Time Out review:
Malle's first feature, a straightforward but classy thriller about an ex-paratrooper's attempt to dispose of his mistress' tycoon husband in a perfect murder. It became associated with the early excitements of the nouvelle vague mainly through the performances of Ronet (playing a prototype of the disgruntled Vietnam veteran) and Moreau (who does some moody solo wandering in the streets searching for her missing lover). The ingenious plot, using a malfunctioning lift as its deus-ex-machina, has one carefully plotted murder conjure another as its shadow image. But the cement holding the film together is really the splendid jazz score improvised by Miles Davis.
Here (and above) is an extract.
