Ben Cartwright protects longtime family friend Mary Farnum (Diane Baker) from the drunken rampages of her brutal husband Russ Wharton (Paul Richards). Misinterpreting Ben's kindness, the long-suffering Mary falls desperately in love with the Cartwright patriarch. Also in the cast are Dennis Cross as Monk and Raymond Guth as Goliath. Written by Joel Murcott, "A Woman in the House" originally aired on February 19, 1967. ~ Hal Erickson, Rovi
