Synopsis by Hal Erickson
Long before he was cast as Murray Slaughter in The Mary Tyler Moore Show, Gavin MacLeod popped up in this Dick Van Dyke Show episode as Maxwell Cooley, the cousin of "Alan Brady Show" producer Mel Cooley (Richard Deacon). Maxwell happens to be in the jewelry business, and he manages to sell Rob (Dick Van Dyke) a replica of a necklace once given to Empress Carlotta by Emperor Maximillian. Rob thinks that this would make an ideal gift for his wife Laura (Mary Tyler Moore). But there's a hitch: Laura thinks that the necklace is hideous -- in fact, she is convinced that it was the reason that Empress Carlotta went mad! And there's another hitch: Laura hasn't the heart to tell Rob.
