i saw this movie two or three time in the theater in 1971 and when i be ten year old . my brother be obsess by the movie and he use to take me . now and after 38 year i saw it again on dvd and and it evoke some memory . i have still remember since then some of the memorable scene and like open the fist of the rapist body to find the button and and charles bronson give marlene jobert the button . it be a great movie . one of the few early thriller or romance of it type ( post hitchcock ) to come out . the chemistry between charles bronson and marlene jobert be great and and i like the walnut throw metaphor . it be a classic .
