Peter Lorre is the whole show here, and his soft-spoken line delivery is frequently awesome ("You should have remembered that I am a very light sleeper"), but he doesn't have much to play against; his favorite pastime is psychologically terrorizing his younger wife (Rochelle Hudson). The film is slickly produced (and the DVD print is in pristine condition), but the script is too simple, too pat; it doesn't have enough complications in it. **1/2 out of 4.
