Curious film noir which steals narrative riffs from many other genre classics (I Married a Dead Man, Suspicion, etc) but contains quite a startlingly original premise for the period about the ongoing ordeal of a distressed woman (Valentina Cortese) rescued by American forces from Belsen.
She steals the identity of her deceased friend from the camp in order to get to America where the the dead woman's son stands to inherit from the wealthy family who took him in. The survivor marries the family lawyer (Richard Basehart). But does he plan to kill her to seize the money for himself?
The luxurious house of shadows on Telegraph Hill has ominous presence and a classic noir look. The secret old playroom with a hole blasted through a wall reveals a cliff edge overlooking San Francisco, suggestive of the guilt and fear of discovery that hides in the imposter's heart.
This is presented in a semi documentary style (incorporating newsreel of the camp) through flashback. 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 lesser known Robert Wise film, but very suspenseful.
