It's always pleasant to see which favorite actresses/actors from the past enliven this series with their guest appearances. Here, Don DeFore, much underrated generally, maybe because he's played so many likeable guys, turns in his usual good job.
This episode has the ingredients of a very good program, and it starts out well - a retired police detective, Barney Kale, sets out to show that his former coworker, Detective Dixon, did not have a natural drowning accidental death ten years ago, but was murdered.
There's the Maine setting, always a plus, assorted characters without much of an alibi, Jessica looking trim and efficient, lovable Seth. We find out about the backgrounds of a doctor, a businesswoman, a young opportunist and his wife, but practically nothing about the victim until the very end, so it's anybody's guess why poor Dixon was knocked off, if he didn't accidentally drown. Jessica, Amos and the Juniper Lake sheriff (wonderfully played in low-key style by J. D. Cannon) don't seem to exert themselves much to learn a thing about Dixon or any enemies he might have made.
The end is a big anti-climax. Don't want to give it away, but really, ask yourself, if you were Lt. Det. Barney Kale, would you have trekked to Juniper Lake to finish the "unfinished business"? HOW stupid is Kale? '
