A breakneck race against time and an implacable enemy. An anonymous young woman murdered in a run-down hotel, all identifying characteristics dissolved by acid. A father publicly beheaded in the blistering heat of a Saudi public square. A notorious Syrian biotech expert found eyeless in an a Damascus junkyard. Smoldering human remains on a mountainside in Afghanistan. A flawless plot to commit an appalling crime against humanity. One path links them all, and only one man can make the journey.
