Alfred Hitchcock Presents Season 1 Episode 18

Ray Bradbury's theory that a temperature of 92 degrees Fahrenheit is dangerous, and that more murders are committed at that temperature than at any other time, had been voiced before this - not only in his original short story, but in the dialogue of the 1953 science-fiction movie "It Came From Outer Space", which Bradbury was involved in writing. Here, the two elderly bachelors who have devised this theory watch in horror as the slatternly Mrs. Shrike (a nod to Nathanael West?) is driven by her irritation with the heat to become more and more annoying, and they just know someone will want to murder her. She's not just "an accident waiting to happen" - she's a born victim, for all her aggressiveness.
