TONIGHT ON MURDER SHE, WROTE, we enter a chapter of Dr. Seth Hazlitt's past... one he is barely in or has much to do with, it turns out.  Indeed, this is a weird one. UNFINISHED BUSINESS largely focuses on the backstory of one police detective, Barney Kale (Pat Hingle), who seems obsessed with righting a wrong from years back. 

Seth (William Windom) joins our other cast of suspects from a possible murder a decade plus earlier: Dr. Terence Mayhew (Lloyd Bochner), his former secretary and lover Cynthia Tate (Hayley Mills), and gruff fishing resort innkeeper James Sanford (Don DeFore), who welcomes them all as guests again. 

Kale says one of them is responsible for that death that was deemed accidental; and now a fresh faced couple (Erich Anderson and Erin Moran) are pulled into the mix when the reunion is interrupted by another death and Jessica Fletcher (Angela Lansbury) has to match wits with another sheriff (J.D. Cannon) other than Amos Tupper (Tom Bosley) who's not quite as easy to push over.  

It all comes together as a somewhat bizarre edit of a closed-circle mystery, full (and we mean stuffed) of characters about whom we learn bit by bit by bit, and a series of odd motivations that Viktor and Petra try to deconstruct and explain.  

Wish us luck.
