In March 1916, Joseph, a chaplain at the front, and Judith, an ambulance driver, are fighting not only the Germans but the bitter cold and the appalling casualties at Ypres. Scarcely less at risk, Matthew, an officer in England?s Secret Intelligence Service, fights the war covertly from London. Only Hannah, living with her children in the family home in tranquil Cambridgeshire, seems safe. Appearances, however, are deceiving. By the time Joseph returns home to Cambridgeshire, rumors of spies and traitors are rampant. And when the savagely brutalized body of a weapons scientist is discovered in a village byway, the fear that haunts the battlefields settles over the town?along with the shadow of the obsessed ideologue who murdered the Reavleys? parents on the eve of the war. Once again, this icy, anonymous powerbroker, the Peacemaker, is plotting to kill.
