Visitors in Paradise begins with a man standing over a dead woman and then fleeing the scene to supposedly chase the person responsible. He is stopped by authorities, and when they inquire about the blood on his shirt he tells them he had a nosebleed which they don't buy and promptly arrest him. Some time later, Quincy (Jack Klugman) and Danny (Val Bisoglio) arrive at a mountain lake hotel for a vacation where they intend to relax and go fishing. They are approached on the lake by a young woman who pleads with Quincy to reopen the investigation into her mother's death which her father has been convicted for. Quincy feels bad for her and puts his vacation activities aside to look into the case further.
While he finds that some aspects of the investigation were inadequate, the evidence against her father, which includes the blood-stained shirt, is quite compelling and he feels there is nothing more he can do. As he is about to wrap things up, the behavior by others in the town goes from unfriendly to violent as he is forced off the road, his vehicle is vandalized and there are threats of physical harm. Danny has a similar encounter while out in the boat which is a little more humorous. These events convince Quincy that a cover-up is taking place which leads him to investigate further and order more testing on the blood-stained shirt that the convicted man was wearing.
Overall I found this to be a very good episode with an intriguing plot and some good guest stars. Look for Jamie Lee Curtis in a brief but comical appearance as well as Pernell Roberts of Bonanza fame as the sheriff. In a nod to Pernell's history on that show, during the final scenes his sheriff character is listening to an admission from one of the complicit who says they were supposed to get a "Bonanza" from the oil gusher that never panned out which was cute.
My only complaint is that this episode utilizes the old go on a vacation and boom there's a murder as well as the whole town is out to get rid of me ploys which were overdone by these types of shows of the time, but as long as that doesn't bother you it is quite enjoyable.
