From the back of the book:
The Hamilton triplets - Madison, Park and Lexington - are accustomed to living in the public eye. Heiresses to a billion-dollar media empire, they have been raised in New York's most elite social circles and know first-hand the demands of being celebutantes.

When fashion editor Zahara Bell is found dead in a one-of-a-kind frock from Lex's unreleased clothing line, and the priceless Avenue Diamond goes missing, the sisters find themselves in the middle of a scandal that could sink their reputations and their father's companies for good.

The sisters need to stick closer together than ever before. The killer is still out there, and if they don't solve the case their threesome could become a twosome quicker than you can say Cartier.

Bought at the Penrith City Library book sale.
