Down-to-earth debutante (now newspaper society columnist) Nora Blackbird is having a meltdown--and it isn't because of Philadelphia's heat wave. Her sister Libby got herself run over by a Rolls-Royce and is recuperating at the Ritz, leaving her five kids in Nora's charge. And Emma Blackbird is on the brink of another bender, thanks to a shocking secret that could shake up the entire family. Adding to the turmoil, her best friend Lexie is accused of murdering Philadelphia philanthropist Hoyt Cavendish. It turns out Hoyt was financing his charitable contributions by pilfering form his clients, which means there's a long list of aristocrats with a motive for murder. And all three sisters are in a panic with the reappearance of their scheming parents.
