hi there, years ago i saw a movie on tv which was set on the european coast possibly riveria and was about the death of this man, the brother of the sister in the movie, but then a visitor came to her house on the coast with a footpath to a bathing house? by the sea and claiming to be the dead brother and proving it by knowing his favourite drink etc, and the denouement was that he was in fact the police and they thought that the brother's car crash accident was murder and that the sister did it but they needed the body and drove her to lead them to it! can't remember any actors names but very atmospheric and spooky. thanks yours in hope to end this tormenting agony!

Sounds like Chase a Crooked Shadow (1958)
