The school year's almost over, and Madison, Park and Lexington Hamilton are ready to trade in their Birkin bags for bikinis. Next stop, Capri! But before vacation comes work. Cleopatra, the newest, hottest and most expensive club in Manhattan, is opening - and it just happens to also be Hamilton Holdings' latest business venture. The girls must throw the party to end all parties. But this is one opening the sisters won't soon forget. Before the night ends, the body of fellow St. Cecilia Prep student Damien Kittle, the fifth Duke of Asherton, is found - a bloody wound on the side of his head, the hideous pink stiletto that took his life lying a few feet away. And what could be worse than a murder in their new club? The shoe belongs to another classmate: Concetta Conoli - the fatally unfashionable diet food heiress with a thing for British bad boys.

The paparazzi love a scandal, and they're ecstatic to get murderous dirt on another celebutante. Not only that, but they're determined to drag Cleopatra through the mud in Concetta's wake. Concetta might have bad taste, but Madison, Park and Lex can't stomach seeing a fellow heiress slammed, much less their own club. At first glance, the case appears to be open-and-shut. But the girls smell trouble. Murder is so out, but until this crime is solved, it's arrivederci, Italia. And the Hamilton sisters simply won't accept that as an option.
