Old Movie circa 30's-40's reminiscent of Little Miss Marker. Bachelor detective, Hustler, Conman? Has young girl he begrudgingly looks out for. Probably ends up adopting. He's Fedoraed, & mustached, helped by woman of romantic interest. It may be a comedy or comedy drama. leading man of the moment but not a name you hear anymore. And it's not William Powell or Bob Hope.
