn't all fun and games: our hero and heroine are searching for a valuable object, hidden in one of the cars by a murdreed agent. This is the one with the deadly "thrill-ride" sequence, with Emma as the unwilling participant. Written by Michael Winder, "Dead Man's Treasure" originally aired in England on October 21, 1967; its American debut followed on March 13, 1968. ~ Hal Erickson, Rovi
