“The Ladybug Song” is the third book in the delightful Isabel and Alma Trumbo Cozy Mystery Series by Ed Lynskey. The story revolves around Phyllis Garner, a kooky and funny bag lady who refuses to accept her best friend Ladybug Miles’ death as an accidental drowning in the Coronet River. Despite the blustery, know-it-all Sheriff Roscoe Fox officially ruling it an accident, Phyllis believes it was murder.
