The Plot Thickens

Inspector Oscar Piper (James Gleason) has a baffling new case on his hands when John Carter (Richard Tucker) is found dead in his study by his butler, Kendall (Arthur Aylesworth). There are several suspicious people in Carter's circle. Alice Stevens seems to be the last person to have seen Carter alive; her boyfriend, Robert Wilkins, was seen arguing with Carter by a cop; and there's a mysterious stranger with a French accent whom Kendall overheard speaking with Carter before the crime took place. The further the investigation moves along, the more baffling the mystery, but Oscar has a secret weapon that may help him crack the case: schoolteacher/sleuth Hildegarde (ZaSu Pitts) Withers.

Pitts and Gleason play very well off of one another. ZaSu is really good as Hildergarde, and though she's not as distinctive as Edna May Oliver, she gives her own spin on the character, and comes across a bit dizzy yet intelligent and self-assured, and witty. She appears to be inattentive and "all over the place", but in reality she's analytical and doesn't miss a thing. As one reviewer rightly said, it's Columbo style of misdirection.

As for the mystery, it's quite good, has plenty of twist and turns, interesting suspects, a neat buildup to the murder, and a satisfying denouement, though it can be a little convoluted at times.
