The first half is a lot of ho-hum setup, unfortunately the payoff isn't spectacular enough. It's good, the tension builds nicely and there's some ambiguity. It just doesn't have enough "oomph" to it. It's also too bad that nothing much is done with the Holocaust survivor angle, or even the stolen identity business. Cortese is excellent, though... the film was meant as a showcase for her, and does that job well. Basehart is fine, too, although I'm not a big fan of his to begin with.
