From a true and shocking event-the bombing of lower Manhattan in September 1920-Jed Rubenfeld weaves a twisting and thrilling work of fiction as a physician, a female radiochemist, and a police official come to believe that the inexplicable attack is only part of a larger plan. It's a conspiracy that takes them from Paris to Prague, from the Vienna home of Sigmund Freud to the corridors of power in Washington, D.C., and ultimately to the depths of our most savage human instincts where there lies the shocking truth behind that fateful day.
