It's obviously an old Hindi suspense movie

I have to choose between kaaanoon, kohraa, mahal, woh kaun thee? anita, hamraaz and may be a few more like these.

The only additional clue is that it is a black and white movie and not colour so it is likely to be a movie made before 1970.

I will attempt this later during the day.
