This little novel is a total departure from the Dr. Thorndyke mysteries, the classic British detective novels that made Freemans reputation. The heroine is a perfectly proper but adventurous young woman named Phyllis, who takes over her cousin Charlies chambers in Clifford Inn. The presence of some of Charlies clothes in the closet gives her the idea of dressing as a man for a fancy dress ball. Unfortunately, Phyllis looks just like the charming Charlie when wearing his clothes, and this gets her into some difficulties, because Charlie is a bit of a scalawag. Phyllis as Phil gets into fights, performs heroic acts and falls in love with a man who thinks shes just his pal. Her adventures are tremendous fun. From impersonating a man to discovering mysterious trap doors, Flighty Phyllis is an entertaining glimpse at the times and trials of a wayward woman.
