Un soir sur la plage (1961)

Un soir sur la plage is relatively interesting; the cast includes highly talented Jean Dessailly, Martine Carol, a cast against type Michel Galabru as the cop.The biggest surprise is sixties starlet Daliah Lavi as a simple-minded nymphomaniac girl who is murdered on the beach. The story is essentially a whodunit: in Martine Carol's house, there are many people (too many people actually) and they all have a reason to get rid of her.
