High-priced call girl Tawny Dell boasts a client list that's part Fortune 500, part Five Families. With a PhD in art history and a tidy chunk of money stashed offshore, she hangs up her G-string with plans to retire to a Mediterranean island to open a gallery. Lincoln Walsh, NYPD sex-crimes investigator, has other ideas. He wants Tawny to work undercover at a high-class bordello to discover if a murdered call girl worked there. The club, nicknamed Upper Eighties, is owned by an ex-hedge fund manager who'd do anything to hook Tawny into his harem. In exchange for Tawny's cooperation, Linc's office, in collaboration with Treasury, will see she avoids prison for failing to pay Uncle Sam his share from years of illegal earnings. But Tawny gets more than she bargained for―another dead prostitute, a mob boss who's an old client, and romantic stirrings for the hot New York cop sending her back into the world's oldest profession.
