Psychological suspense with hints of paranoia is a Windsor specialty, and here she keeps you wondering along with Michael Thorne, 17, and just released after two years in an institution. Mike comes home to his grandparents with all sorts of questions about whether he is confused, deranged, or even guilty of the murder that occurred just before he was sent away. Then another possibility becomes more and more likely: though no one will believe him, perhaps he did see a man push the girl who turned up murdered that night in the park. And maybe that man is now out to kill him. There are other questions, such as what happened to the letters Mike's old girlfriend says she sent him, and whether he can trust the writer who says he wants to clear him. Seeking the truth about that unsolved murder, Mike finds himself also tracking down the truth about his own parents. If the solutions to both puzzles mesh a little melodramatically, the search has focused on our reading of the characters. They're worth watching.
