Probably as a reward for her energetic performance in Torchy Plays with Dynamite, pert Jane Wyman was given another Glenda Farrell-like leading role in Private Detective. Wyman plays gorgeous P.I. Myrna Winslow, the principal rival of male gumshoe Jim Rickey (Dick Foran). The case at hand concerns the murder of a millionaire, with the dead man's wife and her boy friend as principal suspects. Also adding to the intrigue is an enormous trust fund, set up in the name of the millionaire's adopted son. A goodly portion of the film takes place in a deserted mansion at midnight, with Myrna snooping where she shouldn't. The finale finds Myrna and Jim joining forces to capture the real murderer in a well-staged donnybrook. Private Detective runs 57 minutes-and "runs" is the right word here.
