Reporter Sue Walker has too much inside information on the local gambling rackets to suit her sweetheart, Detective Lieutenant Jerry Brown, chief of the police Homicide Squad. When the call comes in that there has been a killing at Lefty Ross' place, a notorious gambling joint, Jerry is peeved when Sue beats him there. He discovers that gambler Jimmy Clark was killed as he answered a telephone call, and his body is riddled with bullets but Jerry can't find any weapon. Sue is amazed to see Gloria Cunningham there. Gloria's father is one of the town's leading reformers and she is engaged to District Attorney Richard Sutton. Ross decides to give Sutton all the information he needs and makes an appointment to go to Sutton's home. Once there, Ross is called to the telephone before he can give any information, and is killed in the same mysterious manner as Jimmy Clark. The only people aware of the appointment were Sutton's secretary, Tyler, Gloria and her reformer father, and Sue Walker, ... Written by Les Adams <longhorn1939@suddenlink.net>

Murder over the... phone
3 April 2014 | by binapiraeusSee all my reviews

Now, don't expect too much from this Poverty Row 'cheapie'; it was made by PRC, one of the poorest of the poor - and yet this murder yawn DOES have some very nice points for fans of the genre: a quite realistic depiction of the gambling racket with all its crossing and double-crossing, a pretty inventive murder method, and a VERY entertaining 'love-hate' relationship between a tough cop and an even tougher girl reporter, who's always a step ahead of the police...

You think you've seen all that before? Well, but probably not in THIS literally DRASTIC way: Sue, who's a true-bred police reporter and would risk ANYTHING (even her life) for a hot murder headline, even goes so far as to knock her flatfoot 'boyfriend' out when he wants to keep her from digging deeper into that dangerous gangster story!! All in all, Grace Bradley as Sue is the very core of the otherwise pretty average movie - one of the greatest (and yet one of the least known to the wider audience) reporter heroines of classic crime movies - which leaves us all with a REAL mystery: WHY didn't she become a big star?? She would most CERTAINLY have deserved it.
