The conclusion to this involves a psychopath who has been preying on young women and getting their husbands to take the blame. It's incredibly complicated, but a finger, cut off is at the center of several homicides. It all starts with this nut case pretending to be a cop and meeting the woman of his dreams. Her escape from his clutches sets a series of murders in motion. Well done and suspenseful, even though we are pretty aware of the bad guy through the whole thing.
