The eighteenth book in the hugely popular Peter Decker and Rina Lazarus series from New York Times bestselling author Faye Kellerman

Guy Kaffey thought his wealth could acquire anything- including the best security money can buy. When his family are gunned to death on their vast Butterfly Ranch estate, it's clear that he was tragically wrong.

Lieutenant Peter Decker of the LAPD is given the task of piecing together what happened. From the start, he suspects an inside job and that the answer lies with Kaffey's fortune. The daunting scale of Kaffey's business empire produces no shortage of suspects: from members of his bodyguard, to business partners, rival tycoons, even family members.

But as LA's ferocious street gangs hire themselves out to unknown paymasters in a cycle of revenge and death, Decker's own family is threatened. And if a billionaire like Kaffey can't protect his own, what hope does Decker have?
