Ponderosa ranchhaned Griff King agrees to pose as the husband of one Theodora Duffy (Karen Carlson). There is nothing personal in this arrangement: Theodora wants to solve a crime, and pretending to be Mrs. King is merely a means to an end. Also in the cast are Ramon Bieri as Jonas Holt, Robert Yuro as Dody Henderickson, Richard Eastham as Stanton and Rayford Barnes as Shaw. Written by Ward Hawkins, "The Marriage of Theodora Duffy" was the last-ever Bonanza episode to be filmed-but was shown next to last, on January 9, 1973. ~ Hal Erickson, Rovi
