The Avengers' second season came to a close with this episode, which originally aired on March 23, 1963. Written by John Lucarotti, the plot concerns an effort to smuggle valuable ambergris. Steed and Cathy become part of the action in a circuitous manner, when Cathy agrees to manage an up-and-coming prizefighter (Kenneth Farrington). Certainly one of the more labyrinthine Avengers episodes, "Killer Whale" wasn't given an opportunity to baffle American cable TV fans until March 2, 1991.
