Taking advantage of the illness of his powerful rancher father Claude Roman (
Denver Pyle), mean-spirited Jermey Roman (
Jeremy Slate) runs roughshod over everyone. In addition to browbeating his sister Mary (Diane Muldaur) and reneging on a legitimate business deal with the Cartwrights, Jeremy also tries to get his father declared mentally incompetent. But by episode's end, Jeremy forcibly learns that there's more to greatness than merely inheriting a great name. First telecast on October 13, 1968, "The Passing of a King" was written by B.W. Sandefur. ~ Hal Erickson, All Movie Guide
