Curious film noir that steals narrative riffs from other films constantly (I Married a Dead Man, Suspicion, etc) but contains quite an original theme for the time about the ongoing trauma of a woman rescued by American forces from Belsen.
Valentina Cortese plays the damaged woman who takes up the identity of her deceased friend from the camp in order to be allowed to move to San Francisco where the the dead woman's son stands to inherit a fortune from the wealthy family who took him in. She marries the family lawyer (Richard Basehart). Could he be trying to kill her in order to seize the money for himself?
The look of the opulent family home on Telegraph Hill is a typically ominous presence in the film. There's a nice touch with a hidden old playroom with a hole blasted through a wall that reveals a cliff edge overlooking San Francisco, suggestive of the guilt and fear of discovery that hides in the woman's heart.
The film is presented in semi documentary style (incorporating newsreel of the camp) through flashback with Cortese's narration telling the story. Cortese is sympathetic in a role that puts her on screen for the whole running time and is convincing as a woman who has suffered profoundly. It's a little known film from Wise but very suspenseful as we fret over whether the imposter will be rumbled.
