Radio personality "The Fox", who solves fictional crimes over the airwaves, is fingered by the police to be a real-life serial killer known as the Constant Reader after one of his radio plays features a clue that matches letters delivered by the actual criminal. Third "Whistling" film for Red Skelton and Ann Rutherford, following 1941's "Whistling in the Dark" and '42's "Whistling in Dixie", has some funny, inventive slapstick scenes mixed in with a lot of outright silliness and corn. An early bit involving a freight elevator is priceless, though the double-header climax (first at Ebbets Field, later down on the docks) is fairly dire. The ladies (Rutherford and the spirited Jean Rogers) are both terrific foils for Red, but chauffeur-sidekick 'Rags' Ragland is a lead weight. Plenty of chases and sight-gags, lots of fast dialogue, a surprising (and funny) gay joke, plus the Brooklyn Dodgers themselves make this a must-see for Skelton's fans. It moves along quickly enough, but the last reel doesn't give the supporting players much to do, and no one bothers to explain why the New York police force are so consistently inept. ** from ****
