I liked this movie and I love Victoria Principal. She's such a great actress! The plot was pretty good but there are a few plotholes, as there are with most films. One that comes to mind is right after her husband is murdered and the police are in her house questioning her about the killers, her friend is seen cleaning up after the birthday party. The friend spots the killer's necklace on the kitchen floor and picks it up, putting it into the jewelry dish on the counter. In real life, nobody would have even been allowed in that house because it was the scene of a homicide. Police are very strict about that! They certainly never would have allowed her there, much less to be cleaning up possible evidence. The police missed the necklace clue because of this woman unknowingly picking it up. I did enjoy this movie, though. Worth watching!
