The hefty feline sleuth Midnight Louie and his human partner, Temple Barr (whom Louie refers to as "a grown-up Nancy Drew on killer spikes"), accompany Temple's outrageous landlady, Electra Lark, to a Red Hat Sisterhood convention. Trouble ensues when Electra is accused of murder, and it's up to Louie and Temple to get her out of the jam. The most likely suspect is another one of the convention attendees, or could it be any of the protesting Black Hat Brotherhood?
