In order to transfer vital information to the Allies in London, Hogan must convince Klink to take a circuitous trip to "Argentina." This requires the service of underground agent Erika Weidler, who seductively plays up to Klink. At a crucial juncture, Erika's outraged husband (actually Sgt. Carter in disguise) charges in and challenges Klink to a duel -- so naturally, the Commandant is more than willing to allow Hogan to help him escape to the Western hemisphere (or so he thinks). In her second Hogan's Heroes appearance during the series' third season, Antoinette Bower is cast as Erika. Written by Richard M. Powell, "Duel of Honor" first aired on February 3, 1968. ~ Hal Erickson, Rovi
