Perhaps not a noir, strictly but a very effective b/w thriller with great use of San Francisco locations. Valentina Cortesa is excellent and very believable as the lady who makes her way from the concentration camps to the house on Telegraph Hill. Richard Basehart is also very good in a complex role as her husband. But mention must also be made of William Lundigan and the terrifying Fay Baker. Even the kid is acceptable! This is a most involving and atmospheric picture, perhaps with shades of 'Notorious'. Great dialogue helps keep one involved throughout and there are certain scenes, for instance, the orange juice sequence that are positively thrilling. Excellent.
