The Avengers - Season 5 - Eps 9: The Correct Way to Kill
Foreign agents are being killed, but not by British agents. Steed thinks it terribly unfair, and so does his opposite number, Nutski. They make an arrangement, and Steed and Emma find themselves with Soviet partners in an investigation of a group of very British killers.

Synopsis
A quirky spy show of the adventures of eccentrically suave British Agent John Steed and his predominantly female partners. Jonathan Steed - an urbane, proper gentleman spy - teams with various assistants throughout the series' run, including Dr. David Keel, Cathy Gale, Emma Peel and Tara King, to repeatedly save the world from diabolical schemes plotted by equally diabolical evil-doers (among them robots and man-eating monsters).
