Tightening the screws of a two hour kidnaping the author of The Desperate Hours (1954) manages anguish and ordeal with his clock-ticking presentation of the events as they affect the Elgins, parents, of Julie, 17, abducted by Nolan, a sideburn kid of her own age. Terrified by Nolan's threats, the Elgine do not call the police until the last moment; drunk with his early success Nolan is ready for rape and murder when things go wrong; humbled and grateful when she is rescued Julie is ready for another chance to prove her love for her parents. Chilling -- plot and characterwise.
