A letter comes in to ask for help in finding the missing brother of a woman. Why not just go to the police for what seems to be a simple matter? That’s the thing Dan wants to know.
Being just curious enough, Dan talks the matter over with the gal, then she suddenly seems to abruptly part company and go her own way. Dan is already hooked, and begins to do his own snooping. He confronts a tough guy who wants to join forces, and claims he knows secrets about the woman. He just wants to know all that Dan does, but is tight lipped on revealing much. The tough guy doesn’t want to share information other than to say that the woman isn’t who she says she is.
It’s back for a meeting with the aledged sister who stands to share in a large inheritance. She is insistent that she is telling the truth, and together they go visit the tough guy, only to find his body. I don’t know about this Dan, remember that hard boiled detectives such as yourself just can’t trust a dame. I don’t trust her.
As Dan phones to report the murder, the woman thumps him on the head. Dan wakens to the sight of the cops standing over him. I hate to tell you so, but when will these radio detectives ever learn, never trust a dame.
The cops get on the job to investigate, and when their searches turn up little, namely that there is a sister by the name the woman gave, but the descriptions don’t fit, Dan does more poking around. He soon finds himself in more danger, as he turns up some heat, but can he count on the cops for his safety net?
Dan shares what he knows, which sounds like the mystery unravelled, but there is still no woman, or her double crossing chauffeur. The clincher comes in when Suzie comes in to remind Dan of her desire to examine the handwriting of the note that got this adventure started. It triggers an inspiration in Dan, and he races off to confront the bad gal.
He has it figured out, and has both her money, and her, over a barrel. All the twists come out when Dan is back in his office and explains all.
