If you have to choose between going too far or being too late, always choose too far.
Marion Pallas is the plain middle sister, the raven between two tropical birds, and that is how the ladies in 1920's London high society treat her with their malignant whispers and snide comments. When Marion exacts her revenge, her misdeed launches a plot to save her involving a motley crew of characters including a Canadian playwright and his theatre company, a notorious gang of female thieves, a countess's duplicitous lover, and a very devoted and decidedly unconventional aunt.
If only they can shake the relentless investigator who wants to clip Marion's wings.
