This rather claustrophobic British mystery opens on the death of a chronically ill woman, Edwina Black during Victorian/Edwardian times. She is a wealthy woman, and leaves behind a large estate. We quickly learn that Edwina's widower, Gregory, and Edwina's companion, Elizabeth (Geraldine Fitzgerald) are lovers and plan to sell the house and move to London as soon as possible, marry, and honeymoon in Venice. Both Gregory and Elizabeth have no money of their own. There is also a housekeeper/nurse who has been with Edwina for years who sees what Gregory and Elizabeth have been up to, and is suspicious of their involvement in Edwina's death. Soon her suspicions have her wagging her tongue to the village folks, and Scotland Yard is brought in to investigate Edwina's death. Post mortem shows she died of arsenic poisoning, not the heart attack originally thought to be the cause of death. And so the. Inspector (Roland Culver) begins digging, and Gregory and Elizabeth are stuck there in this dark house full of bad memories until the investigation is over.
This film is rather claustrophobic, with almost all of the action taking place in the large Black estate. You never actually SEE Edwina. The short time she was alive she was behind the door of her bedroom. So all we know about her we get from listening to the three people who lived with her. From the beginning Elizabeth has felt Edwina is haunting the house, looking for a way to get back at them. And on top of it all, now both Gregory and Elizabeth are wondering if the other actually did poison Edwina, and would they be next if the actual murderer wanted to hang the killing on them.
Roland Culver is very good as the inspector. Where do all of these British films come up with such thorough cops with nerves of steel and great observation powers? For once, this is a film that works for Geraldine Fitzgerald. I never felt that Warner Brothers quite knew what to do with her. I'd recommend it.
