The Upturned Glass (1947)

Surprisingly good hitchcockian thriller concerns a doctor (James Mason) who falls in love with the mother of one of his patients, they have a brief affair and shortly after its over she winds up dead from what appears to be either a suicide or an accidental fall. The doctor suspects it was murder and launches his own investigation eventually centering on his late lovers sister-in-law whom he plans on killing in revenge. Film is solid throughout but runs about an act longer then I had expected, it is in this act that the film takes on a truly memorable character and proves it has a psychological sophistication you might not expect in a movie of its time. A sadly obscure film, but well worth finding. 4 out of 5.
