Regular viewers were in for a jolt when, early in the proceedings of the December 18, 1965, episode "Two's a Crowd," hero John Steed was killed right before their eyes. Actually, the dead man was a double of Steed, an enemy agent hired by a mysterious masterspy known as Psev. As the real Steed tries to get to the bottom of things, Emma becomes convinced that her partner isn't her partner at all, and thus is a candidate for elimination. Written by Philip Levene, "Two's a Crowd" made its British TV debut on December 18, 1965, and its American TV bow on May 9, 1966. ~ Hal Erickson, Rovi
