Regan Reilly is back. The smart, saucy sleuth featured in all of Carol Higgins Clark's bestselling novels was last seen in Deck the Halls, the holiday thriller Carol wrote with her mother, Mary Higgins Clark.

Regan Reilly is in New York to attend a crime conference organized by her celebrity-author mother. A friend, Thomas Pilsner—the frenetic president of the Settlers' Club on Gramercy Park—calls Regan, desperately pleading for help. Thomas is distraught over the sudden suspicious deaths of two members of the Settlers' Club. The men had promised to donate a cache of valuable diamonds to save the Club. But now the diamonds are gone, the men are dead, and Thomas is a mess. He fears the police will suspect he is at the heart of both mysteries, and worse yet, he'll lose his job.

Enter Regan. Who better than the star of Decked, Snagged, Iced, and Twanged to solve the mystery of the missing diamonds and suspicious deaths? Who better to contend with the quirky characters around the Club, such as Lydia Sevatura, the self-styled "Princess of Love," who operates a dating service, and her butler, Maldwin Feckles, who has just opened the first school of butlering in New York City? And who better than Carol Higgins Clark, with her sparkling, canny prose, to keep the readers guessing to the end "who done it"?
