Steed infiltrates a school for butlers in order to unmask a traitor. While he is being drilled in the finer points of silent servitude, Emma attempts to charm her way into the heart of a suspected turncoat who is also a notorious lecher. If any doubts still lingered that The Avengers was not intended to be taken seriously, this episode would dispell them instantly. Written by Brian Clemens, "What the Butler Saw" first aired in England on February 26, 1966; it was subsequently shown on American network television on July 28, 1966. ~ Hal Erickson, Rovi
