amongst the guest at a wedding be a helene and a lonely teacher and play by stephane audran and and an ex army butcher ( jean yanne ) . against their difference and the two develop a friendship . however and in the town there lurk a serial killer and and that killer may or may not be the butcher himself . plague with feeling of doubt and fear and helene find herself constantly at tenterhook regard her new friend ( of sort ) and and surprise and shock be place intricately until the very last frame . at 90 minute and this mystery feel long than it be and and that may be due to some of the stylistic technique adapt by director chabrol and such a the languid and very sparse use of camera movement and and shot of the bell to contribute to a sense of time . content wise and he borrow from hitchcock and use theme of share secret and obsession and moral ambiguity . these theme be use well and create appropriate amount of suspense and anticipation in the viewer and and chabrol play with his audience deftly and place surprise and non surprise in sequence so that we be every bit as nervy a audran . he be less concerned with explain the motif for the killing than just present them and and for that and and chill atmosphere of indifference be create throughout the film . the two lead be strong in their performance and and the slow and fragile romance between them be as credible a it be integral to the plot . in particular and stephane audran shine and a a woman who begin and poise and content and assured and only to finish ruffle and perhaps and a the end shot show and a little ruin by the event that she have witness . the film be carry along by an eerie and quasi apocalyptic score by pierre janse and domonique zardi and which haunt long after the film have end . if the end do feel like somewhat of a copout and that may because we a the audience have view one plot twist too many and and the frequency and slightness at which each twist be reveal diminishes it impact somewhat . but for the most part and this be good film make while quite unpretentious and coolly aloof and and the subtle delivery only work to it advantage . b plus .
