At thirty-nine, Nancy Kissel had it all: glamour, wealth and the royal lifestyle of the expatriate wife. Not to mention three young children and what a friend described as "the best marriage in the universe" to Robert Kissel, a hugely successful investment banker. But that marriage ended abruptly one November night in 2003 in the bedroom of their luxury apartment high above Hong Kong's glittering Victoria Harbour.

Hong Kong prosecutors, who charged Nancy with murder, said she wanted to inherit Robert's millions and start a new life with her lover. She said she'd killed her husband in self-defence while fighting for her life against a brutal, cocaine-addicted husband. Her trial in 2005 captured attention worldwide, and less than a year after the verdict Rob's brother Andrew, a real estate tycoon facing prison for fraud and embezzlement was also found dead - tied up and stabbed in the basement of his multi-million dollar home by person or persons unknown.

Never Enough is the harrowing true story of Robert and Andrew Kissel, who wanted to own the world but instead wound up murdered half a world apart; and of Nancy Kissel, a riddle wrapped inside an enigma, for whom having it all might not have been enough.
