She's their best agent. Now they've given her a new mission. Sarah Harris must kill presidential candidate Robert Montcrieff on his wedding day in St Patrick's Cathedral in Manhattan. There's just one problem: Sarah is Montcrieff's bride. She has one week to persuade them they've made a terrible mistake. Her frantic search for answers will bring her face to face with Sin for Salvation, an ancient cult with murderous rituals. Its members aspire to commit an ultimate sin known as Prohibition A. The cult preaches a shocking, hypersexual creed that has seduced Wall Street's highest flyers. They enlist recruits in the world's most exclusive nightclub, revolving around a sado-masochistic fantasy journey through Dante's nine circles of hell. But when its wealthy clientele leave the club, it's neither lust nor lucre they have on their minds. It's murder.
