"La Mort De Belle" has a modest budget and a low-profile cast (Alexandra Stewart is the only name I recognized, if I'm being honest), but it works very well both as a whodunit and as a piercing portrait of middle-aged loneliness and disillusionment. It keeps you guessing until the last few minutes, and has a double or maybe even triple-twist ending, yet the clues for each of the twists are neatly planted ahead of time. I liked this film a lot and I wish it was better known. *** out of 4.
