Duet was a romantic comedy focused on mystery writer Ben Coleman and caterer Laura Kelly as they dealt with all the ups and downs of a relationship, from courtship to marriage.  With them every step of the way (whether they liked it or not) were Laura's quirky sister Jane, Ben's self-centered, neurotic best friend Richard and his demanding wife Linda (whom Ben once dated), and Ben's loyal dog, Reuben. In 1989, this series was revamped and retitled Open House.  Both shows were repeated on Lifetime in the early 1990s.
