A good whodunit should have a bit of originality in the plot, and the solution should not be too easy to guess. And it shouldn't be too long. Under those criteria, this last episode in the "Crime Doctor" series holds up very well.

The plot is about a convicted arsonist who gets an early release from prison. The agent of his good fortune is the Crime Doctor himself, who believes the man is guilty but considers him redeemable. Ignoring the advice of the doctor and others, the man rashly sets out to prove his innocence. Soon he's in bigger trouble than ever, and it all looks just a bit too convenient.

Warner Baxter, whose career was drawing toward an end, is considerably grayer than in his previous "Crime Doctor" films, and he doesn't get involved in much action. But he doesn't seem frail. He has a stylish presence that compensates for the movie's fairly spartan production values.

The two women in the ex-con's life, who turn out to be important to the mystery, are played by Lois Maxwell and Adele Jergens. Maxwell is better remembered today, because of her later role as "Moneypenny" in the James Bond films. But in 1949, Jergens, a former burlesque queen, was a much bigger name in movies. She certainly gets the more glamorous treatment here.
