After a royal prince is assassinated at the Tower of London, Kitty Worthington is asked to investigate. The murder seems to be the work of a madman who soon makes her his next target. Can she catch the killer before she loses her head as well?

London. 1923. Excited about her new direction in life, Kitty Worthington motors about London in her spiffy new roadster. Granted, finding purloined Poodles and lost Labradors may not be what she envisioned, but they keep her busy enough. At least, there aren’t any bodies dropping at her feet.

But then a royal dignitary loses his head at the Tower of London, and she finds herself embroiled in yet another murder investigation. The suspects are endless. Could it be the wastrel son? The betrayed wife? The devious cousin? The ghost of Anne Boleyn?

With the help of her ace team, comprised of lords and ladies, her maid and chauffeur, and her ever flatulent Basset Hound, Sir Winston, she sets out to solve the mystery. But there's a madman on the loose who seems equally at home among the glamorous world of British high society and London's dark underbelly. If she wants to catch the murderer, she needs something more, someone who knows all about the royals. And that can be only one person, heaven help her, her mother.
