Review of The Scarlet Clue

Methodical Charlie Chan feature. Little suspense. No intrigue. But, I still find it cool to watch. Chan is called on to investigate the murder of a suspect in a plot to steal top secret information concerning the Government's planned use of radar. The investigation takes Chan to a radio station, where he has a studio full of suspects and knows one of them is a killer. But who...the station manager(I. Stanford Jolley), a soap opera owner(Virginia Brissac)or maybe one of two actresses(Janet Shaw and Victoria Faust). Helpful or not, Charlie has the help of one of his sons(Benson Fong)and his comical chauffeur(Mantan Moreland). Right away we know that Chan's first major clue is a shoe print. But, there are others of course...this is a Charlie Chan mystery isn't it?
