To escape war-torn Poland, a former concentration camp inmate (Valentina Cortese) adopts the identity of a deceased fellow prisoner who has a young adopted son living with his wealthy aunt in San Francisco. Cortese moves into the family's Telegraph Hill mansion and, after the old woman dies, inherits her fortune. Unknown to Cortese, however, her disguise and newfound wealth have put both her and her "son's" lives in mortal danger... The still severely underrated movie has a lot going for it. Director Robert Wise takes his time setting the scene with Victoria, letting us know how her feelings for security were formed at Bergen-Belsen. The action moves step by step, slowly and steadily building up tension in a cobweb of actual and suspected fake identities. The film is carefully photographed to create mood. The bright San Francisco days and the busy streets of the city contrast dramatically with the gloominess and tension in the old mansion. The sets and the cinematography (Lucien Ballard) are absolutely first-rate, and Robert Wise does his usual intelligent tricky work with editing to make this woman-in-jeopardy film extraordinarily compelling. The script is a mélange of classic 40s melodramas, including REBECCA, GASLIGHT and (most of all) SUSPICION, and the film's excellent use of ist San Francisco locale helps tremendously, as does Cortese's extraordinary performance as the guilt-ridden concentration-camp survivor who steals another woman's identity. Highly recommended.
