Four Days Wonder is adapted from the A. A. Milne novel of the same name. New Universal contractee Jeanne Dante stars as precocious 13-year-old Judy Widdell, a devoted fan of dime-novel detective stories. When a real murder occurs in the vicinity, Judy insists upon playing sleuth, dragging teenaged astronomer Tom Fenton (Kenneth Howell) into her Sherlock shenanigans. It's no trick for Judy or Tom to out-guess dimwitted police detective Duffy (Walter Catlett), but the murderer isn't so easy to flummox, and for a while it looks as though our heroine will never reach adulthood. As it turned out, star Jeanne Dante, a youthful veteran of the Broadway stage, was something of a four-day wonder herself, disappearing from films not long after this one was released.
