Four months after the deadliest attack on the American homeland since 9/11, a terrorist plot leaves a trail of carnage through London’s glittering West End. The attack is a brilliant feat of planning and secrecy, but with one loose thread. The thread leads Gabriel Allon and his team to the south of France and to the gilded doorstep of one of the richest men in the country, Jean-Luc Martel, and his companion, Olivia Watson. A beautiful former British fashion model, Olivia pretends not to know the true source of Martel’s enormous wealth. And Martel, likewise, turns a blind eye to the fact he is doing business with a man whose objective is the very destruction of the West. Together, under Gabriel’s skilled hand, they will become an unlikely pair of heroes in the global war on terrorism. Written in seductive and elegant prose, the story moves swiftly from the glamour of Saint-Tropez to the grit of Casablanca and, finally, to an electrifying climax that will leave readers breathless long after they turn the final page.
