"It would be you," Inspector Piper nods the moment he turns and sees Hildegarde Withers arriving on the scene. "It's gotten so, Hildegarde, a person can't be killed within the city limits without your showing up."
This is, indeed, the fourth murder case on which Miss Withers assists, critiques, leads, follows, and just generally offers suggestions to her crusty detective friend. James Gleason's Oscar Piper is once again easily chagrined but grudgingly respectful of Miss Withers' detecting skills; Helen Broderick takes on the role of school teacher and amateur sleuth Hildegarde Withers for the first and only time. This Withers is a bit less tart and somewhat more conscious of her own wittiness than the earlier Withers (as portrayed by Edna May Oliver). Broderick and Gleason quickly establish a rapport and relationship that—as in the earlier films in the series—is easily our primary reason for watching.
The plot involves the death of society girl Violet Feveral, played (albeit briefly) with delicious nastiness by Sheila Terry. Suspects abound—this Violet was, in the best whodunit tradition, wildly unpopular and had handed out insults and injuries to numerous other characters in the hours and days before her death. The familiar faces in the lineup of suspects include Louise Latimer as a sister to the victim; John Carroll as a family employee; and Leslie Fenton, who is quite good as the nervous ex-husband who has just been mysteriously released from jail. Willie Best stands out in his usual thankless role as a stable boy who may have a clue or two; his deadpan delivery when answering questions (What was he doing in jail? "Shooting craps." No, what was he in jail for? "Shooting craps.") squeezes the maximum out of a role that's otherwise a lame stereotype.
The mystery itself is not particularly inventive or suspenseful; however, the story moves along briskly and the actors and script are competent if not brilliant. The interaction between Gleason and Broderick is clearly presented as the center of the picture—and that relationship between a couple of pros is a lot of fun to watch. (One example: Oscar suggests that the murder was a "crime of passion," to which Hildegarde snaps, "Oscar, don't you think we'd better try to keep this case clean?")
