Choosing a title

Hi all,

I absolutely hate choosing titles for my work as I never know what works. So I've come here for more amazing advice. My recently completed piece is about a domestic abuse relationship involving a female who is a successful businesse woman having an affair with a mixed race male. There is because of the storyline a lot of rape and quite a few deaths. I initially thought of the title 'What he doesn't know can't hurt me' but since he hurts her anyway I don't feel it works. I then thought 'Does he know?' is this a good title idea or cab you think of better? Thanks in advance!

Kind regards Vicky
