A murder film from 60's or 70's, Where they stage a white pair of nurses shoes under a door or curtain to make you think the murderer is their, When he is BEHIND YOU!

I know this is a totally old thread - don't know how I missed it the first time - think the poster is looking for the final scene in Dressed to Kill, I remember watching this when I was younger, terrified me, this scene sticks in my mind... at 1min 58sec you see the shoe placement being referred to...
