"Sluggish" is the key word here. In the movie's sluggish first hour, director Jacques Deray does little except perfectly capturing the atmosphere of summer heat - the blazing sun, the rippling water of a pool, the sensuousness of the almost-naked bodies....while the characters say things like "I'm going to shave", compete in swimming and go shopping. Because this is also supposed to be a thriller, a murder must eventually come - and it comes after 80 minutes, in an atmospheric and memorable, but also poorly motivated scene. The aftermath of the murder is as sluggish as its preparation. It's really a well-made film, but maybe TOO suggestive - the audience has to fill in too many blanks. Another problem, already pointed out by a previous reviewer, is that Birkin (the young girl that catches Delon's eye) is a lot less attractive than Schneider (the woman he already has by his side) (**1/2)
