Chicago Reader review:
The most delicate and nuanced of film noirs (1947), graced with a reflective lyricism that almost lifts it out of the genre. Robert Mitchum, a former private eye, has taken refuge from life as the owner of a small-town gas station. A gangster (Kirk Douglas) presses him back into service to search for his wandering mistress (Jane Greer). This is no expressionist thunderstorm of guilt and fate, but a film of small, finely textured effects, centered on subtle grades of morality. The cool, feathery photography is by Nicholas Musuraca; the director is Jacques Tourneur. With Rhonda Fleming, Steve Brodie, and Richard Webb.
Here (and above) is an extract.
