The beautiful models of a luxurious fashion salon are being fiendishly slain     one by one. The killer is a masked maniac wearing a black glove, who wants to    keep the dark secrets of the salon from being revealed. The director creates a   superb, atmospheric setting filled with horror, dread, and the kind of gore    that most American films wouldn't touch at the time. Extremely influential on  the Italian "giallo" style. Cameron Mitchell and Eva Bartok are featured.      Mario Bava---Italy/Germany/France---1964---88 mins.
