This film is not as well known as the earlier Universal flick The Spider Woman; and that's because this one isn't a part of the Sherlock Holmes series, isn't nearly as good, and actually has nothing at all to do with spiders. The plot focuses on a young girl that goes to become a nurse in a blind woman's house. However, it turns out that the woman is not really blind and is actually taking blood from the girl in order to feed it to her plant, which ties in with some plot about murdering cows. Aside from the fact that this film features Gale Sondergaard, I really don't see any similarity to The Spider Woman at all - she doesn't even reprise her role! The name, therefore, is just a cash-in on the success of the original. It's the sort of trick I'd expect from Italian films of the seventies and eighties, but not something often done by Universal studios! You can't blame them, though, as the film really does have no other selling points. It's a poor and rather dull tale. Nothing of interest happens for the entire duration, and I'm not surprised that it only runs for about fifty eight minutes. Overall, there's really no reason to track this film down - Sherlock Holmes fans will not be impressed!
