Ida Lupino plays Helen Gordon a widow living in a great big house who takes care of children after school. We see her being kind to the children, and teaching them. Loving them. She has a big heart. She takes care of an old lodger as well. She’s a practical person, but also a bit scatter-brained and not very good at the housekeeping.

One day a man pops by. He says he’s in need of work and he’d be happy to help around the house. His name is Howard Wilton and he’s played by Robert Ryan. She says she’s got plenty of work for him to do and hires him on the spot.

What she doesn’t know, but we do, is that Howard is mentally unstable. We watched him at the beginning of the film working for someone else, someone we saw lying dead in her cupboard. Someone who, when Howard saw her dead, caused him to flee in terror.

The film builds the tension slowly. Because we know Howard is unstable we know he will eventually turn violent towards Helen, but the movie is in no rush to get there. At first, Howard exhibits some little quirks towards Helen. He’ll say something a little odd, or do some little something out of the ordinary. He might even call attention to it but Helen treats him like one of her kids.

As those quirks turn more sinister she’s still polite, still kind. She should just run, but she doesn’t want to hurt his feelings. When she finally realizes she must get out, it is too late. Howard keeps her from leaving.

The movie never quite boils over in the way I wanted it to. The tension stays on a low simmer, and I wanted it to explode. But the filmmaking is good. Ida Lupino is wonderful in everything she does and she’s terrific here. Her company The Filmmakers produced it. She was an extraordinary woman, I recommend reading up on her sometime.

Robert Ryan likewise is quite good. He’s always good as the heavy. There was something menacing about his presence.
