The Creeper is a solid episode from the first season of the half-hour Alfted Hitchcock Presents series. I've heard it done as a radio show and it worked well in that format. It also works nicely on television.
A killer is on the loose in a low rent neighborhood of Manhattan during a heat wave. His victims are blonde women and no one knows what he looks like. He could be anyone. The story focuses on a squabbling couple, a laborer husband, and shows the stress that his blonde wife is under when he leaves for work one day.
An older woman in the building is of little help. She offers to stay with the younger woman but her basic obnoxiousness if off putting. The young wife passes. Then a friend of her husband turns up and starts giving the housewife a hard time (they'd apparently dated prior to the woman's marriage to her current husband). The friend, a journalist with some inside knowledge about the case, is too weird and aggressive to be good company, and besides, his presence is unsettling. Off he goes.
What transpires afterward, while I wouldn't go so far as to say it was telegraphed early on, certainly comes as no surprise. This kind of suspense tale is as a type as old as the hills. One doesn't watch such things to learn about human nature or expand one's horizons intellectually and emotionally. The central conceit is far from brilliant. It's appeal, it's considerable charm, is watching how it's done,--well or badly, stylishly or ponderously. I'd say that The Creeper is far more stylish than ponderous. It's helped by its director, the capable Herschel Daugherty, and by its small cast. The Creeper isn't one of the sharpest or best written Hithcock half-hours but it's competent and satisfying for those who liked a good chill but who don't want to want to catch pneumonia.
