Description Clara Starling lives a life of dull rules, deadly routine, and flavorless meals under her cold uncle's strict regime-until the day Uncle disappears, leaving Clara alone in his old mansion. When streetwise orphan Peter and his rescue cat arrive unexpectedly, the children seize the chance to live by their own rules. But when the pair's wild romps through the halls of Braithwaite Manor reveal a single worn ballet slipper, they are hurled into a mystery that will lead to London's glittering Royal Opera House and the unraveling of twisted Starling family secrets of poison, passion, and murder. Diabolical villains, plucky orphans, and glamorous ballet stars populate this absorbing adventure with a classic feel.
