The last of three films starring Red Skelton as ace radio detective Wally "The Fox" Benton, Whistling in Brooklyn opens with Fox and girl friend Carol Lambert (Ann Rutherford) making final preparations for a trip to Niagara Falls, where they intend to get married. Of course, they've made these plans before, and true to form, something comes up to derail the trip to the altar. The something this time is Constant Reader, a murderer who delights in taunting the police by letting newspapers know about his latest victims and where their bodies can be found. Through an error on his valet's part, the police come to believe that Wally is Constant Reader, forcing him to delay his plans, go undercover and search out the killer himself. After being chased through various warehouses and creaky old houses, Wally eventually ends up disguised as a member of a bearded baseball team playing the Brooklyn Dodgers. (Leo Durocher makes his screen debut, playing himself.) All gets straightened out in the end, and even the real Constant Reader is apprehended.
