Classic Horror Films - Day 18 (SISTERS - 1973)

Danielle Breton (Margot Kidder), a beautiful young model, meets an attractive young advertising rep on a Manhattan game show and he escorts her to her home to Staten Island. The next day, her neighbor Grace Collier (Jennifer Salt), a local reporter, witnesses a bloodbath of violence in Danielle's apartment - and can't get anyone to believe her. With the help of a private detective, Grace attempts to solve the mystery. I saw  this film years ago and remembering it being very good. Great performances by the two lead women - Kidder and Salt. One of the first films directed by thriller/suspense expert Brian DePalma. Does have a cool twist ending too.
