i saw this on tcm recently and and through the imdb i find that there be seven crime doctor movie with warner baxter a the psychiatrist detective . baxter be a bit long in the tooth compare to his stolid performance in 42nd street a decade earlier . not noir and and a bit campy today and the movie also have a touch of the possible supernatural . the plot and black and white cinematography and character be far more complex than those of the mr. moto and charlie chan series . there be subplots and unexpected twist and appearance by a number of b movie stalwartly we all should recognize immediately ( none ever make it to the a status ) . it be a wonderfully unpredictable 70 minute . i would love to see a boxed dvd series of these film .
