[Alfred Hitchcock Movie]

No "Dressed to Kill" is not it. I know the psychiatrist wore the nurse's clothing after killing her, but no that's not the one. Thanks.

I can't recall the name of one of his wonderful movies about this nurse that was a killer and at the end of the movie the nurse was actually a man. Can someone please tell me the name of it so that I can try to get a copy. Thanks!
