"Killer Whale" was the last episode from the second season, another lackluster ringside plot, ala "The Decapod." The enigmatic Patrick Magee, a mainstay of low budget British horror films, makes a fine villain (soon to play another in "The Gilded Cage"), as Sam "Pancho" Driver, manager of a gymnasium where boxers train, and a little illicit smuggling occurs. Steed finally gets equal footage with Cathy, allowing her to manage a prospective young boxer at Pancho's gym, Joey Frazer (Kenneth Farrington), but when he washes up with a bar of soap discovered in another man's locker, it turns out to be a sample of ambergris smuggled in from the Caribbean, used in making perfumes. John Bailey ("A Change of Bait," "Dial a Deadly Number," and "Killer") plays Fernand, Pancho's partner in crime and owner of the couturier where Steed pretends to be a buyer of a complete new wardrobe for a fictitious niece, and while giving Fernand her 'measurements,' lasciviously eyes the smiling receptionist (Lyndall Goodman), who realizes that Steed's niece has the same figures! We are also intoduced to Cathy's new push button apartment, a main feature in season three. Among the series veterans are Morris Perry ("Tunnel of Fear" and "Dragonsfield"), John Tate ("Build a Better Mousetrap"), Robert Mill ("Double Danger"), and Fredric Abbot ("The Gilded Cage"). Credited as 'Models from the Kenneth Sweet Collection' are June Hodgson, Diane Keys, and Elaine Little.
