70s/80s Detective movie, 'Let me show you how I used to make a living'

I saw this one decades ago and it cropped up on TCM some months ago.  Looks like a made for TV or direct to video, a hard-boiled honest cop is protecting an attractive black woman in her apartment.  At one point she says 'Let me show you how I used to make a living' and changes into a costume and starts to strip.  Sadly, they are interrupted before she gets too far.

Bump.
