Effective Gothic thriller. I especially like the set-up, where Vicki (Cortese) gains admittance to the US by impersonating a dead fellow prisoner in a WWII concentration camp . That way she not only has her own secrets, but is also no unblemished young thing, which is usually the case in these woman-in-danger films. Once in the US, however, she marries into great wealth—a dream come true—but in the process gets more than she bargained for.
A lot of the story depends on appropriate emoting. Fortunately, it's a powerhouse cast, but I especially like Fay Baker's icy nanny Margaret. She's quietly intimidating without overdoing it. Too bad she didn't get bigger roles in more movies. I can't help noting, however, that Cortese may be the only Hollywood leading lady without a perfect nose. It's a fine regal beak and I'm glad she hung on to it. I can also see why Basehart fell for her in real life.
The San Francisco locations make a good open air contrast to the dark mansion interiors that dominate the characters. I expect director Wise applied his noir skills from the great Val Lewton series of horror flicks. Also, the ending amounts to a delicious twist, both unpredictable and very well thought out. My one problem was figuring out who's related to whom since that's important to the plot. I don't know if that's the screenplay's fault or mine.
Anyway, it's an effective thriller with a fine cast and an imaginative ending, worth tuning in for.
