A fine mashup of the 'woman in peril' genre and film noir. Valentina Cortesa is a concentration camp survivor who assumes the identity of her deceased best friend. See, the friend sent her baby to live with a long lost rich aunt in America. When the aunt turns up dead she can inherit the fortune and the titular mansion, right? Not so fast. The creepy lawyer who's the executor of the estate (Richard Basehart) has other ideas...like, um, murder. Some great thriller set-pieces and the on-location photography of early '50s San Francisco make this an engrossing watch.
