Produced by RKO as a vehicle for Hedy Lamarr, this little-known mystery (1944) ranks alongside the major works of director Jacques Tourneur, whose mastery of tone and feeling was evident in genres as diverse as horror (Cat People), western (Canyon Passage), and film noir (Out of the Past). At the turn of the 20th century, a Manhattan doctor (George Brent) is pulled into the unhappy marriage of a wealthy couple, and after falling in love with the mentally fragile wife (Lamarr), he begins to suspect her controlling husband (Paul Lukas) of murder. The densely layered plot doesn’t always add up, but in the end that enhances the sense of mystery, which Tourneur sees not as some narrative puzzle to be solved but as an irreducible aspect of human experience.
