It was perhaps inevitable that Monogram's "Teen Agers" series would get around to a murder mystery: after all, wasn't Monogram the home of Charlie Chan, Mr. Wong and The Shadow? Campus Sleuth finds perennial co-stars Freddy Stewart and June Preisser cast as coeds Freddie Trimball and Dodie Rogers. When a magazine photographer is murdered, Freddy and June set about to solve the murder, with the dubious assistance of their college chums Lee Watson (Warren Mills) and Dodie's sister Betty (played by Noel Neill, who later gained TV fame as Lois Lane on Superman). While Inspector Watson (Donald MacBride) fumes, fusses, and jumps to all the wrong conclusions, our young heroes and heroines track down the killer -- who happens to be one of the film's musical guest stars! The film's biggest "mystery" is how the producers managed to pack a murder story, a plethora of comedy relief and four musical numbers into 57 minutes.
