Anyone answer this stinker?

I have no idea but this looks promising:

Marked Woman (1937), 99 minutes, D: Lloyd Bacon
An urban melodrama, based on the real-life story of NYC vice lord Charles "Lucky" Luciano. It is the story of a nightclub hostess ("prostitute") Mary Dwight (Bette Davis), who works at the Club Intime, owned and operated by a notorious gangster Johnny Vanning (Edward Ciannelli). Special prosecutor, district attorney David Graham (Humphrey Bogart) tries to convince Mary to testify against her crooked boss - first for murdering one of the debt-owing customers Ralph Krawford (Damian O'Flynn) and then for killing her innocent sister Betty (Jane Bryan). To threaten and scare her, Vanning scars Mary's face, making her a "marked woman." This convinces her to finally testify in court with other hostesses to convict him.

Thanks boomerang, someone on another site has suggested the real life person might be Annie Oakley so I have plenty to sift through, if I find out one way or the other I'll let you know.
