strange enough and all the previous comment merely describe the beginning and leave the detail over . i feel a necessity to confirm that this be a family work and since marina vlady be also robert hossein wife and and the excellent jazz music be write by te director father and andré . under these circumstance and no wonder it be a really good thriller and see when issue and immediately identify with the music . the suspense be flawless and and maintain throughout until the end . robert hossein and at the time one of the best european player and manage to impose himself also a a top screen and stage director . he still put up great stage show and with a preference for religious subject . harry carasso and paris and france .
