This is another episode dealing with the possible abduction and murder of a child. A girl has had a row with her mother and her live in boyfriend. She has a paper route and during the delivery of the papers, she has disappeared (the last two houses were never approached). Frost's charm (if you can call it that) is his respect for people who are down on their luck or have situations over which they have little control. He comes across some rag tag types whose appearance would make a lesser series use them as stereotypical villains. The most consistent "villain" is Mullett, Frost's supervisor, who wears his jealousy of the unconventional detective on his sleeve. In a second plot element, an attractive young woman and her husband have been receiving weird phone calls and have experienced acts of vandalism, including chlorine poured into their fish pond, killing the koi that live there. Frost is confronted by the husband because he doesn't think the police are doing anything. The problem is there is absolutely nothing to go on. A third element is that Frost's insufferable sister in law has come to stay with him following his wife's death from a prolonged illness. She takes over. She makes long distance calls to the states to talk to her husband about trivial things, costing Frost large sums of money, and she is constantly on his back about every little thing. Excellent second installment in a series I hoped would go on forever.
